• What is the cause and solution for SAP error message UG166 - BWGEN: & & & not saved because DIOB & will be deleted ?

  The SAP error message UG166 BWGEN indicates that a certain object (often a DataSource or InfoObject) is not being saved because it is linked to a DataSource that is marked for deletion. This typically occurs in the context of SAP BW (Business Warehouse) when you are trying to activate or save changes to an object that has dependencies on another object that is no longer valid or is set to be deleted.
  Cause:
  
  Dependency on Deleted Object: The object you are trying to save has dependencies on a DataSource or InfoObject that is marked for deletion.
  Inconsistent State: The system is in an inconsistent state where the object you are working on cannot exist without the referenced object.
  Transport Issues: If you are working in a transport environment, there may be issues with the transport requests that affect the status of the objects.
  
  Solution:
  
  Check Dependencies: Identify the object that is causing the issue (the one marked for deletion). You can do this by checking the object’s properties or dependencies in the SAP BW modeling tools.
  Restore or Delete: 
  
  If the object marked for deletion is still needed, you may need to restore it from the deletion status.
  If it is no longer needed, ensure that all dependencies are removed from the object you are trying to save.
  
  
  Re-activate Objects: After resolving the dependency issue, try to re-activate or save the object again.
  Check Transport Requests: If you are in a transport environment, ensure that all relevant transport requests are correctly released and imported.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of BW you are using for any additional troubleshooting steps.
