• What is the cause and solution for SAP error message RSAU177 - No source InfoObject was allocated to InfoObject & ?

  The SAP error message RSAU177 "No source InfoObject was allocated to InfoObject &" typically occurs in the context of SAP BW (Business Warehouse) when there is an issue with the data source or InfoObject configuration. This error indicates that the system cannot find a source InfoObject that is supposed to be linked to the target InfoObject.
  Cause:
  
  Missing Source InfoObject: The target InfoObject does not have a source InfoObject assigned to it. This can happen if the InfoObject was created without properly linking it to a data source.
  Incorrect Configuration: The configuration settings for the InfoObject may be incorrect or incomplete, leading to the absence of a source InfoObject.
  Transport Issues: If the InfoObject was transported from one system to another (e.g., from development to production), the source InfoObject may not have been included in the transport.
  Data Model Changes: Changes in the data model or InfoObject structure may have led to the disconnection between the source and target InfoObjects.
  
  Solution:
  
  
  Check InfoObject Settings:
  
  Go to the InfoObject maintenance transaction (e.g., RSA1) and check the settings for the target InfoObject.
  Ensure that a source InfoObject is assigned correctly.
  
  
  
  Assign Source InfoObject:
  
  If the source InfoObject is missing, you may need to create or assign an existing InfoObject as the source.
  In the InfoObject maintenance screen, navigate to the "Source" tab and assign the appropriate source InfoObject.
  
  
  
  Review Data Source Configuration:
  
  Check the data source configuration to ensure that it is correctly set up to provide data to the target InfoObject.
  Make sure that the data source is active and properly configured.
  
  
  
  Transport Check:
  
  If the issue arose after a transport, verify that all necessary objects were included in the transport request.
  If needed, re-transport the missing InfoObjects.
  
  
  
  Rebuild Data Model:
  
  If the InfoObject is part of a larger data model, consider rebuilding or reconfiguring the data model to ensure all components are correctly linked.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific version of SAP BW you are using for any additional troubleshooting steps or known issues.
