SDRQCR21 and delivery from intercompany Purchase orders

I used the program SDRQCR21 to clean a bad requirement generated by intercompany delivery between to company born by a purchase order (to be clear: the company 1 made a PO to company 2 which create a delivery using the VL10B with this PO).

The program delete the bad requirement but delete also other good intercompany deliveries present over the material, without regenerating these. Now i must found a sistem to recreate these. Why the program don't take again these deliveries? Because they are link to a PO?

thanks
