• What is the cause and solution for SAP error message CFD_REGISTRY_CHECK115 - Group By flag must be set for CDS View with aggregation via Group By ?

  The SAP error message CFD_REGISTRY_CHECK115 indicates that there is an issue with a Core Data Services (CDS) view that involves aggregation. Specifically, it states that the "Group By" flag must be set for a CDS view that uses aggregation via the GROUP BY clause.
  Cause:
  This error typically occurs when you are trying to create or execute a CDS view that includes aggregate functions (like SUM, COUNT, etc.) without properly defining the grouping criteria. In a CDS view, when you use aggregation, you must specify how the data should be grouped. If the "Group By" flag is not set, the system cannot determine how to aggregate the data correctly, leading to this error.
  Solution:
  To resolve this error, you need to ensure that your CDS view is correctly defined with the necessary grouping. Here are the steps to do that:
  
  
  Check the CDS View Definition: Open the CDS view in the ABAP Development Tools (ADT) or the relevant editor.
  
  
  Add Group By Clause: Ensure that you have a GROUP BY clause in your CDS view definition. This clause should include all the non-aggregated fields that you want to group your results by.
  Example:
  define view Z_MY_CDS_VIEW
  as select from my_table
  {
      key field1,
      key field2,
      sum(field3) as total_field3
  }
  group by field1, field2
  
  
  Set the Group By Flag: If you are using the CDS view in a context where the Group By flag needs to be explicitly set (like in certain annotations or configurations), make sure to set it accordingly.
  
  
  Check for Annotations: If you are using annotations in your CDS view, ensure that they are correctly defined and that they do not conflict with the aggregation logic.
  
  
  Activate the CDS View: After making the necessary changes, activate the CDS view to apply the modifications.
  
  
  Related Information:
  
  CDS Views: Core Data Services (CDS) is a framework for defining semantically rich data models in SAP. It allows for the creation of views that can include complex logic, including aggregations.
  Aggregation in CDS: When using aggregation in CDS views, it is essential to understand how to use the GROUP BY clause effectively. All fields that are not part of an aggregate function must be included in the GROUP BY clause.
  SAP Documentation: For more detailed information, refer to the official SAP documentation on CDS views and aggregation, which provides guidelines and best practices.
  
  By following these steps and ensuring that your CDS view is correctly defined, you should be able to resolve the CFD_REGISTRY_CHECK115 error.
