  The SAP error message SAI_MAPPING120 indicates that there is a missing parameter definition in a multi-mapping scenario. This typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when you are working with mappings, especially when using graphical or XSLT mappings.

  Validate Source and Target Structures:
  
  Ensure that the source and target message types are correctly defined and that they match the expected structures in the mapping.
  If there are changes in the message types, update the mapping accordingly.
  
  
  
  Test the Mapping:
  
  After making the necessary adjustments, test the mapping with sample data to ensure that it works as expected.
