So far in the course you created demand for a number of MRP parts through sales orders, sales forecast, and master production schedule entries. The next step is to run the MRP process. In this workshop, run the MRP process (Regenerative).
Navigate to Process MRP.
Menu Path: Production Management > Material Requirements Planning > General O perations > Process MRP 1. Navigate to the Filter sheet.
2. Click the Site button and search for and select Main Site. 3. Navigate to the Selection sheet.
4. In the Processing Options section, select Regenerative.
In the Last Run section, the Date, Time and User ID fields default from the Epicor application information. Select the Net Change option to ignore any previously processed Material Requirements Planning (MRP) information. This option changes unfirm jobs and purchase order (PO) suggestions only as demand changes in orders, forecasts, or master production schedules (MPS).
Selecting the Regenerative option processes all outstanding sales orders, forecasts and MPS entries, as well as jobs or POs previously created by MRP. Previous unfirm jobs and PO suggestions are deleted. New unfirm jobs and suggested POs are then generated.
5. Enter the following information:

Defines that the Process MRP does not observe material constraints during its scheduling calculations. When a material is constrained, Clear

the scheduling functionality determines when a material is available for an operation and then uses this date as the operation's Start Date. This allows operations and purchasing start dates to be placed in the schedule before the Schedule Start Date. This option overrides the Select

Defines that the day number value is to be used during the Process MRP. This value, defined on a part record, indicates how many days Select

6. Click Process. 7. Exit Process MRP.
8. From the Main Menu, navigate to System Setup > System Maintenance > System Monitor to verify the MRP process is complete.
9. Navigate to the Active Tasks > List sheet.
The MRP process displays within the Active Tasks grid. The MRP process can take a few minutes to complete; periodically click the Refresh button. When the MRP process has finished, it no longer displays within this grid.
