• What is the cause and solution for SAP error message RSAR658 - No changes to InfoSources (&) found ?

  The SAP error message RSAR658 "No changes to InfoSources (&) found" typically occurs in the context of SAP BW (Business Warehouse) when you are trying to activate or update an InfoSource, and the system does not detect any changes that require activation. This can happen for several reasons, and understanding the cause can help in resolving the issue.
  Causes:
  
  
  No Changes Made: The most straightforward reason is that there have been no actual changes made to the InfoSource since the last activation. This can happen if you are trying to activate an InfoSource that has not been modified.
  
  
  Transport Issues: If the InfoSource was transported from another system, there might be inconsistencies or issues with the transport that prevent the system from recognizing changes.
  
  
  Buffer Issues: Sometimes, the system's buffer may not be updated correctly, leading to discrepancies in what the system recognizes as changes.
  
  
  Incorrect InfoSource: You might be trying to activate an InfoSource that does not exist or is not correctly defined in the system.
  
  
  Solutions:
  
  
  Check for Changes: Verify if any changes were actually made to the InfoSource. If not, there is no need to activate it.
  
  
  Recheck Transport: If the InfoSource was transported, ensure that the transport was successful and that all necessary objects were included.
  
  
  Clear Buffer: You can try to clear the buffer for the InfoSource. This can sometimes resolve issues where the system is not recognizing changes. You can do this by using transaction codes like RSBTRAC or RSBCT to check and clear the buffer.
  
  
  Recreate the InfoSource: If the InfoSource is not functioning as expected, consider recreating it. This can help resolve any underlying issues that may not be immediately apparent.
  
  
  Check for Dependencies: Ensure that all dependent objects (like DataSources, InfoObjects, etc.) are also correctly defined and activated.
  
  
  Consult Logs: Check the system logs for any additional error messages or warnings that might provide more context about the issue.
  
  
  Related Information:
