• What is the cause and solution for SAP error message RSDME853 - Model &1 is attached to inactive/invalid BW DataSource &3 ?

  The SAP error message RSDME853 indicates that a model (typically a BW model) is associated with a DataSource that is either inactive or invalid. This can occur in SAP BW (Business Warehouse) when there are issues with the DataSource that the model relies on for data extraction.
  Cause:
  
  Inactive DataSource: The DataSource that the model is linked to is not active. This can happen if the DataSource has been deactivated for maintenance or other reasons.
  Invalid DataSource: The DataSource may have been deleted or is not properly configured, leading to it being considered invalid.
  Changes in DataSource: If there have been changes to the DataSource (like changes in structure or fields) that are not reflected in the model, it can lead to this error.
  Transport Issues: If the DataSource was transported from one system to another and there were issues during the transport, it may not be valid in the target system.
  
  Solution:
  
  
  Activate the DataSource:
  
  Go to the DataSource in the SAP BW system (transaction code RSA1).
  Check the status of the DataSource. If it is inactive, activate it.
  
  
  
  Check DataSource Configuration:
  
  Ensure that the DataSource is correctly configured and that all necessary fields and structures are in place.
  If the DataSource has been modified, ensure that the model is updated accordingly.
  
  
  
  Validate the DataSource:
  
  Use transaction RSA3 to test the DataSource and ensure it is functioning correctly.
  If the DataSource is invalid, you may need to recreate it or fix any issues that are causing it to be invalid.
  
  
  
  Check for Transport Issues:
  
  If the DataSource was recently transported, check the transport logs for any errors.
  If necessary, re-transport the DataSource or manually correct any issues.
  
  
  
  Reassign the Model:
  
  If the DataSource is no longer needed, consider reassigning the model to a different, valid DataSource.
