• What is the cause and solution for SAP error message RSDHA039 - Technical attribute '&1' must not be mapped or selected ?

  The SAP error message RSDHA039 indicates that a technical attribute is being incorrectly mapped or selected in a data model, such as an InfoObject or a DataSource. This error typically arises in the context of SAP BW (Business Warehouse) or SAP HANA when working with data modeling and reporting.
  Cause:
  The error occurs when:
  
  A technical attribute (like a key field) is being used in a way that is not allowed. Technical attributes are meant to serve specific purposes and should not be included in certain mappings or selections.
  The attribute is being selected in a query or a data model where it is not permitted, such as in a characteristic or a key figure context.
  There may be a misconfiguration in the InfoObject or the data model that leads to the selection of a technical attribute.
  
  Solution:
  To resolve the RSDHA039 error, you can take the following steps:
  
  
  Review the InfoObject: Check the definition of the InfoObject associated with the technical attribute. Ensure that the attribute is not being incorrectly mapped or selected in the data model.
  
  
  Check Query Design: If the error occurs in a query, review the query design in the Query Designer. Ensure that technical attributes are not included in the selection criteria or in the display of the query.

  Remove Technical Attributes: If you find that a technical attribute is being selected or mapped, remove it from the selection or mapping. Only include attributes that are meant to be used in the context of your data model.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on the use of technical attributes in your version of SAP BW or HANA.
  
  
  Testing: After making the necessary changes, test the data model or query again to ensure that the error is resolved.
