1. What are the main components of SAP system architecture?
SAP has 3 layers – Presentation (GUI), Application server, and Database. Application server handles processing and DB stores data. For example, user logs in via GUI, request goes to application server, data comes from DB.
2. What is the role of the Application Server in SAP?
The Application Server in SAP acts as the central processing unit, handling business logic, data processing, and communication between the presentation layer and the database layer.
3. How do you check SAP system status quickly?
Use SM51 for app servers and SM66 for global work processes.
For system info, use System → Status.
We always need to check this first when users complain about slowness.
4. What is dispatcher in SAP?
Dispatcher distributes user requests to work processes.
It acts like a traffic controller. We can monitor it in SM50/SM66.
5. How do you check work process status?
Use SM50 (local) or SM66 (global) to check the status of work processes.
You can see the current state, execution time, and other details.
Look for long-running or stopped processes. If stuck, sometimes we need to cancel it carefully.
6. What is instance profile vs default profile?
An instance profile contains settings specific to a particular SAP instance, while a default profile contains general settings that apply to all instances. Both are stored in OS level files. These usally changes after restart.
7. How do you create a user in SAP?
Use SU01 → Create → assign roles and profiles.
Always need to set initial password and user type properly. For example: Dialog user for normal login.
8. Difference between roles and profiles?
Roles define the authorization and access rights for users, while profiles contain the settings and configurations for the SAP system. Roles are assigned to users, and profiles are assigned to roles. Roles are easier to manage. Always assign roles, not direct profiles.
9. How do you lock/unlock a user?
Use SU01 → Display → Lock/Unlock user.
Always ensure you have the necessary authorization before performing these actions.
You can also mass unlock via SU10. Helpful when multiple users get locked after password attempts.
10. What is TMS and where do you configure it?
TMS (Transport Management System) is used for managing transport requests in SAP.
It is configured in the SAP GUI under Transaction STMS.
We used to define domain controller and systems here.
