DeepEntity or ChangeSet question

[Angelo_Ab]

Hi,

I would like to know if there is a way to do the following OData Calls scenario.

I have a Parent Header Entity with 3 Childs (Items, Conditions, Texts).

In my flow during acquisition of an Order, before saving the Order, the user can simulate Price Conditions with a Button.

In this phase, I need to call Backend sending Header and Items data inserted from the user.

The backend with Header and Items Data shoud send back calculated Price Conditions(1..*), Gift Items(1..*), Automatic Texts(1..*).

There is a way to do this without save any information on Backend ?

I tried to use ChangeSet but, I do not receive any response (similar problem explained in this question: SAP MDK Changeset Response). Furthermore, as explained, I can't read the data after ChangeSet call because the data was not saved in the Backend in this phase.

I tried also to check the way to use DeepEntity calls but I do not understand how to do all the calls, send Header and Items, and receive Conditions, Items and texts, like explained above.

I would like to avoid saving local information in the Backend that I have to read after the request calls.

Any suggestion ?

Thanks.

When you say "In this phase, I need to call Backend sending Header and Items data inserted from the user." what does that mean?  Are you calling a function in your OData service to return the Price Conditions or how are you passing the data to your Pricing Condition calculator?

Hi Bill,

we are using an OData V2 and all data is passed through a ChangeSet call.

Unfortunately ChangeSet does not return response than we tried a workaround where we send data to backend in a specialized entity through a simple CreateEntity with Header and Item attribute passed in JSON format, Backend then send back calculated JSONs.

You mention the function, i never used it before, do you have an example ? Thanks.
