EWM RF – Implement custom code in standard RF transaction

[simonweber]

Dear Experts,

My knowledge of ABAP, and particularly the EWM RF Framework, is somewhat limited, so I thought I’d turn to the community for help 😊.

We are using the standard EWM RF functions (slightly enhanced with Screen Personas). During the picking process, we need to call a function module when the screen is loaded and after confirming a position.

In normal transactions, there’s usually the possibility to integrate custom logic via a BAdI in the PBO (before the screen is displayed) or PAI (after input is processed). I’m wondering how this can be done correctly in the RF Framework.

I can see the function modules for PBO and PAI in the code, but how can I implement custom logic here? Do I need to completely replace the function module, or is there a more elegant way to achieve this?

Below are some screenshots of my situation:

EWM RF Picking Screen – when this screen is presented it should trigger a function model and after confirming the task it should trigger again a function model.

Any tips are greatly appreciated.

Best Regards

Simon
