Call custom wd into standdard POWL

Hi All,

Please answer if worked on WD POWL

I have requirement to enhance   standard WD component which is using POWL concept.

Requirement: Need to add button  “ BUTTON1” I std .

When button is pressed call one custom screen (WD) with some fields.

I have some idea of webdynpro but how to achieve this in feeder class of POWL concept.

My question is:

1) can I call normal WD in feeder class when button "BUTTON1"  pressed if yes how .

2) Or I need to build WD component using  POWL_UI_COMPONET  like FPM (OIF component) .
