• What is the cause and solution for SAP error message RSDS321 - Delta method &1: Only use ' ', FIL0 or FIL1 ?

  The SAP error message RSDS321 typically occurs in the context of DataSources and delta methods in SAP BW (Business Warehouse). This error indicates that the delta method specified for a DataSource is not valid. The message suggests that only specific delta methods ('   ', FIL0, or FIL1) are allowed.
  Cause:
  The error is caused by the configuration of the delta method for a DataSource. The delta method determines how data is extracted from the source system. The valid delta methods are:
  
  '   ': This represents a full data load.
  FIL0: This is used for delta extraction from a DataSource that supports delta.
  FIL1: This is used for delta extraction from a DataSource that supports delta with a different mechanism.
  
  If a different or invalid delta method is specified, the system will throw the RSDS321 error.
  Solution:
  To resolve the RSDS321 error, follow these steps:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the SAP BW system (transaction code RSA1).
  Navigate to the DataSource in question and check its delta method settings.
  
  
  
  Set the Correct Delta Method:
  
  If the DataSource is intended for delta extraction, ensure that it is set to either FIL0 or FIL1.
  If you want to perform a full load, set the delta method to '   ' (blank).
  
  
  
  Activate the DataSource:
  
  After making changes to the delta method, make sure to activate the DataSource again.
  
  
  
  Test the DataSource:
  
  After activation, test the DataSource to ensure that it is functioning correctly without errors.
  
  
  
  Check Documentation:
  
  Refer to SAP documentation or notes related to the specific DataSource you are working with to ensure that you are using the correct delta method.
  
  
  
  Related Information:
  
  Delta Methods: Understanding the different delta methods is crucial for effective data extraction in SAP BW. Each method has its own use case and implications for data loading.
  SAP Notes: Check for any relevant SAP Notes that might provide additional insights or updates regarding the DataSource or delta methods.
  DataSource Types: Different types of DataSources (e.g., generic, SAP, etc.) may have different requirements for delta methods.
  
  By following these steps, you should be able to resolve the RSDS321 error and configure your DataSource correctly for data extraction.
