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.
02
Inbound purchase order IDocs from a customer are failing in status 51. What do you do?
Status 51 means application error. I open the IDoc in WE02, read the status message, and check the data segments, for example an unknown customer material number, missing partner function or invalid pricing. I correct master data or mappings, then reprocess the IDoc with BD87. If many fail, I find the common cause, inform the sender if the data is wrong, and add monitoring alerts.
SAP Analytics Cloud (SAC) is SAP's cloud tool for business intelligence, planning and predictive analytics. It connects live to S/4HANA, BW or Datasphere, or imports data, to build stories and dashboards. Finance teams use its planning features for budgets and forecasts. It is commonly used for management dashboards because it combines reporting and planning in one interface.
04
A transport moved to quality but the configuration is not visible there. What do you check?
I check the import log in STMS to confirm the request was imported without errors (return code 0 or 4). Then I confirm the change was saved in the right request and client, and whether it was client-specific customizing that needs a client copy or import into the specific QAS client. I also check for missing dependent transports, such as a new field or table that the configuration relies on, and object locks in another request.
05
What are the levels at which material master data is maintained?
Some data is at client level, such as material description, base unit and material group, and applies to all plants. Plant-level data includes MRP, purchasing, work scheduling and usually valuation. Storage-location-level data covers storage bin and picking area. Sales data is at sales organization and distribution channel level, and warehouse data at warehouse number level. This lets each unit control its own settings.
Read all needed rows once with a join or FOR ALL ENTRIES, then read from the internal table in the loop.
SELECT ebeln, ebelp, matnr FROM ekpo
WHERE ebeln IN @s_ebeln
INTO TABLE @DATA(lt_items).
IF lt_items IS NOT INITIAL.
SELECT matnr, maktx FROM makt
FOR ALL ENTRIES IN @lt_items
WHERE matnr = @lt_items-matnr AND spras = @sy-langu
INTO TABLE @DATA(lt_text).
ENDIF.
SORT lt_text BY matnr.
Always check the driver table is not empty before FOR ALL ENTRIES.
07
How do you find the table and field name behind a screen field?
Place the cursor on the field and press F1, then click the Technical Information button. The pop-up shows the program, screen number, table or structure name, field name and data element. If it shows a structure, I use SE11 or the where-used list to find the database table, or run an SQL trace in ST05 while saving the document to see which tables are written.
08
How do Fiori apps get their data from the back end?
A Fiori app is a SAPUI5 web app running in the browser. It calls an OData service exposed by SAP Gateway. The service reads or writes data through CDS views and the RAP framework or older SEGW-built classes, which access HANA tables. Authorization is checked on both the launchpad catalog and the back-end service and data level. Logs in /IWFND/ERROR_LOG help troubleshoot failed calls.
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.
10
What are the main integration technologies used with S/4HANA?
S/4HANA integrates through OData and REST APIs, SOAP web services, IDocs, RFC and BAPIs, and events through SAP Event Mesh or Advanced Event Mesh. Middleware such as SAP Integration Suite (Cloud Integration) or older SAP PI/PO maps and routes messages. The SAP Business Accelerator Hub (api.sap.com) lists released APIs. Modern projects prefer released APIs and events over direct table access.
S/4HANA can run on-premise in the customer's data centre or a hyperscaler they manage, as S/4HANA Cloud Private Edition (usually sold through RISE with SAP, a single-tenant system managed by SAP), or as S/4HANA Cloud Public Edition (multi-tenant SaaS with quarterly updates and limited customization). On-premise and Private Edition allow classic extensions and full customizing, while Public Edition needs a clean core and standard processes.
12
A business team wants to hide some fields in a transaction they use daily. What options exist?
For SAP GUI transactions I can use transaction variants and screen variants (SHD0) to hide, default or make fields display-only, then assign a variant transaction code. For many documents, field status groups or field selection settings in customizing control required, optional or suppressed fields. For Fiori apps, key users can use adapt UI to hide fields. I choose the option that does not modify SAP code.
13
How do you generate a Fiori elements app with SAP Fiori tools?
In Business Application Studio or VS Code, open the Fiori application generator, choose a floor plan such as List Report Page, select the data source by connecting to a system or BTP destination and picking the OData service, choose the main entity and navigation, enter project details, and generate. Then preview with live or mock data, add annotations with the guided development tool, and deploy to the ABAP repository.
14
How do you find which Fiori app replaces a classic transaction?
Open the SAP Fiori Apps Reference Library and search with the transaction code, such as ME21N. The results show matching apps with app ID, type, roles, catalogs and required back-end services. In the system, the Fiori launchpad content manager and the app search help find what is already active. Many classic transactions run as SAP GUI for HTML tiles when no native app exists.
PS manages projects such as capital investments, construction or engineer-to-order products. It uses Work Breakdown Structure (WBS) elements for cost and revenue planning and networks with activities for scheduling. Actual costs from purchasing, time and materials are collected on WBS elements, and results analysis and settlement move costs to assets or profitability. It integrates closely with FI, CO, MM and PP.
16
Write a basic CDS view entity that shows sales order items with their header data.
A view entity joins header and item with an association and exposes fields with aliases.
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'Sales order items'
define view entity ZI_SalesOrderItem
as select from vbap as Item
association [1..1] to vbak as _Header
on $projection.SalesOrder = _Header.vbeln
{
key Item.vbeln as SalesOrder,
key Item.posnr as SalesOrderItem,
Item.matnr as Material,
Item.kwmeng as OrderQuantity,
_Header.kunnr as SoldToParty,
_Header
}
17
The business needs a nightly interface file of open sales orders. How would you build it?
I would write a report that selects open orders using a CDS view or ABAP SQL with proper filters, formats the data to the agreed layout, and writes the file to an application server directory or sends it through SAP Integration Suite. I would add a selection screen with variants, logging with the application log (SLG1), error notifications, and schedule it in SM36 or Application Jobs. Testing covers volume and format checks.
18
An approval Fiori app shows no items even though workflows exist. What do you check?
I check that workflow items are actually assigned to the user in the inbox, using workflow logs in SWIA or the Manage Workflows app. Then I confirm the user has the My Inbox app role and back-end authorization, the OData services for the task gateway are active, and the task definitions are registered for the inbox scenario. Substitution rules and outdated cache can also hide items.
19
How do you find which transport request contains a particular change?
For a repository object, open it in SE80 or SE11 and use Utilities then Versions to see version history with request numbers, or search the object in SE03 'Search for Objects in Requests'. For customizing, open the table or view in SM30, use Utilities then Change Logs if logging is active, or search the table key in SE03. Transport history in STMS shows when requests were imported into each system.
20
What is intercompany sales or stock transfer in SAP?
When one company code sells or transfers goods to another in the same group, SAP supports intercompany processes. For a stock transport order, the receiving plant creates a PO, the supplying plant delivers and posts goods issue, intercompany billing posts revenue in the supplying company code, and the receiving company code books the supplier invoice, often through IDocs. Elimination happens later in group reporting.
21
Show a simple CDS annotation setup for a Fiori elements list report.
Code pushdown means moving data-intensive logic from the ABAP application server to the HANA database, so calculations happen close to the data and only results travel. Techniques include CDS views, ABAP SQL with aggregations and expressions, and AMDP (ABAP Managed Database Procedures) written in SQLScript. Instead of selecting millions of rows and looping in ABAP, the database filters and aggregates, which improves performance a lot.
23
What are work processes in an SAP application server?
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.
24
A user gets the message 'You are not authorized to use transaction'. How do you handle it?
I ask the user to run SU53 right after the error, which shows the failed authorization check, including object and missing value. I compare it with their roles in SU01. If the access is valid for their job, I raise an access request through the approved process so the security team adds the correct role, rather than giving direct access. I also check segregation of duties rules before approval.
Situation: our team had frequent production defects. Task: improve quality without slowing delivery. Action: I introduced a simple checklist covering naming, performance, error handling and ATC checks, and paired review for every transport. I kept comments respectful and focused on code, not people. Result: production defects from custom code dropped noticeably over two quarters, and juniors learned faster from review comments.
26
Tell me about a time you solved a cross-module issue.
Situation: invoices were posting to the wrong revenue account for a new product line. Task: find the cause across SD and FI. Action: I traced the billing document, found that the new materials had no account assignment group, and the VKOA entry was missing for the new combination. I fixed master data, added configuration through a transport, and reposted documents with finance. Result: correct revenue from that day and no audit issue.
27
An invoice is blocked for payment after MIRO. Why might this happen and how is it released?
It is usually blocked because of tolerance limits, for example price or quantity differences between PO, goods receipt and invoice, or a manual payment block. I check the blocking reason on the invoice. After the buyer confirms the price or quantity or the goods receipt is posted, the invoice is released with MRBR or the Release Blocked Invoices app. Tolerance keys are configured in OMR6.
The SAP S/4HANA Migration Cockpit (transaction LTMC in older releases, now the Migrate Your Data Fiori app) is the standard tool to load master and open item data in greenfield projects. It uses predefined migration objects such as customers, suppliers, materials, open AR and AP items and fixed assets, with staging tables or file templates. It validates data, maps values and posts through standard APIs, replacing older LSMW for most loads.
29
A new user finds Fiori confusing compared to SAP GUI. How do you help?
I show them their launchpad layout and the few apps they need, how to search apps, use filters and save views, and how list report and object page work together. I compare one familiar transaction with its Fiori app side by side. A short quick reference guide and a follow-up after a week usually build confidence, and their feedback helps improve role design.
30
What is ABAP Cloud and the tier model for extensions?
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.
31
A delivery cannot be created for a sales order. What do you check?
I check the sales order for incompleteness, credit block or delivery block in the header or schedule line, and whether the requested delivery date and confirmed quantity exist after availability check. Then I check shipping point determination, the item category's delivery relevance and the delivery type copy control. VL10 or the delivery due list shows the log of why an order was not selected, which usually points to the exact reason.
32
Describe a situation where a go-live was at risk and how you handled it.
Situation: two weeks before go-live, integration testing showed failing bank interfaces. Task: protect the date without risking business. Action: I set up a daily war room with the bank, middleware and finance teams, split defects by owner, and prepared a manual payment fallback with approval. Result: most defects were fixed in eight days, the fallback covered the remaining bank for one week, and we went live on schedule with no missed vendor payments.
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.
CVI is the synchronisation framework that links Business Partners with the classic customer (KNA1, KNB1, KNVV) and vendor (LFA1, LFB1, LFM1) tables. In S/4HANA every customer and vendor must exist as a BP. In a brownfield conversion, CVI must be configured and all customers and vendors converted to BPs in ECC before the technical conversion, which is a major pre-conversion task.
RISE with SAP is a subscription bundle that packages S/4HANA Cloud (mostly Private Edition), infrastructure on a hyperscaler such as AWS, Azure or Google Cloud, technical managed services, SAP BTP credits, and tools such as SAP Signavio for process insight. The customer pays one contract to SAP instead of buying licences, hardware and hosting separately. GROW with SAP is a similar offer focused on Public Edition for mid-size companies.
36
A company wants better warehouse control with RF scanners. Which SAP options would you discuss?
I would discuss embedded EWM in S/4HANA for scanner-based putaway, picking and packing with strategies and storage bin control, and decentral EWM if the warehouse is very large or must run independently. For simpler sites, inventory management with storage locations and Stock Room Management may be enough. The choice depends on volume, complexity, automation and budget.
37
A fresher asks which SAP module to choose. How would you guide them?
I would match the module to their background and interest. Commerce, accounting or CA students fit FICO. Supply chain, mechanical or operations graduates fit MM, PP or EWM. Those who like selling processes fit SD. Coders fit ABAP or Fiori development, and system-oriented people fit Basis or security. I would also suggest first learning S/4HANA basics, then one module deeply, plus integration with its neighbour modules.
38
What is the Simplification List and the Readiness Check?
The Simplification List documents every functional and technical change in an S/4HANA release, such as removed transactions, changed tables and mandatory replacements. The SAP Readiness Check is a tool that analyses an existing ECC system and reports which simplification items apply, custom code impact, add-on compatibility, data volume and sizing. Together they help a team estimate the effort and plan a conversion project.
39
Tell me about a time you had to explain an SAP issue to a non-technical business user.
Situation: a sales manager was upset that orders were blocked. Task: explain the cause without jargon. Action: I showed him in simple terms that the customer had crossed the credit limit, so the system stopped the delivery as designed, and walked through who can release it and how. Result: he understood the control, the finance team released valid orders faster, and we added a daily report so his team could see blocked orders early.
40
What is the difference between SAP Easy Access menu and the IMG?
The SAP Easy Access menu is the user menu for daily business transactions, organised by area such as Logistics or Accounting. The IMG (Implementation Guide), opened with transaction SPRO, is the configuration tree used by consultants to set organisational units, document types, number ranges, pricing and other customizing. Business users rarely get SPRO access, and IMG changes are recorded in customizing transports.
