• What is the cause and solution for SAP error message MDG_IDM_TOOLS029 - Key mapping extractor does not support delta extraction ?

  The SAP error message MDG_IDM_TOOLS029 indicates that the key mapping extractor you are trying to use does not support delta extraction. This typically occurs in the context of SAP Master Data Governance (MDG) when you are attempting to extract data changes (delta) for key mapping but the extractor is not configured to handle such operations.
  Cause:
  
  Extractor Limitation: The key mapping extractor you are using is designed only for full data extraction and does not have the capability to track changes or deltas.
  Configuration Issues: The extractor may not be properly configured to support delta extraction, or the necessary settings may not have been enabled.
  Version Compatibility: The version of the extractor or the underlying data model may not support delta extraction.
  
  Solution:
  
  Use Full Extraction: If delta extraction is not supported, you may need to perform a full extraction instead. This means extracting all relevant data rather than just the changes.
  Check Configuration: Review the configuration of the key mapping extractor in the SAP system. Ensure that it is set up correctly and that any necessary settings for delta extraction are enabled.
  Consult Documentation: Refer to the SAP documentation for the specific extractor you are using. This may provide insights into its capabilities and limitations regarding delta extraction.
  Update Extractor: If possible, check if there is an updated version of the extractor that supports delta extraction. You may need to apply patches or updates to your SAP system.
  Custom Development: If delta extraction is a critical requirement and the standard extractor does not support it, consider developing a custom extractor that can handle delta changes.
