• What is the cause and solution for SAP error message EAN_UCC094 - Incorrect interface assignment in function module &1 ?

  The SAP error message EAN_UCC094, which states "Incorrect interface assignment in function module &1," typically indicates that there is a mismatch in the parameters or interface definitions of a function module being called. This can occur in various scenarios, such as when the function module is being invoked with incorrect parameters or when there are changes in the function module's interface that have not been reflected in the calling program.
  Causes:
  
  Parameter Mismatch: The calling program is passing parameters that do not match the expected parameters of the function module.
  Changes in Function Module: The function module's interface has been changed (e.g., parameters added, removed, or modified) after the calling program was developed.
  Incorrect Function Module Call: The function module is being called in a way that does not conform to its defined interface.
  Transport Issues: If the function module was transported from one system to another, there may be inconsistencies in the interface definitions.

  Check for Transport Issues:
  
  If the function module was recently transported, ensure that all related objects and dependencies were also transported correctly. Check for any inconsistencies between the development and production environments.
  
  
  
  Debugging:
  
  Use the debugger to trace the execution of the program and identify where the incorrect parameters are being passed to the function module.
