How to Make a Copy of Datasource 0CO_OM_OPA_6 in ECC?

Hi there,

I am facing a scenario where I need to create a new datasource that is the same as 0CO_OM_OPA_6 in ECC. Looking at the datasource, it mentions that it extracts the data using function module BWOMD_GET_ORDCSTA1. However when I try to use that function module, it requires an extract structure.

When I look at the datasource to see which extract structure the business content one uses, the field is blank as is the function module field.

My question is: Is it possible to use the same function module as the business content, or will I have to create my own? If it is possible, where can I find the extract structure that the business content uses?

Thanks in advance for any help provided.
