Global Blanket Agreement

 Hi,

In our organisation,we have created four Inventory organisations in one OU.Our requirement is that we want one Global agreement with a supplier who will supply the goods to all the inventory organisations.

I have been told that we will have to create seperate blanket agreements for each Inventory organisation. Is there a way by which i create only one blnaket agreement which is applicable to all the inventory organisations within an OU.

Thanks...
