• What is the cause and solution for SAP error message FM_EXPLAIN019 - You are not allowed to call this program directly ?

  The SAP error message FM_EXPLAIN019 ("You are not allowed to call this program directly") typically occurs when a program or function module is being executed in a way that is not permitted by its design. This is often due to the program being intended for use only as part of a larger process or through specific transaction codes.
  Cause:
  
  Direct Execution: The program or function module is being executed directly from the command field or through a custom transaction, rather than through the intended transaction or interface.
  Authorization Issues: The user may not have the necessary authorizations to execute the program directly.
  Program Design: The program may be designed to be called only by other programs or function modules, and not intended for direct execution.
  
  Solution:
  
  Use the Correct Transaction: Instead of executing the program directly, find the appropriate transaction code that is meant to call the program. This is often the recommended approach.
  Check Authorizations: Ensure that the user has the necessary authorizations to execute the program. This can be done by checking the user's roles and authorizations in the SAP system.
  Review Program Documentation: Check the documentation or comments within the program to understand how it is intended to be used. This may provide insights into the correct usage.
  Contact SAP Support: If you believe that the program should be callable directly and you have the necessary authorizations, consider reaching out to SAP support for further assistance.
  
  Related Information:

  Debugging: If you have access, you can debug the program to see where the restriction is being enforced, but this should be done with caution and preferably in a development environment.
