Automatic sales order creation??

hi guys,

I need your help!!

We are doing Intercompany stock transfer between our warehouses.we will create Intercompany purchase order between company 1(SUPPLYING PLANT) and company 2(RECEIVING PLANT).

With reference to this Intercompany PO, GRN will take place at the receiving plant.

After GRN,I could see the stocks are now in QTY AVAILABLE at the receiving plant.Then they will create Sales order and release it to the customer.

My question is, I just want to automatically create the sales order, when the stock reaches the receiving plant.

Is it possible???
