  The SAP error message CNV_20310_CHECK025 indicates that there is an issue with the data mapping in a conversion or migration process. Specifically, it means that there is no source data provided for a target field, which results in incomplete mapping. This error typically occurs during data migration projects, especially when using SAP's data migration tools or during the execution of a conversion program.
  Cause:

  Solution:
  
  Check Mapping Configuration: Review the mapping configuration to ensure that all target fields have corresponding source fields defined. Make sure that the mapping is complete and correctly configured.
  Verify Source Data: Ensure that the source system contains the necessary data for the target fields. If data is missing, you may need to extract it from the source system.
  Data Extraction Review: If you suspect that data extraction is the issue, review the extraction logs and processes to identify any errors or missing data.
  Adjust Data Model: If there are inconsistencies between the source and target data models, consider adjusting the mapping or the data model to ensure compatibility.
