• What is the cause and solution for SAP error message RSDS329 - DataSource &1(&2) does not support generic delta on SDI change time ?

  The SAP error message RSDS329 indicates that a specific DataSource does not support generic delta extraction based on the change time when using SAP Data Intelligence (SDI). This typically occurs when you are trying to set up a delta extraction for a DataSource that is not configured to handle such operations.
  Cause:
  
  DataSource Configuration: The DataSource you are trying to use may not be configured to support generic delta extraction. This can happen if the DataSource is not designed to track changes or does not have the necessary fields for change tracking.
  Change Time Field: The DataSource may not have a change time field that can be used for delta extraction. Generic delta extraction relies on a timestamp to identify new or changed records.
  DataSource Type: Some DataSources, especially those that are not based on standard tables or views, may not support delta extraction.
  
  Solution:
  
  Check DataSource Configuration: Review the configuration of the DataSource in the SAP system. Ensure that it is set up to support delta extraction. You may need to consult the documentation for the specific DataSource to understand its capabilities.
  Use Full Load Instead: If the DataSource does not support delta extraction, consider using a full load instead of a delta load. This means you will extract all records every time you run the job, which may not be efficient but will work if delta is not an option.
  Modify DataSource: If possible, modify the DataSource to include a change time field or to enable delta capabilities. This may involve working with your SAP Basis or development team.
  Consult SAP Notes: Check for any relevant SAP Notes that may provide additional information or updates regarding the specific DataSource you are using. SAP Notes can provide fixes or workarounds for known issues.
  
  Related Information:
  
  SAP Data Intelligence Documentation: Review the official SAP Data Intelligence documentation for guidelines on setting up DataSources and understanding delta extraction.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  SAP Support: If the issue persists, consider reaching out to SAP Support for assistance, especially if you believe this is a bug or a limitation that needs to be addressed.
  
  By following these steps, you should be able to address the RSDS329 error and successfully configure your DataSource for the desired extraction method.
