  Causes:
  
  Data Source Issues: The data source may not be properly configured or may have been changed in the source system.
  Delta Queue Problems: The delta queue may be inconsistent or may have entries that are not processed correctly.
  Authorization Issues: The user executing the delta extraction may not have the necessary authorizations to access the data.
  Technical Issues: There may be technical issues in the source system or in the BW system that prevent the delta extraction from completing successfully.

  Network Issues: Connectivity problems between the source system and the BW system can also lead to this error.
  
  Solutions:
  
  Check Data Source Configuration: Verify that the data source is correctly configured in the BW system. Ensure that the extraction settings are correct and that the data source is active.
  Monitor Delta Queue: Use transaction codes like RSA7 to monitor the delta queue. Check for any inconsistencies or entries that need to be processed. If necessary, you can reset the delta queue.
  Review Authorizations: Ensure that the user executing the extraction has the necessary authorizations to access the data in the source system.
  Check for Locks: Investigate if there are any locks on the data in the source system that might be preventing the extraction. You can use transaction codes like SM12 to check for locks.
