Problem in Material Text in STO

Dear All,

I have made a STO Purchase Order. As soon as I enter a Material Code, system will show the Standard Material Text maintained in Material Master. Now there are some cases in which I need to change the Standard Material Text.

Now when I do PO Replenishment Delivery through VL10B Transaction, then in Delivery, system is picking the Standard Material Text instead of Changed MATERIAL TEXT in Purchase Order.

So please tell how to resolve this problem.

Kind Regards,

Vishal
