i have a requirement to use a badi for MM02 txn.
Actually my requirement is that any material having atinn value "0000000076"
should not be used to create sales order if the value associated with its atwrt = 'h'.
(there are two atwrt values for atinn76, which are 'h' and 'f').
Now for this i am using BADI....
Please tell me which badi will be useful for that, and if there is any other
good approach, then also, please tell me.
