01

What is SAP GUI?

Save to ▾
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.
02

What is a transaction code?

Save to ▾
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.
03

What is the SAP Fiori launchpad?

Save to ▾
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.
04

What are the common command field shortcuts in SAP GUI?

Save to ▾
Show answer
/n opens a new transaction in the same session, /o opens a new session, /nend logs off with confirmation, /nex logs off without confirmation, /i closes the current session, and /h switches on debugging. Typing search_sap_menu finds transactions in the menu. F1 shows field help, F4 shows possible values, and F8 executes reports. These shortcuts save a lot of time for consultants and power users.
05

What is the difference between F1 and F4 help?

Save to ▾
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.
06

What are the main types of Fiori apps?

Save to ▾
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.
07

How many sessions can a user open in SAP GUI?

Save to ▾
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.
08

What is the SAP Fiori Apps Reference Library?

Save to ▾
Show answer
It is an online SAP catalogue that lists all Fiori apps with their app ID, business role, supported releases, required OData services, business catalogs and roles, and implementation steps. Consultants use it to find the right standard app for a process and to know which services and catalogs to activate. Searching by transaction code shows which Fiori app replaces a classic transaction.
09

How do you find the table and field name behind a screen field?

Save to ▾
Show answer
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.
10

How do you add frequently used transactions to favourites?

Save to ▾
Show answer
In the SAP Easy Access menu, right-click a transaction in the tree and choose Add to Favorites, or use Favorites then Insert Transaction and type the code. Favourites can be grouped into folders and can also include web links. In the Fiori launchpad, users personalise their page by adding apps from the app finder or search. This keeps daily work fast and organised.
11

How did you learn to navigate SAP when you were new?

Save to ▾
Show answer
Situation: when I joined, SAP screens felt overwhelming. Task: become productive within two weeks. Action: I kept a list of the transactions and Fiori apps my team used most, practiced each process on the training client, used F1 technical information to understand fields, and asked a senior to review my notes. Result: in two weeks I could handle basic tickets myself and created a quick reference sheet that new joiners still use.
12

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

Save to ▾
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.
13

What is a variant in SAP?

Save to ▾
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.
14

What is SAP GUI scripting and when is it used?

Save to ▾
Show answer
SAP GUI scripting is an automation interface that records and replays user actions in SAP GUI using VBScript or other languages. Teams use it for repetitive data entry, test automation and simple bots. It must be enabled on the server with profile parameter sapgui/user_scripting and on the client. Because it depends on screen layouts, it breaks when screens change, so APIs or Migration Cockpit are better for large loads.
15

What is the difference between SAP Easy Access menu and the IMG?

Save to ▾
Show answer
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.
16

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

Save to ▾
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.
17

How do Fiori apps get their data from the back end?

Save to ▾
Show answer
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.
18

A user says a tile is missing from their Fiori launchpad. What do you check?

Save to ▾
Show answer
I check whether the user's business role contains the business catalog that holds the app, and whether that role is assigned and active in SU01 or PFCG. Then I confirm the tile is placed on a space and page assigned to the role or that the user can find it in app search. If the tile shows but fails, I check that the OData service is active and that the user has the back-end authorization. Clearing the launchpad cache can also help.
19

A user gets the message 'You are not authorized to use transaction'. How do you handle it?

Save to ▾
Show answer
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.
20

A business team wants to hide some fields in a transaction they use daily. What options exist?

Save to ▾
Show answer
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.
21

A Fiori app shows an error when opened. How do you troubleshoot?

Save to ▾
Show answer
I open the browser developer tools to see failing network calls and the HTTP code. Then in the back end I check /IWFND/ERROR_LOG on the gateway and /IWBEP/ERROR_LOG on the back end for the service error, ST22 for dumps, and SU53 for missing authorizations. I confirm the OData service is activated in /IWFND/MAINT_SERVICE and the ICF nodes are active in SICF. Finally I clear the cache and test again.
22

How do you export an ALV report to Excel and save a layout?

Save to ▾
Show answer
In the ALV toolbar, choose Export then Spreadsheet, select the format such as XLSX, and save the file. To save a layout, change columns, sorting and filters, then click Save Layout, give a name, and tick user-specific or default as needed. Next time, choose the layout from the dropdown. A default layout opens automatically, which helps teams share a common view.
23

How do you find which Fiori app replaces a classic transaction?

Save to ▾
Show answer
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.
24

How do you schedule a report to run in the background every night?

Save to ▾
Show answer
Create and save a variant for the report. In SM36 define a job name and class, add a step with the program and variant and a user with correct authorizations, and set the start condition as a date and time with periodic value daily. Save the job, then monitor it in SM37. In Fiori, the Application Jobs app does the same for job templates.
25

Tell me about a time you improved productivity for users.

Save to ▾
Show answer
Situation: accounts users spent an hour daily filtering an ALV report. Task: reduce manual effort. Action: I studied their steps, created report variants and saved layouts, scheduled the report in the background with email output, and trained the team. Result: the daily effort dropped to about ten minutes, and the team lead asked me to do the same for two other reports.
