• What is the cause and solution for SAP error message RSRTS_CDS250 - WHEN clause (of CASE) must use measures in context of a formula ?

  The SAP error message RSRTS_CDS250 typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when you are working with a Calculation View or a Composite Provider and you are trying to use a CASE statement in a way that is not compliant with the expected syntax or context.
  Cause:
  The error message indicates that the WHEN clause of the CASE statement is not using measures correctly. In SAP BW or HANA, measures are typically numeric values that can be aggregated, and they must be used in the context of a formula or calculation. The error suggests that the CASE statement is trying to evaluate conditions that do not involve measures or that the measures are not properly defined in the context of the formula.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the CASE Statement Syntax: Ensure that your CASE statement is correctly structured. The syntax should look something like this:
  CASE 
      WHEN <condition1> THEN <result1>
      WHEN <condition2> THEN <result2>
      ...
      ELSE <default_result>
  END
  
  
  Use Measures in the WHEN Clause: Make sure that the conditions in the WHEN clause are based on measures. For example, instead of using a dimension or attribute, use a measure that can be aggregated.
  
  
  Review the Context: Ensure that the CASE statement is being used in a context where measures are valid. If you are using it in a calculated column or a measure, ensure that the context allows for the use of measures.
  
  
  Check Data Types: Ensure that the data types of the measures and the results in the CASE statement are compatible. For example, if your measures are numeric, the results should also be numeric.
  
  
  Test with Simple Conditions: If you are unsure about the conditions, start with simple conditions to see if the error persists. Gradually add complexity to identify the specific part causing the issue.
  
  
  Consult Documentation: If you are still facing issues, refer to the SAP documentation for the specific version you are using, as there may be nuances or updates that affect how CASE statements are handled.
  
  
  Related Information:
  
  SAP BW Documentation: Check the official SAP BW documentation for guidelines on using CASE statements and measures.
