Purchase Kanban Due Date always the date of the request - no lead time consideration

Hello All,

When the system creates a purchase kanban request (on hand below minimum) which in turn creates a po release, the release always has a due date of the day that the request was created. Our issue is that our purchase parts have lead times which would make the due date, today + X number of days (the lead time). Since it does not factor in the lead time, it would appear that our suppliers are always late to deliver. Is anyone else using purchase kanban and getting around this issue?

Respectfully,

Utah
