• What is the cause and solution for SAP error message RSDME174 - Only dimensions of a query can be a key ?

  The SAP error message RSDME174, "Only dimensions of a query can be a key," typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when you are trying to use a characteristic or an object that is not a dimension of a query as a key figure or in a context where it is not allowed.
  Cause:
  This error usually arises due to one of the following reasons:
  
  
  Incorrect Query Design: You may have attempted to use a non-dimension characteristic as a key figure in your query definition. In SAP BW, key figures are typically numerical values that can be aggregated, while dimensions are used to slice and dice the data.
  
  
  Hierarchy Issues: If you are trying to use a characteristic that is part of a hierarchy or is not defined as a dimension in the query, it can lead to this error.
  
  
  Data Model Configuration: The underlying data model may not be correctly configured, leading to inconsistencies in how dimensions and key figures are defined.
  
  
  Solution:
  To resolve the RSDME174 error, you can take the following steps:
  
  
  Check Query Definition:
  
  Open the query in the Query Designer.
  Ensure that all key figures are defined correctly and that you are not trying to use a non-dimension characteristic as a key figure.
  
  
  
  Review Characteristics:
  
  Verify that the characteristics you are using in the query are defined as dimensions. You can do this by checking the InfoObject settings in the SAP BW system.
  
  
  
  Adjust Data Model:
  
  If necessary, adjust the data model to ensure that the characteristics and key figures are correctly defined. This may involve modifying the InfoCube or DataStore Object (DSO) to ensure that the dimensions are set up properly.
  
  
  
  Rebuild the Query:
  
  If the issue persists, consider rebuilding the query from scratch, ensuring that you only include valid dimensions and key figures.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for more detailed guidance on query design and the specific characteristics of your BW version.
  
  
  
  Related Information:
