• What is the cause and solution for SAP error message RSQU018 - Delta has not been set in delta queue ?

  The SAP error message RSQU018, which states "Delta has not been set in delta queue," typically occurs in the context of SAP's data extraction processes, particularly when working with SAP BW (Business Warehouse) or SAP HANA. This error indicates that the delta queue for a specific data source has not been properly initialized or updated, which can prevent data from being extracted correctly.
  Causes:
  
  Delta Queue Initialization: The delta queue may not have been initialized properly. This can happen if the initial load of data was not completed successfully.
  Data Source Configuration: The data source may not be configured correctly, leading to issues in capturing delta changes.
  Replication Issues: There may be issues with the replication of data from the source system to the BW system, causing the delta queue to be empty.
  Data Extraction Process: The data extraction process may not have been executed correctly, or there may be issues with the extraction job.
  System Errors: Temporary system errors or inconsistencies in the source system can also lead to this error.
  
  Solutions:
  
  Check Delta Queue Status: Use transaction code RSA7 to check the status of the delta queue. Ensure that there are entries in the delta queue for the data source in question.
  Reinitialize Delta: If the delta queue is empty, you may need to reinitialize the delta for the data source. This typically involves performing a full load followed by a delta load.
  
  Go to the data source in the source system and perform a full load.
  After the full load, set the delta queue again.
  
  
  Check Data Source Configuration: Verify that the data source is configured correctly in the source system. Ensure that the extraction settings are appropriate and that the data source is active.
  Monitor Data Extraction Jobs: Check the status of the data extraction jobs in the BW system. Ensure that they are running without errors and that they are configured to capture delta changes.
  Check for System Errors: Look for any system errors or inconsistencies in the source system that may be affecting the delta queue. Resolve any underlying issues that may be causing the problem.
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
