PO order exceeded error while GR

Hello Gurus,

I created a PO for 100 units with the tolerence for underlimit and overlimit as 10%. Now wen I want to post GR for 107 units units its gives the error "PO order exceeded by 7 units".

Does the overlimit of 10% doesn't mean that i can post upto 110 units into GR.

Plz suggest me wats the problem?? Also suggest any changes to make to post 107 units

Thanks
