How to upload multiple files simultaneously using create_deep_entity method?

Question

As we all know we can upload files using create_stream method in SAP Gateway(oData).

I want to upload multiple files using Create_Deep_entity along with create_stream method.

How to achieve the same.

Answer 1

In a standard way it is impossible for now. Only one attachment per one call.

However you can try the following trick with DEEP_INSERT method:

1. Place your multi-entity table structure into service model
2. Call service with $expand property, it will call CREATE_DEEP_ENTITY method sequentially
3. Redefine the logic of CREATE_DEEP_ENTITY method
