Auto PR/PO creation during sales Order save

Hi SD experts,

I have a requirement to create Auto PR/PO in a different plant upon saving the sale Orders.

Sales Order will be entered in plant 1000 (Sales) but PO should be created in plant 2000(Receiving) with reference to the Sales Order Items.

Please let us know if that is possible.

I already checked item category to Automatic PO and Sch, line category to create PR But the system is creating PR in the sales plant but I need to override this to create it in a receiving plant which is 2000.

Thanks!
