• What is the cause and solution for SAP error message /SAPCND/MAINTENANCE406 - Only select dimension columns. ?

  The SAP error message /SAPCND/MAINTENANCE406 Only select dimension columns typically occurs in the context of SAP Analytics Cloud (SAC) or SAP BW (Business Warehouse) when you are trying to create a query or a model that includes measures or non-dimension columns in a context where only dimension columns are allowed.
  Cause:
  
  
  Query Design: The error usually arises when you attempt to select or use non-dimension fields (like measures or calculated fields) in a context that only allows dimension fields. This can happen in scenarios such as:
  
  Creating a filter or a hierarchy where only dimension columns are valid.
  Using a dimension in a context that expects only dimension attributes.
  
  
  
  Model Configuration: The model or data source you are working with may be configured to only allow dimension columns in certain areas, leading to this restriction.
  
  
  Solution:
  
  
  Review Your Query/Model: Check the query or model you are working on and ensure that you are only selecting dimension columns where required. Remove any measures or non-dimension fields from the selection.
  
  
  Adjust Filters and Contexts: If you are applying filters or creating hierarchies, ensure that you are using only dimension fields. If you need to include measures, consider how they can be aggregated or calculated after the dimensions are selected.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific tool you are using (e.g., SAP BW, SAC) to understand the limitations and requirements for selecting columns in queries or models.
