• What is the cause and solution for SAP error message R8680 - No changes to DataSource &1 ?

  The SAP error message R8680 "No changes to DataSource &1" typically occurs in the context of data extraction processes, particularly when working with SAP BW (Business Warehouse) or SAP BI (Business Intelligence). This message indicates that there are no changes detected in the specified DataSource, which can lead to issues when trying to load or extract data.
  Cause:
  
  No New Data: The most common reason for this error is that there are no new records or changes in the source system for the specified DataSource since the last extraction.
  Delta Mechanism: If you are using a delta mechanism for data extraction, it may indicate that the delta queue is empty, meaning there are no new changes to be extracted.
  Incorrect Configuration: There might be a configuration issue with the DataSource or the extraction process that prevents it from recognizing changes.
  DataSource Activation: The DataSource may not be properly activated or may have been deactivated in the source system.
  Time Interval: The time interval for the delta extraction may not have been set correctly, leading to no new data being available for extraction.
  
  Solution:
  
  Check Source System: Verify that there are indeed new records or changes in the source system for the DataSource in question. You can do this by querying the source tables directly.
  Delta Queue: If using delta extraction, check the delta queue in the source system to ensure it is populated with new changes. You can use transaction codes like RSA7 to monitor the delta queue.
  Reinitialize Delta: If the delta queue is empty and you expect changes, you may need to reinitialize the delta for the DataSource. This involves performing a full load to reset the delta mechanism.
  DataSource Activation: Ensure that the DataSource is activated in the source system. You can check this in the DataSource maintenance transaction (e.g., RSA1).
  Check Extraction Settings: Review the extraction settings in the BW system to ensure they are configured correctly. This includes checking the extraction method and any filters applied.
  Time Interval: Adjust the time interval for the delta extraction if necessary to ensure it captures the expected changes.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1 (Data Warehousing Workbench), RSA7 (Delta Queue Monitor), and RSC3 (DataSource Monitor).
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to your version of SAP BW or the DataSource in question.
  Documentation: Review SAP documentation for best practices on data extraction and handling DataSources, especially regarding delta loads.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis or BW team for further investigation.
