Automatic release of Purchase Order against the BPA at regular frequency

Summary: Automatic release of Purchase Order against the BPA at regular frequency

Content (required): We are trying to see if we can have an automated way of creating purchase orders(with or without backing requisition) as a release against the BPA at regular interval without any manual intervention.

The requirement is to have a specific set of items(on BPA) to be delivered to specific location at regular interval(say once in a month). Since we don't have planned purchase orders, how can we achieve this?

We tried to utilize the Opt in Establish Order Generation Scheduled by Supplier Agreement.
