• What is the cause and solution for SAP error message CNV_PE_UI803 - Sender structure cannot be assigned to an X-structure parameter ?

  The SAP error message CNV_PE_UI803 indicates that there is an issue with the assignment of a sender structure to an X-structure parameter in a conversion or migration process. This typically occurs in the context of data migration projects, especially when using SAP's tools for data conversion, such as the SAP S/4HANA Migration Cockpit or other data migration tools.
  Cause:
  
  Structure Mismatch: The sender structure does not match the expected format of the X-structure parameter. This could be due to differences in field names, data types, or the number of fields.
  Configuration Issues: There may be configuration issues in the data migration settings that lead to incorrect mapping between the source and target structures.

  Missing Fields: Required fields in the X-structure may be missing from the sender structure, leading to assignment failures.
  
  Solution:
  
  Check Structure Definitions: Review the definitions of both the sender structure and the X-structure. Ensure that they have compatible field names, data types, and structures.
  Adjust Mapping: If you are using a mapping tool, ensure that the mapping between the sender and X-structure is correctly defined. Adjust the mapping as necessary to ensure compatibility.
  Field Compatibility: Ensure that all required fields in the X-structure are present in the sender structure. If any fields are missing, you may need to modify the sender structure or adjust the migration logic.
  Data Type Alignment: Verify that the data types of the fields in both structures are compatible. If there are discrepancies, you may need to convert data types or adjust the structures accordingly.
