How to Offset Dependent Demand Due Dates in Aggregate Time Buckets

For constrained supply plans, you can offset dependent demand due dates when planning in aggregate time buckets. You can enforce a more granular control over lead times for subassemblies and components whose dates need to be offset by user-specified lead times.

Use the following attributes in an items simulation set to offset dependent demands into a previous aggregate time bucket:

Lead Time Offset in Week Buckets: The planning process offsets the lead time by number of days used in this attribute for an item and organization when planning in week buckets.
Lead Time Offset in Period or Month Buckets: The planning process offsets the lead time by number of days used in this attribute for an item and organization when planning in period or month buckets.

By using these attributes, you can ensure that subassemblies and components of manufacturing assemblies with lengthy cumulative manufacturing lead times are manufactured and procured on time in the correct aggregate time bucket.

Define the item attributes in a simulation set to adjust the lead times in aggregate buckets. You can also update these attributes in the Items table in plan output and then simulate the plan to correctly offset the lead time.

When planning in aggregate buckets, the planning process considers the lead times based on specific criteria with respect to the two attributes.

For make planned orders, the planning process uses the maximum of processing lead time and aggregate bucket lead time offset attribute for that item.
For planned transfer supplies, the planning process uses the maximum in transit lead time and aggregate bucket lead time offset item attribute value.
For new buy orders, the planning process uses the maximum of processing lead time in the approved supplier list (or processing lead time at item if ASL isn't defined), and aggregate bucket lead time offset item attribute value.
