In our project we are extending the item to orders.
Specifically, we are adding attributes to VBAK.
We want to use API_SALES_ORDER_SRV/A_SalesOrder to register data (POST).
(GET could be obtained by extending CDS View)
If I set a value to the extended item and POST it, there is no error.
I feel like it is being ignored.
Do I need to add a process somewhere?
Please let me know folks.
