  The SAP error message /PF1/MSG_CONV_XML157 typically indicates a mismatch in the expected number of occurrences of a field in an XML structure during data conversion or processing. This error often arises when the data being processed does not conform to the expected schema or structure defined in the XML.
  Cause:
  
  Schema Mismatch: The XML data being processed does not match the expected schema. For example, if a field is expected to have a certain number of occurrences (like a list of items), but the actual data has a different number, this error will occur.

  Solution:
  
  Check XML Structure: Review the XML data being processed to ensure it matches the expected structure. Validate the number of occurrences of the specified field against the schema definition.
  Adjust Data: If the data is incorrect, modify the source data to ensure it has the correct number of occurrences for the specified field.
  Review Mapping Configuration: If you are using a mapping tool or transformation logic, check the configuration to ensure it correctly defines the expected occurrences of fields.
  Debugging: Use debugging tools or logs to trace the data flow and identify where the mismatch occurs. This can help pinpoint the exact location in the data processing where the error arises.
  Consult Documentation: Refer to SAP documentation or the specific module documentation related to the XML processing to understand the expected structure and requirements.
