I 'm just checking if there is any BADI to check item fields and in case set these fields in grey or better said as not changeable.
At the moment I have found Badi which perform at the moment of saving docs, and unfortunately this is not sufficient for my purposes.
I 'd like to find one which perform once the sales doc is opened and user try to modify item-fields.
In any case this Badi should act before saving sales doc.
Hope it's possible.
Many thanks in advance,
