I have set up the trading partner setup and mandatory setups required for Xml gateway Outbound Process.
I created a PO for the Supplier who was defined as a trading partner.On Approval i got the xml payload as email for the mail id which was specified in the Trading Partner Definition.
But when viewed at the subject , i get PO-<Po Number>-<Revision Number>-<Organization>
Now i wanted to add some static message at the beginning .
<Some Static Message>PO-<Po Number>-<Revision Number>-<Organization>
So that when i receive the xml payload in mail , my subject should be shown as shown above.
