function module select-options????

how create function module with select-options in sap abap

[Former Member]

please answer Any one step by step

[matt]

Step 1. Read the documentation on select-options and how their data is structured

Step 2. Define appropriate types either in an interface, or in the data dictionary (if FM is to be RFC)

Step 3. Create a function module (and function group if not using an existing one) frdric.girod

Step 4. Create parameters with the type of the select-options you need as defined in Step 2.

Step 2, courtesy of sandra.rossi , many thanks.

I like this way, we put ideas, and you do the job of answering 🙂

thanks matthew.billingham

I should be in management.

[Sandra_Rossi]

matthew.billingham It's worth an answer, and I think you miss the creation of the type between Step 2 and 3, I would recommend defining the type in an interface (or DDIC if it's a RFC function module).

and we don't know if there is a function group ..

(but Why they still using FM ?!?)

Have a look at the "good example" under

https://help.sap.com/doc/abapdocu_latest_index_htm/latest/en-US/index.htm?file=abenencap_class_inter...

The example uses PARAMETERS, but of course, the same holds for SELECT-OPTIONS.

But why are all the methods static?

[retired_member]

Because it is generally sufficient for dealing wit classical dynpros in local classes of function pools. You can do it with singletons if you like but I don't see a benefit of multiple objects dealing with one program-global dynpro.

I know, we have https://help.sap.com/doc/abapdocu_latest_index_htm/latest/en-US/index.htm?file=abenstatic_class_sing..., but simply encapsulating classical dynpros runs under exceptions for me.
