EXIT PO Item to get COBL-KOSL

Hi friends.

I've already added three fields in PO Item with EXIT/append CI_EKPODB.

I need to take part of COBL-KOSTL (511 screen) in fields A and B (ZZ fields) during EXIT processing from field COBL-KOSTL. Because these EXIT's doen't see this value which is out of its scope.

I tryied creating a enhancement point in screen 511, and I can EXPORT this value to MEMORY. But it works only in ME22. I need it independent in which tramnsaction I use, ME22 or ME22N. In ME22N it doesn't work because I couldn't create any enhancement point (implicit). It's OO and doesn't let me to do the right thing.

I tryied to encode BADI ME_GUI_PO_CUST in some methods but it doens't stop on my test's BREAKPOINT.

Any idea ?

thanks,

Glauco
