• What is the cause and solution for SAP error message RSDS266 - Delta field is not flagged for transfer ?

  The SAP error message RSDS266, which states "Delta field is not flagged for transfer," typically occurs in the context of data extraction from a source system to a data warehouse (like SAP BW). This error indicates that a field that is expected to be part of the delta extraction process is not configured correctly in the source system.
  Cause:
  
  Field Configuration: The field in question is not marked as a delta field in the DataSource configuration. Delta fields are those that are tracked for changes, allowing for incremental data loads rather than full loads.
  DataSource Settings: The DataSource may not be set up correctly to include the necessary fields for delta extraction.
  Change Log: The change log for the data source may not be properly configured or may not exist, which is necessary for delta extraction.
  Field Type: The field may not be of a type that supports delta extraction (e.g., certain calculated fields or non-key fields).
  
  Solution:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the source system (transaction code RSA1 in BW).
  Verify that the field is marked for delta extraction. You can do this by checking the field properties in the DataSource definition.
  If the field is not marked, you may need to adjust the DataSource settings to include it.
  
  
  
  Modify the DataSource:
  
  If necessary, modify the DataSource to include the field as a delta field. This may involve changing the extraction logic or adding the field to the change log.
  After making changes, you may need to regenerate the DataSource.
  
  
  
  Check Change Log:
  
  Ensure that the change log is active and properly configured for the DataSource. This is essential for delta extraction to work.
  
  
  
  Reinitialize Delta:
  
  If changes are made, you may need to reinitialize the delta process. This typically involves performing a full load followed by a delta load.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific DataSource you are working with, as there may be additional considerations or known issues.
  
  
  
  Related Information:
  
  Transaction Codes: Use RSA1 for Data Warehousing Workbench, RSD1 for DataSource maintenance, and RSA3 for testing DataSources.
  SAP Notes: Check for relevant SAP Notes that may address specific issues related to your DataSource or the error message.
  Delta Mechanism: Understand the delta mechanism in SAP BW, including how it works and the requirements for fields to be included in delta extraction.
  
  By following these steps, you should be able to resolve the RSDS266 error and ensure that the necessary fields are correctly configured for delta extraction.
