  The SAP error message GHO_PE_BO020, which states "Aggregate &1 already exists," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when you are trying to create an aggregate that already exists in the system. This can happen during the process of data modeling or when managing aggregates in the BW system.
  Cause:
  
  Duplicate Aggregate: The most common cause of this error is that an aggregate with the same name or identifier already exists in the system.
  Incorrect Naming: There might be a naming conflict due to similar names or identifiers.

  Alternatively, you can modify the existing aggregate if it needs to be updated rather than creating a new one.
  
  
  
  Check for Transport Issues: 
  
  If you are working in a development environment and transporting objects to a production environment, ensure that the transport does not contain duplicates.
