SAP Note 24222 - Positive lead-time in BOM for lead time scheduling

Symptom:

A positive lead-time is not taken into consideration for lead time scheduling of planned orders (e.g. during requirements planning).

Other terms

Negative lead time, scheduling, positive lead time, planned order,
NLFZT

Reason and Prerequisites

The entry of a positive lead time in the MRP data of a BOM component makes no sense for lead time scheduling.

Solution
The positive lead time is the number of workdays in which a component must be available after the start date of the higher-level assembly.
The entry of a positive lead time in the bill of material should show the time interval between the starting date of the order and the starting date of the operation to which the component is allocated, for the case in which no lead time scheduling is carried out.
If lead time scheduling is, however, calculated with the help of a routing, the requirements date of material components is derived from the operation date. For this reason, an entered positive lead time is not taken into consideration for lead time scheduling.
