Vendor Email Address to be populated in the Communication Method of the PO
We have a requirement where the vendor email address needs to get populated in the Cover Text of the Communication Method.
When the user changes the PO for eg 4500002984, the vendor mail address needs to get populated in the Cover Page Text of the Communication Method before Save of the Purchase Order.
This needs to happen after the output type is configured and the mail address needs to appear in the Cover Page Text of the Communication Method before the PO save .
Is there any exit or badi to do the same before the Purchase order is saved ?
Thanks in advance,
