Hi Suresh,
What you can do is, show a message when you save the second purchase order.
This is what SAP does for system objects.
For example:
I open two PO screens (in add mode). Both show Document number as 5.
Then I save the forst PO. When I save the second PO, SAP shows a message telling actaul document number saved was 6.
Thanks
