4.2.4.1. Run MRP by Planner Code

When you run MRP by Planner Code, you are running the Material Requirements Planning (MRP) system. This utility creates Planned Replenishment Orders to meet existing Sales Order and Work Order demand. Replenishment Orders will be created whenever a Planned Availability for an Item Site falls below its Reorder Level. The quantity of the Replenishment Order will be enough to restore Planned Availability back to the Reorder Level—or to the Order Up To (OUT) Level, if the OUT Level is greater.

Note

Running MRP by Planner Code may be used to generate Planned Orders for both parent-level manufactured Items and also lower level purchased Items. Only Items designated as MRP Items will be affected by an MRP run.

To run MRP by Planner Code, select the "Run MRP by Planner Code" option. The following screen will appear:

Run MRP by Planner Code

Note

The system deletes any non-firmed Planned Orders when MRP is run. If demand for the deleted Planned Orders still exists, the Orders will be replaced by new Replenishment Orders having new Planned Order Numbers. Order quantities will also be updated if demand levels have changed since MRP was last run.

When running MRP by Planner Code, you are presented with the following options:

All Planner Codes: Select to create Planned Replenishment Orders for all Planner Codes.
Selected: Specify Planner Code you want to create Planned Replenishment Orders for.
Pattern: Enter a Planner Code pattern to select a range of Planner Codes. Refine your search using Regular Expressions, as described in Section 1.2.9, “Topic: Pattern Matching with Regular Expressions”.
All Warehouses: Select to create Planned Replenishment Orders by Planner Code for all Warehouses.
Selected: Specify Warehouse Planned Replenishment Orders should be created for.
Cutoff Date: Specify how far into the future the MRP run should look for demand.

Tip

If you schedule an MRP or MPS job submitted to the Batch Manager to run on a periodic basis—daily, weekly, monthly—the cutoff date used for the run will automatically be updated by the number of days in the specified reschedule interval (Day = +1, Week = +7, and Month = +30).

Delete Existing Firmed MRP Orders: Firmed MRP Orders: Select to delete existing Firmed Orders. A firm Planned Order is a Planned Order that has been solidified in the schedule. By default, firm Planned Orders are not deleted when MRP is run. Selecting this option overrides that default behavior. If firm Planned Orders are deleted when MRP is run, they will automatically be replaced by soft (i.e., non-firmed) Planned Orders, assuming the demand for the requirements still exists.

Tip

Unposted Purchase Orders and Purchase Requests are considered as valid sources of supply when MRP is run.

To the far right of the screen, the following buttons are available:

CANCEL: Closes the screen without creating Planned Replenishment Orders by Planner Code, returning you to the application desktop.
CREATE: Creates Planned Replenishment Orders by Planner Code, using the specified parameters.
SUBMIT: Select to submit the MRP run to the Batch Manager. For additional information, see Section 10.5, “Topic: Submitting Reports and Jobs to the Batch Manager”.

4.2.4.2. Run MRP by Item

When you run MRP by Item, you are running the Material Requirements Planning (MRP) system. This utility creates Planned Replenishment Orders to meet existing Sales Order and Work Order demand. Replenishment Orders will be created whenever a Planned Availability for an Item Site falls below its Reorder Level. The quantity of the Replenishment Order will be enough to restore Planned Availability back to the Reorder Level—or to the Order Up To (OUT) Level, if the OUT Level is greater.

Tip

When running MRP by Item for manufactured Items, the system generates Planned Work Orders only. If you want to also generate Planned Orders for purchased requirements, you should run MRP by Planner Code. Only Items designated as MRP Items will be affected by an MRP run.

To run MRP for an individual Item, select the "Run MRP by Item" option. The following screen will appear:

Run MRP by Item

Note

When running MRP by Item, you are presented with the following options:

Item Number: Enter the Item Number of the Item you want to create a Planned Order for.
UOM: Inventory Unit of Measure.
Warehouse: Specify Warehouse Planned Replenishment Orders should be created for.
Cutoff Date: Specify how far into the future the MPS run should look for demand.
Delete Existing Firmed MRP Orders: Firmed MRP Orders: Select to delete existing Firmed Orders. A firm Planned Order is a Planned Order that has been solidified in the schedule. By default, firm Planned Orders are not deleted when MRP is run. Selecting this option overrides that default behavior. If firm Planned Orders are deleted when MRP is run, they will automatically be replaced by soft (i.e., non-firmed) Planned Orders, assuming the demand for the requirements still exists.

Tip

Unposted Purchase Orders and Purchase Requests are considered as valid sources of supply when MRP is run.
