Payment term in PO to be picked from Payt trans a/c of Vendor Master

Hi ,

In standard scenario Payment Term in Purchase Order is automatically picked up from Purchasing data of Vendor Master.

Our requirement is Payment Term in Purchase Order should get picked up from Payment Transaction view of vendor master rather than from Purchasing data of Vendor Master.

Is there any user exit or customization to achieve this.

Please help.

Regds,

Ritesh
