Proforma based on picked quantity and before PGI in EWM

Dears,

I have a requirement where I need to create a proforma delivery based on picked quantity and before PGI in EWM outbound delivery.

I tried following :

After picking is done in EWM outbound delivery and before PGI I checked if the picked quantity is copied/displayed in VL02N, in order to create a delivery proforma F8 based on delivery, but unfortunally it wasn't.

So I thought maybe there is a way I can generate a proforma from EWM right after picking.

What do you think?

Thanks for your feefback
