RSS P43E060 Requisition Expediter Despatch function issue

Hi

So I entered a requisition that contains lines for 2 different suppliers

                    Line 1: Laptop for Supplier A

                    Line 2: Desktop for Supplier A

                    Line 3: Keyboard for Supplier B

When the requisition has been approved, I then generate the Purchase order through the Requisition Expediter screen. It generated 2 different PO's for 2 different Suppliers

                    PO 1: For supplier A with Line 1 and 2 from Above

                    PO 2: For supplier B with Line 3 from above

After the POs were generated, it redirects to the despatch screen:

I then select both and click the despatch button. Both of the Purchase Order rolled status to the Status Purchase Order Printed. However, the R43500 was only ran once for one Purchase Order.
