• What is the cause and solution for SAP error message RSRTS_CDS152 - Field &1: "display" ignored - only relevant for key fields ?

  The SAP error message RSRTS_CDS152 typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when working with Composite Data Sources (CDS) views or queries. This error indicates that a field in your query or data model is being treated as a non-key field, and the "display" property you are trying to set for it is being ignored because it is only applicable to key fields.
  Cause:
  
  Field Type: The field you are trying to set the "display" property for is not defined as a key field in the underlying data model. In SAP BW, key fields are those that uniquely identify records in a dataset.
  Query Design: The query or data model may have been designed in a way that does not align with the expected key field definitions.
  Data Source Configuration: The configuration of the data source or the way the CDS view is defined may not support the display property for non-key fields.
  
  Solution:
  
  Check Field Definition: Review the definition of the field in the underlying data model or CDS view. Ensure that it is defined as a key field if you want to use the "display" property.
  Modify Query: If the field should not be a key field, consider removing the "display" property from the query or adjusting the query design to align with the data model.
  Adjust Data Source: If you have control over the data source, you may need to modify it to ensure that the relevant fields are correctly defined as key fields if that is appropriate for your use case.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to properly define key fields and their properties in your specific version of SAP BW or SAP HANA.
  
  Related Information:
