Perform Capacity Requirements Planning

Explanation

This activity is used to start calculating the expected future workload of machines, labor and production groups. You can perform CRP for one site at a time or for all sites to which you have access.

Prerequisites

• The manufacturing plan from MRP or PMRP must already be complete.
• You must have entered the work centers you want to work with, specified the unit of measure in which their capacity is measured, and specified their actual capacity.
• You must have specified if operation scheduling is done with or without parallel operations.
• You must have entered the labor classes you want to work with. You will need to have at least one employee connected to the labor class on the site and that employee needs to be available for at least one day in the time interval.
• You must make sure the shop calendar is up to date. CRP makes sure that the workload is planned for only those days included in the shop calendar. Only workdays should exist in the shop calendar, so weekends and holidays are not counted in CRP.

System Effects

The result from CRP is presented as the total workload per day and work center. Labor load details can be viewed in the Labor Load Details window and using Manufacturing Visualizer.

Procedure

You can execute CRP either by direct execution (Procedure A) or by scheduling the task to execute as a background job (Procedure B). 

Procedure A:

1. In the Site field, enter the site for which you want to run CRP. Use the List of Values for accessible sites. If you leave the field blank, CRP is run for all the sites to which you have access.
2. Select the Stop CRP On Error check box, if you want to stop the CRP process when an error occurs.
3. Select the Include MS Proposed Receipts check box, if you need to include MS created receipts to the current CRP calculation.
4. Select the Include MRP Requisitions check box, if you need to include MRP requisitions to the current CRP calculation.
5. Select the Include PMRP Requisitions check box, if you need to include PMRP requisitions to the current CRP calculation.
6. Select the Include CRP for Labor check box, if you want to calculate the labor load for the selected site.
7. Select the Recalculate Labor Capacity for Site check box, if you want to calculate the labor capacity for the selected site.
8. Enter the date which you need to calculate the labor capacity data in the Calculation to Date field.
9. Click OK.

Note: You do not need to select the check boxes in steps 3,4 and 5, if you have already run MRP, PMRP or MS with the Run Integrated with CRP check box selected. The CRP calculation would have been already done for those requisitions and it would not be required to do the calculation again.

Procedure B:

Click Schedule to open the Create New Task Schedule window. Set the scheduling parameters as desired and save. Scheduled tasks can be seen in Scheduled Database Tasks window.
