EWM RF – Implement custom code in standard RF transaction

Dear Experts,

My cognition of ABAP, and peculiarly the EWM RF Framework, is somewhat limited, truthful I thought I’d crook to the assemblage for assistance .

We are utilizing the modular EWM RF functions (slightly enhanced with Screen Personas). During the picking process, we request to telephone a relation module erstwhile the surface is loaded and aft confirming a position.

In mean transactions, there’s usually the anticipation to integrate customized logic via a BAdI successful the PBO (before the surface is displayed) oregon PAI (after input is processed). I’m wondering however this tin beryllium done correctly successful the RF Framework.

I tin spot the relation modules for PBO and PAI successful the code, but however tin I instrumentality customized logic here? Do I request to wholly regenerate the relation module, oregon is determination a much elegant mode to execute this?

Below are immoderate screenshots of my situation:
