• What is the cause and solution for SAP error message MA793 - Info structure: use of user exits is not supported ?

  The SAP error message MA793 ("Info structure: use of user exits is not supported") typically occurs when there is an attempt to use user exits in the context of an Info structure that does not support them. This can happen in various scenarios, particularly when dealing with the Material Management (MM) module and its associated reporting structures.
  Cause:
  
  Unsupported User Exits: The Info structure you are trying to use does not allow for user exits. This is often the case with standard SAP Info structures that are designed to work with predefined logic and do not permit modifications through user exits.
  Configuration Issues: There may be a misconfiguration in the Info structure settings or the way user exits are implemented.
  Custom Development: If there are custom developments or modifications that attempt to use user exits in a way that is not compatible with the standard Info structure, this error can occur.
  
  Solution:
  
  Check Info Structure Compatibility: Verify if the Info structure you are using supports user exits. You can do this by checking the documentation or SAP notes related to that specific Info structure.
  Remove User Exit Logic: If the Info structure does not support user exits, you will need to remove any user exit logic that is being applied. This may involve modifying the code or configuration that is attempting to use the user exit.
  Use Alternative Approaches: If you need to implement custom logic, consider using alternative methods such as:
  
  BAdIs (Business Add-Ins): These are more flexible and can be used in many cases where user exits are not supported.
  Enhancements: Look for enhancement points in the standard SAP code that allow for custom logic without violating the constraints of the Info structure.
  
  
  Consult SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or solutions for this specific error message.
  
  Related Information:
  
  SAP Documentation: Review the official SAP documentation for the specific Info structure you are working with to understand its limitations and capabilities.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  Debugging: If you have access to the SAP system, you can use debugging tools to trace where the error is occurring and gather more context about the issue.
  
  By following these steps, you should be able to address the MA793 error and implement a solution that aligns with the capabilities of the Info structure you are working with.
