PO to be printed with Present Date instead of PO default Date

Hi SAP Gurus,

We have a requirement to Print POs and send the PO to vendor.. as normal process PO would be created on any previous date.. but the PO approval and release would also happen with due time...

But our client requires the time we send the PO to vendor.. it should contain the latest date ie.. the present today's date at the PO header,

I too think this is very logical requirement... but in SAP how to write a program to fetch the present date and place the same in PO header..while any one prints the PO..

i need a simple work around so that the PO is printed with current date with least no of steps..

Thanks in Advance..
