Planned Orders
MRP generates planned orders to satisfy net requirements for items with Plan Orders set to Yes and non-blank order policies specified in the item planning data. MRP generates planned work orders for manufactured items, planned line orders for items manufactured on production lines, and planned purchase orders for purchased items based on the item
Pur/Mfg code.
The scheduled release date for a planned order is the item due date minus the purchasing or manufacturing lead time. For manufactured items, MRP calculates planned order release dates using the manufacturing lead time. For planned purchase orders, both the inspection lead time and the purchasing lead time are used. If a planned order release date falls on a non-workday, MRP schedules it for the last prior workday.
When MRP plans orders, it uses the default shop calendar for the site. If there is no shop calendar, MRP does not plan orders for that site.
Planned purchase, work, and line orders are stored with status Planned. Work orders and line orders are created with work order bills; purchase orders are not. A planned order, regardless of its type, can be approved using any of the planned order approval programs.
If you do not plan to act on a planned order, you should delete it, particularly if MRP will not be run soon. The system assumes you will take action on planned orders. Master schedule inquiries and reports include master scheduled order quantities, which are assumed to be supply and, therefore, included in available to promise. MRP inquiries and reports show all planned orders; these are not seen as supply.
