How can I automatically calculate blanket purchase order requested delivery dates?

Opt in to the Automatically Determine Requested Delivery Date Using Agreed Lead Time feature to enable requested delivery date calculation. In the blanket agreement, set the Lead Time Days line attribute.

When requisitions are converted to orders, the requested delivery date on the requisition line is compared to the current date plus the Lead Time Days on the agreement line. The later date is used for the requested delivery date on the order.
