• What is the cause and solution for SAP error message ESH_CDS_VAL011 - Field &1 of view &2 is a grouped field & &3 is missing in select list ?

  The SAP error message ESH_CDS_VAL011 indicates that there is an issue with a Core Data Services (CDS) view where a grouped field is being referenced, but the corresponding field is missing from the select list. This typically occurs in the context of SAP HANA or when working with CDS views in the SAP Business Technology Platform.
  Cause:
  The error arises when:
  
  You have a grouped field in your CDS view (e.g., a field that is part of a GROUP BY clause).
  The field that is being grouped is not included in the SELECT statement of the CDS view.
  This is a requirement in SQL: when you group by a field, all other fields in the SELECT clause must either be aggregated or included in the GROUP BY clause.
  
  Solution:
  To resolve this error, you need to ensure that all fields that are part of the grouping are included in the SELECT statement. Here are the steps to fix the issue:
  
  
  Identify the Grouped Field: Check the error message for the specific field (&1) and the view (&2) that is causing the issue.
  
  
  Modify the CDS View:
  
  Open the CDS view definition in the ABAP Development Tools or the relevant environment.
  Ensure that the grouped field is included in the SELECT list. If it is not, add it to the SELECT clause.
  Alternatively, if you do not need the field in the output, you can remove it from the GROUP BY clause.
  
  
  
  Check Aggregation: If you are using other fields in the SELECT statement that are not part of the GROUP BY, make sure they are aggregated (e.g., using SUM, COUNT, AVG, etc.).
  
  
  Activate the CDS View: After making the necessary changes, activate the CDS view to apply the modifications.
  
  
  Test the View: Execute the view to ensure that the error is resolved and that the output is as expected.
