Hi all,

I have created Material using that material statuses. at the time of purchase requisition and purchase order it is showing ERROR message..

Its ok fine.

But the problem is, the error message is coming at the time of purchase inforecord(mE11).

my requirement is the error message has to come only at the time of purchase requisition and purchase order not at the time of Purchase info record.

i have checked all screen layouts,but no use.
