• What is the cause and solution for SAP error message RSM2046 - No new data since the last delta update ?

  The SAP error message RSM2046 ("No new data since the last delta update") typically occurs in the context of SAP BW (Business Warehouse) when trying to execute a delta load from a source system to a data target (like an InfoCube or DataStore Object). This message indicates that there are no new records available in the source system since the last delta extraction was performed.
  Cause:
  
  No New Data: The most straightforward cause is that there are genuinely no new records in the source system since the last delta extraction.
  Delta Mechanism Issues: There may be issues with the delta mechanism itself, such as:
  
  The delta queue in the source system is empty.
  The delta extraction process was not set up correctly.
  
  
  Data Selection Criteria: The selection criteria defined in the delta extraction may not match any new records.
  Timing Issues: If the delta extraction is run too frequently, it may not allow enough time for new data to be generated in the source system.
  
  Solution:
  
  Check Source System: Verify that there are indeed new records in the source system. You can do this by querying the relevant tables or using transaction codes in the source system.
  Review Delta Setup: Ensure that the delta extraction is set up correctly. Check the following:
  
  The delta mechanism (e.g., using a delta queue or timestamp).
  The configuration of the InfoSource and DataSource.
  
  
  Monitor Delta Queue: In the source system, check the delta queue to see if it is empty. You can use transaction codes like RSA7 to monitor the delta queue.
  Adjust Extraction Frequency: If the delta extraction is scheduled too frequently, consider adjusting the schedule to allow for more data to accumulate.
  Reinitialize Delta: If you suspect that the delta mechanism is not functioning correctly, you may need to reinitialize the delta for the DataSource. This involves:
  
  Performing a full load to the target.
  Resetting the delta queue.
  
  
  Check for Errors: Look for any errors in the extraction process that may have occurred during previous loads. This can provide insights into why no new data is being extracted.
  
  Related Information:
  
  Transaction Codes:
  
  RSA7: Monitor delta queue.
  RSMO: Monitor the status of the delta process.
  RSPC: Check process chains if delta loads are part of a process chain.
  
  
  Documentation: Refer to SAP Help documentation for detailed information on delta extraction and troubleshooting.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to delta extraction for your version of SAP BW.
  
  By following these steps, you should be able to diagnose and resolve the RSM2046 error effectively.
