How to extend the standard API (A_SalesOrder)

[zyuiti628]

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.

Hi  zyuiti628,

the service API_SalesOrder_SRV is based on an OData service that has been developed with the Service Builder (transaction SEGW).
In an on premise or private cloud system you can try to created redefintion project .

Hi Andre_Fischer,
Is there another way to extend the OData API_SALES_ORDER_SRV/A_SalesOrders? In the Private Cloud on SAP GUI System, the VBAK table is enhanced by appending structure with several Z** fields. How can I display these in the aforementioned OData without having to define a separate API?
