Create(Create_entity) Method in OData SAP – Part 7

As the name suggests, create method/operation is used to create a new entry or record for the respective entity.

In our previous parts, we are dealing with sales header information (Part 5), in the same fashion, we will create new sales order in the system by using create_entity. And the create operation is type POST method in HTTP

Create_entity takes payload(payload is nothing but a json/xml object) as a request, which is the same as the entity type

You can create a payload either via manually or use the option of “Use as request” in its corresponding get call/operation as in the below image

In real-time, you will get the payload from the UI developer to test/debug the same or from the trace(Tracing: we will cover in due course)

But if you want to create the payload manually then take care of case sensitiveness and get the validation from external formatting tools like https://jsonformatter.curiousconcept.com/#

Now, let’s move to the coding part: The basic requirement is to create a sales order in reference to sales order provided in the payload. In the current example lets create a sales order with reference to sales order 98

Code implemented inside the create_entity method after redefining the method.

Note: This is sample logic, you can implement any logic as per your need once received the payload

  ENDMETHOD.

As a result, a new sales order was created in the system
