• What is the cause and solution for SAP error message RSRTS_CDS145 - Annotated formula for &1: &2 cannot be used (must be based on measure) ?

  The SAP error message RSRTS_CDS145 indicates that there is an issue with the use of an annotated formula in a Core Data Services (CDS) view or a calculation view in SAP BW/4HANA or SAP HANA. Specifically, the error states that the annotated formula cannot be used because it must be based on a measure.
  Cause:
  This error typically occurs when:
  
  Incorrect Formula Definition: The formula you are trying to use is not defined correctly. It may not be based on a measure, which is a requirement for certain types of calculations in SAP BW/4HANA or SAP HANA.
  Data Model Issues: The underlying data model may not have the necessary measures defined, or the formula is referencing fields that are not measures.
  Aggregation Issues: The formula may be attempting to perform an aggregation on a non-measure field, which is not allowed.
  
  Solution:
  To resolve the RSRTS_CDS145 error, you can take the following steps:
  
  
  Check the Formula Definition:
  
  Ensure that the annotated formula is defined correctly and is based on a measure. Review the syntax and the fields being used in the formula.
  If you are using a calculated column, make sure it is defined as a measure.
  
  
  
  Review the Data Model:
  
  Verify that the fields referenced in the formula are indeed measures. You can do this by checking the data model in the SAP HANA Studio or the SAP BW Modeling Tools.
  If necessary, create or modify the measures in your data model to ensure they are available for use in the formula.
  
  
  
  Adjust Aggregation Logic:
  
  If your formula involves aggregation, ensure that it is applied to a measure. You may need to adjust the logic to ensure that only measures are being aggregated.
  
  
  
  Test the Formula:
  
  After making the necessary adjustments, test the formula again to see if the error persists. You can do this by executing the query or the calculation view where the formula is used.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for detailed information on how to define measures and annotated formulas correctly. This can provide insights into best practices and common pitfalls.
