Getting text ID and Text object associated with item texts in PO...

Hi,

To print standard text on smartform for a given item in purchase order, I need to find the text ID and object associated with it.

There are various texts like item text, Info record PO text, Material PO Text, Delievry Text, etc...

Now when I go to ME22N, and select item detail for any item -> Texts , how do I get text ID, and object associated with it ?
