releasing buy item from MRP

Hi,

When releasing a planned order from MRP for a buy item, is it possible to go automatically up to the creation of a STANDARD purchase order ?

That's possible in min/max replenishment but I do not see a way in MRP, only creation of releases of blanket agreements with an ASL.

Min/max creates an incomplete requisition and approves it, launching at the end the PO creation workflow.

MRP creates an approved requisition and then launches the create releases request that does not handle standard PO.

Please correct me if I'm wrong.

Thanks,
