Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Concurrent Testing: The function module is being tested in another session by the same user or by a different user.
  Session Locking: SAP locks the function module for testing to prevent data inconsistency or conflicts that may arise from simultaneous testing.
  
  Solutions:
  
  
  Check Active Sessions: 
  
  Verify if you have multiple sessions open in SAP. If so, close the session that is currently testing the function module.
  If another user is testing the function module, you may need to wait until they finish.
  
  
  
  Use Transaction Codes:
  
  If you are using transaction codes like SE37 (Function Builder) or SE80 (Object Navigator), ensure that you are not in the test mode of the function module in another session.
  
  
  
  Log Off Other Sessions: 
  
  If you have access, you can log off other sessions that might be using the function module. This can be done through transaction code SM04 (User Overview) or SM50 (Process Overview).
  
  
  
  Contact Administrator: 
  
  If you are unable to identify the session or user that is testing the function module, contact your SAP system administrator for assistance. They can help identify and resolve the issue.
  
  
  
  Wait and Retry: 
  
  If the function module is being tested by another user, you may need to wait until they complete their testing before you can proceed.
  
  
  
  Related Information:
