• What is the cause and solution for SAP error message EC899 - Function is in use ?

  The SAP error message EC899, which states "Function is in use," typically occurs when you attempt to make changes to a function module, function group, or other related objects that are currently being used or locked by another process or user. This can happen in various scenarios, such as when trying to delete or modify a function module that is still being referenced in the system.
  Causes:
  
  Active Sessions: The function is being used in an active session or transaction.
  Locks: The function module is locked by another user or process.
  Dependencies: Other objects (like programs, function groups, or classes) are dependent on the function you are trying to modify.
  Transport Requests: The function might be part of a transport request that is currently being processed.
  
  Solutions:
  
  
  Check Active Sessions: Use transaction code SM04 to check for active user sessions. If you find a session using the function, you may need to ask the user to log off or close the session.
  
  
  Release Locks: Use transaction code SM12 to check for locks on the function. If you find a lock that is no longer needed, you can delete it (ensure you have the necessary authorizations and that it is safe to do so).
  
  
  Review Dependencies: Check for any dependent objects that might be using the function. You can use transaction code SE80 or SE37 to analyze dependencies.
  
  
  Transport Management: If the function is part of a transport request, ensure that the transport is not currently being processed. You may need to wait until the transport is completed.
