Create IR from SO

Hello All,

There are two organizations V1 and M1.   an Internal requisition is created from V1 for certain item, that IR se imported to OM as an Internal Sales order.  but On hand qty is not available within V1 to fulfill the requirement of IR. but the required quantity is availble in my other store (Inventory Org) M1 and I want to perform inter-org transfer from M1 to V1. but I want to create that Internal Requisition based on the ISO created earlier.

I need to create Internal requisition from sales order to perform interorg transfers from that requisition.
