  Cause:
  
  Incorrect Attribute Assignment: The InfoObject you are trying to use as an attribute is not defined as an attribute of the reference InfoObject in the data model.

  Rebuild the Data Model:
  
  If the error persists, consider rebuilding the data model or InfoProvider that is causing the issue. This may involve re-creating the InfoProvider or reassigning attributes.
  
  
  
  Check for Transport Issues:
