Determination of lead time

	Determination of lead time When LN determines the default planned delivery date in the Warehousing Orders (whinh2100m000) session, LN also takes into account the lead time. The lead time is determined as follows: If the Ship-from Code is a business partner and the item is specified, LN retrieves the business partner's internal lead time from the Supply Time field and the lead time unit from the Unit for Supply Time field of the Items - Purchase (tdipu0101m000) session. In all other cases, LN retrieves default lead times from the Item Data by Warehouse (whwmd2510m000) session, and lead times for items-by-warehouse from the Warehouses (whwmd2500m000) session.
