The error message provides details about the specific field and value that are causing the issue.
  Cause:
  
  
  Incorrect Mapping Configuration: The most common cause is that the mapping configuration for the input parameters is incorrect. This could be due to a mismatch between the expected data type or structure and the actual data being sent.
  
  
  Missing or Incorrect Data: The input data may be missing required fields or may contain values that do not conform to the expected format or constraints.
  
  
  Namespace Issues: If the service interface or mapping is using different namespaces, it can lead to mapping errors.
  
  
  Version Mismatch: If there are different versions of the service interface or mapping being used, it can lead to inconsistencies.
  
  
  Data Transformation Errors: If there are transformations applied to the data that are not correctly defined, it can lead to errors during the mapping process.
  
  
  Solution:
  
  
  Check Mapping Configuration: Review the mapping configuration in the Integration Directory or the mapping program to ensure that all input parameters are correctly defined and mapped.
  
  
  Validate Input Data: Ensure that the data being sent to the service matches the expected format and contains all required fields. You can use tools like the SAP PI/PO message monitoring to inspect the payload.
  
  
  Review Namespaces: Ensure that the namespaces used in the service interface and mapping are consistent and correctly defined.
  
  
  Test with Sample Data: Use sample data that is known to work to test the mapping. This can help isolate whether the issue is with the data being sent or the mapping itself.
  
  
  Check for Updates: If you are using a third-party mapping tool or custom mapping logic, ensure that it is up to date and compatible with the current version of SAP.
  
  
  Debugging: If the issue persists, consider enabling debugging for the mapping process to get more detailed error messages that can help identify the root cause.
