why automtically master Org assign for all those Location not tied with Organization.

Dear Gurus,

As we aware the importance of Deliver to Location in iProcurement which is acutally tends to defines the default the ship to organization as selected Deliver to Location tied to what organization.

We have many locations and to assign all of them to an specific organization is not recommended because it varies sometime based on the requirement, we have observed that in iProcurment all those location which are not tied with any organization are showing as linked with MASTER ORG in Deliver to Location LOV.

I mean why ?? because of this we are facing a lot of pain in receving and there are thousands of transactions we do have on daily basis ??
