Getting lead selection in SRM PO CHANGE BADI

Hello all gurus,

in SAP SRM 7 is possible to cut & paste item position. The procedure is quite simple: the user can select an item (1), click on "Cut", then select another line (2) and press "Paste".

This operation triggers the CHANGE badi for PO in which a single item is passed, which is the one that was "cutted".

My task is now to get the line (2) in the change badi, in order to know where the line (1) will be copied.

I can easily get all the items of the order via a getdetail () call; I obtain the item situation before the copy.

How can I retrieve information about the lead selection currently active ?

Waiting for your help, best regards

M.
