Knowledge: Buy Order Lead Time Compressed in Constrained Plan with EPLT=Yes

Summary:

This video explains why a constrained plan can compress buy order lead time even when Enforce Purchasing Lead Time is set to Yes. In the demonstrated scenario, the behavior occurs because a downstream firm work order drives the plan to pull in the purchased component dates to support the firm requirement on time. The video walks through the item setup, lead time configuration, downstream supply chain relationship, and the planning logic that causes the compressed buy order dates.
