SAP Gateway Design: How to Write "Display Functional Modules"?

Question

When developing SAP Gateway projects using the SEGW t-code, I always try to import feature sets from function modules / BAPIs.

Besides being very fast and useful, I am also basically able to map data sources to the CRUD-Q methods of the data provider class. This mapping works very well with many FM / BAPIs provided by SAP.

Unfortunately, I do not know how to write function groups / function modules myself, which are also very "displayed". Usually I get GetEntitySet, but none of the others (create, delete, etc.). I do not know what import / export parameters or what else is required to write well-displayed function modules.

There is also the option to import a function module, you can also try this.

Or you can create your own, check out the sample implementation provided by the gateway for TEA_APPLICATION.
