  The SAP error message RSM1168 indicates that there is an issue with calling a function module (FM) in a source system from SAP BW (Business Warehouse). This error typically arises when there are problems with the data extraction process, particularly when conversion exits are involved.
  Cause:
  
  Function Module Not Available: The specified function module (&1) may not be available in the source system (&2). This can happen if the function module is not defined or has been deleted.
