Computer-Assisted Master Scheduling
By defining time fences for master scheduled items, you can let MRP
control orders outside of a specified time period and allow the master
scheduler to control orders within that time period. To use this approach
to master scheduling, in the Time Fence field in Item Master Maintenance
(1.4.1) or Item Planning Maintenance (1.4.7), specify a planning horizon,
in calendar days, for each master scheduled item. When MRP plans
orders for these items, it will not schedule order due dates within this time
fence.
Note The time fence for an item should generally be equal to the
cumulative lead time for that item.
To use the computer-assisted approach for master scheduling, set the
following values for each master scheduled item in Item Master
Maintenance (1.4.1) or Item Planning Maintenance (1.4.7).
Master Schedule. Yes.
Plan Orders. No.
Order Policy. Any option other than blank.
Time Fence. The cumulative item lead time.
Selective Materials Plan
Selective Materials Plan (23.3) lets you plan master scheduled items
separately from MRP items. If you use the computer-assisted approach to
master scheduling, you may want to run Selective Materials Plan as
follows.
1 Run Selective Materials Plan for master schedule items only.
2 Adjust the master schedule and rerun Selective Materials Plan as
needed.
3 Run Selective Materials Plan for MRP-scheduled items only.
