Master S/4HANA authorization issues: A practical guide with Visio overview

Authorization issues in SAP S/4HANA can significantly impact your day-to-day work. As an SAP authorization expert, I would like to present a systematic troubleshooting overview that may help you to efficiently overcome these challenges.

The challenge

SAP authorizations are as diverse as the business processes they protect. Small mistakes can have far-reaching consequences. The trick is to develop a flexible but clearly regulated authorisation concept that can adapt to changing requirements without becoming inconsistent. The world of authorizations has not become any easier with S/4HANA.

A systematic approach to troubleshooting

To effectively solve authorization problems, I have created an overview that structures the troubleshooting process from the client level to the backend system. Let's go through the key steps:

1. client level (Fiori Launchpad)

• Fiori Launchpad App Support: Provides important information such as the SAP Fiori ID, business server page name, service node and OData service, as well as any authorisation, gateway or runtime errors that have occurred.
• Browser Developer Tools (F12):
• Elements: Check the loaded components
• Console: JavaScript errors and runtime problems
• Sources: Direct access to JavaScript code Custom code file debugging
• Network: Checking the OData HTTP URLs Requests, responses and error messages

2. Front-End Server (FES)

• /IWFND/MAINT_SERVICE (OData configuration):
• Model cache cleanup
• Metadata reload
• SICF configuration
• Service addition and configuration
• Gateway client: Cache cleanup, cache rebuild, request execution
• Service Implementation: Checking for errors or insufficient authorizations
• RFC Connection (SM59): Ensuring the correct configuration between the front end and the back end
• /IWFND/ERROR_LOG (OData Error Log): Analysing data transfer problems between FES and BES

3. Back-End Server (BES)

• STAUTHTRACE: Detailed analysis of authorization problems, including CDS view level
• FLP Content Manager (/UI2/FLPCM_CUST): Checking the Fiori catalogues and their configuration
• PFCGUPDATEROLEMENU: Matching the catalogues with authorization roles
• Profile generation and user matching: Ensuring consistency

Fiori Apps Library: An indispensable tool

The Fiori Apps Library is invaluable at every stage of the analysis. It provides detailed information on prerequisites, installation requirements, component statuses and service configurations for each Fiori app.

Conclusion

This structured approach makes it possible to systematically isolate and resolve authorization problems. Note that the order of the steps may vary depending on the specific error. Experience plays an important role, but even for experienced experts, this overview can serve as a valuable checklist.

I invite you to download the S/4HANA authorization troubleshooting overview and use it in your daily work. Feedback and suggestions for improvement are explicitly encouraged, as we can all learn from each other.
