• What is the cause and solution for SAP error message PG157 - Incorrect return code &1 for user exit ?

  The SAP error message PG157, which states "Incorrect return code &1 for user exit," typically occurs when a user exit (a custom enhancement point in SAP) returns an unexpected return code during processing. This can happen in various scenarios, particularly in the context of sales and distribution (SD) or other modules where user exits are commonly used.
  Cause:
  
  Incorrect Return Code: The user exit is expected to return a specific return code (usually 0 for success). If it returns a different code (like 1, 2, etc.), the system will trigger this error.
  Custom Code Issues: If there is custom code in the user exit that has not been properly implemented or tested, it may lead to unexpected return codes.
  Configuration Issues: Sometimes, the configuration settings related to the user exit may not be set up correctly, leading to the error.
  Data Issues: The data being processed may not meet the expected criteria, causing the user exit to fail.
  
  Solution:
  
  Check User Exit Implementation: Review the code in the user exit to ensure that it is returning the correct return code. The return code should typically be 0 for success.
  Debugging: Use the SAP debugger to step through the user exit code to identify where the incorrect return code is being generated.
