  The SAP error message FL051, which states "Reassign/copy of NON-EXIT function modules to EXIT group not allowed," typically occurs when there is an attempt to reassign or copy a function module that is not defined as an "EXIT" function module into an EXIT group. This is a restriction in SAP to ensure that only appropriate function modules are assigned to EXIT groups.
  Cause:
  
  Function Module Type: The function module you are trying to reassign or copy is not defined as an EXIT function module. EXIT function modules are specifically designed to allow enhancements in SAP without modifying the original code.

  Solution:
  
  Check Function Module Type: Verify the type of the function module you are trying to reassign. You can do this by navigating to the function module in transaction SE37 or SE80 and checking its attributes.
  Use Correct Function Module: If you need to enhance functionality, ensure you are using a function module that is specifically designed as an EXIT. You can find these in the SAP enhancement framework.
  Create a New EXIT Function Module: If you need to implement custom logic, consider creating a new EXIT function module that adheres to the EXIT function module standards.
  Consult Documentation: Review SAP documentation or notes related to the specific enhancement or EXIT you are working with to ensure compliance with SAP standards.
