SAP Rapid-Fire Questions &amp; Answers

Show answer

A sales organization is responsible for selling and liability to customers. A distribution channel represents how products reach customers, such as retail, wholesale or online. A division groups products, such as consumer and industrial. Together they form the sales area, which controls customer master data, pricing and sales documents. A sales organization is assigned to one company code.

What is record to report (R2R)?

Show answer

Record to report is the finance process from recording transactions to producing financial statements. It includes journal entries, accruals, asset postings, reconciliations, foreign currency valuation, intercompany reconciliation, period-end closing activities in FI and CO, and finally the balance sheet, profit and loss, and management reports. In S/4HANA, the Universal Journal and closing cockpit help speed it up.

What is a transaction code?

Show answer

A transaction code (T-code) is a short alias that opens a specific SAP screen or program, such as VA01 to create a sales order, ME21N to create a purchase order or FB60 to enter a vendor invoice. Users type it in the command field. Typing /n before the code ends the current transaction and opens the new one in the same session, and /o opens it in a new session.

What are SAP Fiori elements?

Fiori and SAPUI5 BasicsMedium

Show answer

Fiori elements are predefined floor plans, such as List Report, Object Page, Analytical List Page, Overview Page and Worklist, that generate the UI from metadata. The developer provides an OData service and CDS annotations describing fields, line items and facets, and the framework renders a consistent app with little JavaScript. This speeds development and keeps apps consistent and upgrade-safe compared to freestyle SAPUI5.

What is a variant in SAP?

Navigation: SAP GUI and FioriMedium

Show answer

A variant saves a set of input values for a selection screen so users do not retype them. Report variants are used for daily reports and background jobs. Layout variants save column order, sorting, filters and totals in ALV lists. Transaction variants and screen variants can hide or default fields in a transaction. In Fiori, users save views and filter variants in list reports.

What are internal tables in ABAP?

ABAP BasicsEasy

Show answer

Internal tables hold multiple rows of data in memory during program run time, similar to arrays of structures. Types are standard (index access, appended rows), sorted (kept sorted by key, binary search) and hashed (unique key access with constant time). Programs fill them with SELECT, then loop, read, modify or sort them. Choosing the right type matters for performance with large data.

What does SAP CO do?

Show answer

SAP CO (Controlling) supports internal management accounting. It tracks costs by cost centers, internal orders and projects, calculates product costs, and analyses profitability by customer, product or region through margin analysis. CO helps managers plan budgets, compare plan and actual costs, and allocate overheads. In S/4HANA, CO postings are in the same Universal Journal as FI, so both always reconcile.

What does SAP MM do?

Show answer

SAP MM (Materials Management) handles procurement and inventory. It covers purchase requisitions, requests for quotation, purchase orders, goods receipts, invoice verification, stock management, physical inventory and material valuation. MM works with FI for supplier invoices and stock accounting, with PP for material requirements, and with SD for stock availability. Its core process is procure to pay.

What is SAP GUI?

Show answer

SAP GUI is the classic desktop client used to log on to SAP systems and run transactions. SAP Logon lists available systems, and after logon the SAP Easy Access menu shows a tree of transactions. Variants include SAP GUI for Windows, SAP GUI for Java and SAP GUI for HTML (Web GUI in a browser). In S/4HANA, Fiori is the main experience, but many consultants still use SAP GUI for configuration and technical work.

What do greenfield, brownfield and selective data transition mean in S/4HANA migration?

ERP and SAP FundamentalsMedium

Show answer

Greenfield is a fresh implementation: new processes are designed and only selected master data and open items are migrated. Brownfield is a system conversion of an existing ECC system to S/4HANA, keeping configuration, custom code and history. Selective data transition, sometimes called bluefield, is a mix where a new shell system is built and chosen data, company codes or years are moved. The choice depends on process quality, custom code volume, history needs and timeline.

What is a plant in SAP?

Show answer

A plant is an operating location such as a factory, warehouse, distribution centre or branch, where materials are produced, stored or sold. It is assigned to exactly one company code. Stock, material valuation (usually at plant level), MRP and production happen at plant level. Under a plant there are storage locations that represent physical areas where stock is kept.

What is a company code?

Show answer

A company code is the smallest organizational unit for which a complete, independent set of financial statements (balance sheet and profit and loss) can be produced for legal purposes. Each legal entity, such as an Indian private limited company, is usually one company code with its own currency, chart of accounts and fiscal year variant. All financial postings carry a company code.

What is ERP and why do businesses use it?

Show answer

ERP (Enterprise Resource Planning) is software that runs core business processes such as finance, purchasing, sales, production, inventory and HR on one shared database. Businesses use it to remove separate spreadsheets and disconnected systems, so a sales order, a goods issue and the accounting entry all update the same data in real time. The result is one version of the truth, better control, faster month-end closing and easier compliance with tax and audit rules.

What are the main types of Fiori apps?

Show answer

Transactional apps let users create, change or approve business documents such as purchase requisitions. Analytical apps show KPIs and drill-down charts from live data using CDS views. Fact sheets show key information about an object and links to related objects; in S/4HANA many are now object pages. SAP also provides SAP GUI-based apps inside the launchpad for transactions without a native Fiori version.

What does SAP PP do?

Show answer

SAP PP (Production Planning) supports manufacturing. It uses master data such as bill of materials (BOM), work centers and routings, and processes such as demand management, MRP, planned orders, production orders or process orders, goods issue of components, confirmations and goods receipt of finished goods. PP connects sales demand to procurement and production, and it updates costs in CO for each order.

What is the SAP Fiori launchpad?

Show answer

The Fiori launchpad is the browser-based entry point for S/4HANA users. It shows tiles and links grouped into spaces and pages based on the user's roles. Each tile opens a Fiori app or a classic transaction in a web GUI. Users can search apps, personalise their home page, see notifications and use the same launchpad on desktop, tablet or phone.

What is the SAP Fiori Horizon theme?

Fiori and SAPUI5 BasicsEasy

Show answer

Horizon is the current visual theme for SAP Fiori, replacing older themes like Quartz and Belize. It offers a modern look with updated colours, typography, icons and better accessibility, and it has light, dark and high-contrast variants. It is the default theme in recent S/4HANA and BTP releases. Users can change themes in the launchpad settings if the administrator allows it.

What are work processes in an SAP application server?

S/4HANA Architecture and LandscapeMedium

Show answer

Work processes are the operating system processes that execute user and system requests. Dialog processes handle interactive steps, update processes write database changes asynchronously (V1 and V2), background processes run batch jobs, enqueue manages locks, and spool handles printing. The dispatcher assigns requests to free work processes. Basis checks them in SM50 or SM66, and long-running dialog steps often point to performance problems.

What are the ways to enhance standard SAP without modifying it?

ABAP BasicsMedium

Show answer

Options include user exits and customer exits (older), BAdIs (Business Add-Ins, classic and new kernel-based), implicit and explicit enhancement points, and in S/4HANA, key user extensibility with custom fields and custom logic in Fiori apps. Developer extensibility uses released objects and ABAP Cloud. Modifications through the modification assistant are the last resort because they must be checked at every upgrade.

What are SAP Ariba and SAP Concur?

Show answer

SAP Ariba is a cloud procurement platform for sourcing, contracts, supplier management, guided buying and the Ariba Network, where buyers and suppliers exchange purchase orders and invoices. SAP Concur handles employee travel booking and expense reporting. Both integrate with S/4HANA, which remains the system of record for accounting and payments. Companies use them to extend core MM and FI processes.

What is the difference between a role, a catalog and a space in Fiori?

Navigation: SAP GUI and FioriMedium

Show answer

A business catalog groups apps that belong to a business area and controls which apps a user can access. A business role, built in PFCG, contains catalogs and gives authorizations. Spaces and pages control layout, meaning how tiles are arranged on the launchpad home. So catalogs and roles answer what the user can open, and spaces and pages answer how it appears.

What is the role of the SAP Gateway and OData in S/4HANA?

S/4HANA Architecture and LandscapeMedium

Show answer

SAP Gateway exposes SAP data and logic as OData services over HTTP. Fiori apps and external systems call these services to read and change business data. In S/4HANA, Gateway can run embedded in the same system or as a separate hub. Modern apps use OData V2 or V4 services generated from CDS views and the RAP framework, and services are activated in transaction /IWFND/MAINT_SERVICE.

What do SAP QM and PM do?

SAP Modules OverviewMedium

Show answer

QM (Quality Management) plans and records inspections, for example at goods receipt or during production, using inspection plans, inspection lots, results recording and usage decisions, and manages quality notifications. PM (Plant Maintenance, now part of Asset Management) maintains equipment and functional locations through notifications, maintenance orders, preventive maintenance plans and costs. Both are important in manufacturing, pharma and process industries.

What are the key simplifications in S/4HANA compared to ECC?

S/4HANA Architecture and LandscapeMedium

Show answer

Main simplifications are: no aggregate and index tables in many areas, the Universal Journal for finance, Business Partner as the single master for customers and vendors, a simplified inventory table MATDOC, a longer 40-character material number option, new credit management, output management based on BRF+, and Fiori as the main user experience. SAP lists all these changes in the Simplification List for each release.

How many sessions can a user open in SAP GUI?

Show answer

By default a user can open up to six sessions (windows) per logon, controlled by the profile parameter rdisp/max_alt_modes, which Basis can increase up to sixteen. Each session runs its own transaction, so a user can compare a purchase order in one window and an invoice in another. Too many sessions per user can add load on the application server.

What is an SAP system landscape?

Show answer

A landscape is the set of systems used to develop, test and run SAP. A typical three-system landscape has Development (DEV) for configuration and code, Quality (QAS) for testing, and Production (PRD) for live business. Changes move from DEV to QAS to PRD through transports. Larger landscapes add sandbox, pre-production, training and separate systems such as SAP BW or SAP Gateway.

What are IDocs?

Business Processes and IntegrationMedium

Show answer

An IDoc (Intermediate Document) is SAP's standard format for exchanging data asynchronously between systems. It has a control record, data segments and status records. IDocs are sent through ALE and partner profiles (WE20) with ports (WE21). Common message types include ORDERS for purchase orders, INVOIC for invoices and MATMAS for materials. They are monitored in WE02 or WE05, and BD87 reprocesses errors.

What does SAP FI do?

Show answer

SAP FI (Financial Accounting) records all external financial transactions for legal reporting. Its main parts are General Ledger, Accounts Payable, Accounts Receivable, Asset Accounting and Bank Accounting. FI produces the balance sheet and profit and loss statement for each company code, handles taxes such as GST and TDS in India, and supports period closing. Every logistics transaction that has value creates an FI document.

What is the difference between implementation, support and rollout projects?

Show answer

An implementation project sets up SAP from scratch for a company. A support or AMS (Application Management Services) project keeps a live system running by solving tickets, small changes and month-end issues under SLAs. A rollout project copies an existing template to a new country or company code, adding local tax, language and legal needs, such as GST and e-invoicing for India. Many freshers in Indian IT services start in support projects.

What happens in accounting when goods are received against a purchase order?

Show answer

Goods receipt for a stock material posts a material document and an accounting document. The stock account is debited and the GR/IR clearing account is credited at the PO price. When the supplier invoice is posted in MIRO, GR/IR is debited and the supplier account is credited, and differences go to price difference accounts. The account assignment is decided by automatic account determination (OBYC).

What is an organizational structure in SAP?

Show answer

The organizational structure is the set of units that represent how a company is legally and operationally built in SAP, such as client, company code, plant, storage location, sales organization, purchasing organization and controlling area. These units are defined in customizing and assigned to each other. Every transaction is recorded against them, so the structure decides how reporting, pricing, stock and accounting work.

What is a client in SAP?

Show answer

A client is an independent business unit inside one SAP system, identified by a three-digit number such as 100 or 200. Each client has its own master data, transaction data and users, while repository objects such as programs and tables are shared across all clients. Configuration can be client-specific or cross-client. A development system often has a configuration client, a unit test client and a sandbox client.

What is SAP EWM?

SAP Modules OverviewMedium

Show answer

SAP Extended Warehouse Management handles complex warehouse operations such as inbound, putaway strategies, picking waves, packing, cross-docking, yard management, labour management and RF devices. In S/4HANA it can run embedded in the same system or decentrally. Old Warehouse Management (WM) is not the target in S/4HANA, so many projects move warehouses to EWM or use simpler Stock Room Management.

What happens in accounting when goods are issued for a delivery and billed?

Show answer

At post goods issue, the cost of goods sold account is debited and the inventory account is credited at the material's valuation price. At billing, the customer account is debited and revenue and output tax (GST) accounts are credited. Revenue accounts are found through revenue account determination (VKOA), using keys like account assignment group of customer and material.

What is ABAP?

ABAP BasicsEasy

Show answer

ABAP (Advanced Business Application Programming) is SAP's programming language for building reports, enhancements, interfaces, forms and services on the SAP application server. It has built-in database access through Open SQL (ABAP SQL), internal tables for in-memory data, and strong integration with the data dictionary.

What is the difference between F1 and F4 help?

Show answer

F1 gives documentation for the field where the cursor is, and its technical information button shows the table, field name, data element and program, which consultants use often. F4 shows the list of allowed values for a field, such as all company codes or plants, with search helps to filter. Together they help users enter correct data and help consultants find where data is stored.

What is SAP SuccessFactors and how does it relate to S/4HANA?

Show answer

SAP SuccessFactors is SAP's cloud HR suite. It covers core HR (Employee Central), payroll, recruiting, onboarding, performance, learning and compensation. Most new SAP customers use it instead of on-premise SAP HCM. It integrates with S/4HANA to send employee and cost center data, so that payroll postings and travel expenses reach finance correctly. SAP has also offered an on-premise HCM option for S/4HANA called H4S4.

What is SAP and what does SAP S/4HANA stand for?

Show answer

SAP is a German software company and also the common name for its ERP products. SAP S/4HANA stands for SAP Business Suite 4 SAP HANA. It is the fourth generation ERP suite, built to run only on the SAP HANA in-memory database. It replaced SAP ECC (ERP Central Component) as the main ERP product, with a simplified data model, real-time analytics and the Fiori user experience.

What is the ABAP Data Dictionary?

ABAP BasicsEasy

Show answer

The ABAP Dictionary (transaction SE11) is the central place where database tables, views, data elements, domains, structures, table types, search helps and lock objects are defined. A domain defines technical type and value range, and a data element adds business meaning and field labels. Definitions are shared by all programs, so changes are consistent across the system and tables are created in the database on activation.

What is the difference between SAP ECC and SAP S/4HANA?

Show answer

ECC runs on several databases such as Oracle, DB2 or HANA, uses many aggregate and index tables, and mainly uses SAP GUI. S/4HANA runs only on HANA, removes most aggregate tables, uses the Universal Journal (ACDOCA) for finance, Business Partner instead of separate customer and vendor masters, and offers Fiori apps. Mainstream maintenance for ECC 6.0 ends in 2027, which is why many Indian clients are running S/4HANA migration projects now.

What are the main functional modules in SAP S/4HANA?

Show answer

Key areas are Finance (FI) for legal accounting, Controlling (CO) for internal cost and profit analysis, Materials Management (MM) for purchasing and inventory, Sales and Distribution (SD) for selling and billing, Production Planning (PP) for manufacturing, Quality Management (QM), Plant Maintenance (PM), Warehouse Management (EWM), and Project System (PS). HR is now mostly delivered by SAP SuccessFactors, while S/4HANA keeps some on-premise HCM options.

What is ABAP Cloud and the tier model for extensions?

ABAP BasicsHard

Show answer

ABAP Cloud is the development model that allows only released APIs, ADT tooling and modern constructs like RAP and CDS, so code survives upgrades. SAP describes a three-tier model for S/4HANA private and on-premise: tier 1 is ABAP Cloud using released objects, tier 2 is cloud API enablement where wrappers expose unreleased functions as released ones, and tier 3 is classic ABAP for remaining needs. Teams aim to keep most new code in tier 1.

What is the Business Partner in S/4HANA?

Show answer

Business Partner (BP) is the single master data object for customers, suppliers and other partners in S/4HANA. One BP holds general data such as name and address, and roles add customer data (financial and sales views) or supplier data (financial and purchasing views). Transaction BP replaces old transactions like XD01 and XK01. Customer-vendor integration (CVI) keeps the BP synchronised with the classic customer and vendor tables.

What is a transport request?

Show answer

A transport request is a container that records changes made in development, such as configuration or ABAP objects, so they can be moved to quality and production in a controlled way. Workbench requests carry repository objects that are cross-client, and customizing requests carry client-specific configuration. Requests are released in DEV and imported by Basis or a tool such as SAP Cloud ALM or ChaRM. Transaction SE09 or SE10 manages them.

What is ALV and why is it common in SAP reports?

Navigation: SAP GUI and FioriMedium

Show answer

ALV (ABAP List Viewer) is SAP's standard grid for displaying lists. It lets users sort, filter, subtotal, change columns, export to spreadsheet and save layouts without extra coding. Most standard and custom reports use ALV, and in Fiori the equivalent is the smart table in list report apps. Knowing how to use ALV layouts is a basic skill for any SAP user or consultant.

What is SAP Fiori?

Fiori and SAPUI5 BasicsEasy

Show answer

SAP Fiori is SAP's design system and user experience for business apps. It follows principles of being role-based, adaptive, simple, coherent and delightful, so each user sees only the apps for their job on any device. Fiori apps are built with SAPUI5 and accessed through the Fiori launchpad. In S/4HANA, Fiori is the target user interface, and the current design language is SAP Fiori with the Horizon theme.

What is the difference between row store and column store in HANA?

Show answer

A row store keeps all fields of a record together, which suits reading or writing whole records. A column store keeps each column's values together, which compresses well and makes scanning, filtering and aggregating a few columns across millions of rows very fast. Most S/4HANA application tables are column tables. Row tables are used only for some small, frequently updated technical tables.

What is the procure to pay (P2P) process in SAP?

Show answer

Procure to pay is the purchasing cycle: a purchase requisition is created, a source is selected, a purchase order is sent to the supplier, goods are received with MIGO, the supplier invoice is verified with MIRO using a three-way match of PO, goods receipt and invoice, and the payment is made with the payment run F110. Each step creates documents that link MM and FI.

What is SAP Activate methodology?

Show answer

SAP Activate is SAP's current delivery framework for S/4HANA projects. It combines SAP Best Practices (ready business process content), guided configuration and an agile, iterative approach. Its phases are Discover, Prepare, Explore, Realize, Deploy and Run. Instead of writing a long blueprint first, teams run fit-to-standard workshops on a preconfigured system, record gaps in a backlog and deliver in sprints, which shortens timelines and reduces custom code.

What is the order to cash (O2C) process in SAP?
