FL372 - Details

• The SAP error message FL372, which states "Reference parameters are not allowed in the update task," typically occurs in the context of ABAP programming, particularly when dealing with update function modules. This error indicates that a reference parameter is being used in a context where it is not permitted, specifically within an update task.
  
  Cause:
  
  
  Reference Parameters in Update Tasks: In ABAP, reference parameters (using the REF TO syntax) cannot be used in update function modules. Update function modules are designed to be executed in a separate update task, and reference parameters cannot be passed in this context due to the way the update task handles data.
  
  
  Incorrect Function Module Definition: If a function module is defined with reference parameters and is intended to be called in an update task, it will trigger this error.
  
  
  
  Solution:
  
  
  Change Parameter Types: Modify the function module to use value parameters instead of reference parameters. This means changing the
