PP_Reservation quantity

Dear Friends,

I have released my production order. So based on my BOM the system creates reservation for my order. Let us assume my reservation quantity as 100 each.

While i am confirming my ordeer in CO11, in the goods movement, the user wants to enter 110 each ( 10 pieces more than reserved quantity). I am having enough stock in my store. But this particular item getting failed while confirming the order.

If i go to transaction COGI, i am getting INFORMATION (not error) as

" Reserved quantity is exceeded by 10 each"

HOW TO MOVE THIS QUANTITY 110 for that order?

Thanks

Senthil
