• What is the cause and solution for SAP error message CDSUI011 - Selected attribute is already tagged ( Tag Attribute name '&1' ) ?

  The SAP error message CDSUI011 indicates that there is an issue with the selection of attributes in a Core Data Services (CDS) view or a related UI component. Specifically, it means that the attribute you are trying to select has already been tagged or marked for use in the context of the CDS view or the UI component.
  Cause:
  
  Duplicate Tagging: The attribute you are trying to select has already been tagged in the CDS view or UI component. This can happen if the same attribute is being used multiple times in the same context.
  Incorrect Configuration: There may be a misconfiguration in the CDS view or the UI component that leads to the same attribute being tagged more than once.
  Modeling Errors: Errors in the underlying data model or the way the CDS view is defined can also lead to this issue.
  
  Solution:
  
  Review the CDS View: Check the definition of the CDS view to see if the attribute is already tagged. If it is, you may need to remove the duplicate tagging or adjust the view definition.
  Modify the UI Component: If the error occurs in a UI component, review the configuration of the UI element to ensure that the attribute is not being referenced multiple times.
  Check for Inheritance: If the attribute is inherited from a parent view or entity, ensure that it is not being re-tagged in the child view or component.
  Use Unique Tags: Ensure that each attribute is tagged uniquely within the context of the CDS view or UI component to avoid conflicts.
