Outstanding payments in case Inventory Org is closed

Hello All,

  I need to help me understand the functionality of  how er can resolve the issue of outstanding paymments in case we close the Inventory org.

 Just to give a background. We are on 11i and we have 

  INV1  in LE1 : Inv Org1 in Legal Entity 1 and in seperate company C1

 INV2 in LE2 : Inv Org2 in Legal Entity 2 and in seperate company C2

Now we want to close INV2  as Company C1 has bought Company C2.

Hence  we will be creating a new Inv Org calle Inv3 in LE1 and bringing in all the inv. information  from INV2 to INV3.Then we would be closing INV2.
