scenario: vendor to be accessed by two or more different purchase organisat

my scenario is that every plant has got its own purchasing organisation. There are 10 plants with 10 purchasing org.Now i am trying to create a vendor by FK01 and then extending it with MK01. After that i am trying to create a contract with created vendor and also giving the purchasing org 1( as Purch org 1 was given during the vendor creation with t.code MK01. Now when i am trying to create a purc.contract by giving a different ex: purc org 2 i am unable to maintain it. this is logicalyy right also as vendor is created by purc org level. Is there any other way to solve the problem. As contract should be created with vendor from purc org 2 also. This is my specific requirement.

pl discuss.....
