PM script for pick list

Hi all,

I need to change the standard Pick list script in PM module.

Can any one shed some light on this?

I know how to change form names to zform and work on it,but in PM I heard I have to go OID1? so do I need to create new record in OID1?

Pls let me know id that the way to work in PM?

Will appreciate ur help

Thanks
