R12- Staging Inventory has balance with a identical -ve balance in Other Inventory

Hi

We are on R12.1.3 and using Inventory, Purchasing and all Financial modules.  We have Inventory called ' Vehicle' which is one of the product line of the Company. It has been observed that there is a -ve balance in VH inventory and identical +ve balance in Staging Inventory. On doing the analysis we found that some of the OM transactions have not hit Staging Inventory as well as VH inventory.

Following is one case study for such transactions
