We used RAP to define CDS and root entities, created BO, and bound services.
But..There was a problem trying to change the table in the list object to Analytical table to match the requirements and assign the sum and subtotal of the amount fields.
In general, the app does not work because the default aggregation : #sum, which was written based on segw, is assigned.
The error message indicating that "aggregation function assign to transaction view is not possible."
How can I achieve my requirements?
After simply searching the SCN, I found that it provides a service protocol for analysis called "InA" in the RAP.
Do I have to make use this? Is there a simpler way or alternative?
