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
- Machine workload per work center resource, load type, operation and
workday is calculated for the selected sources. The result in its most
detailed form can be displayed in the Machine Load Details
window.
- If the Include CRP for Labor is selected, the labor workload per
labor class, load type, operation and workday is calculated for the selected
sources. The result in its most detailed form can be displayed in the
Labor Load Details window.

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:
- 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.
- Select the Stop CRP On Error check box, if you want to stop the CRP process when an error occurs.
- Select the Include MS Proposed Receipts check box, if you need to include MS created receipts to the current CRP calculation.
- Select the Include MRP Requisitions check box, if you need to include MRP requisitions to the current CRP calculation.
- Select the Include PMRP Requisitions check box, if you need to include PMRP requisitions to the current CRP calculation.
- Select the Include CRP for Labor check box, if you want to calculate the labor load for the selected site.
- Select the Recalculate Machine Capacity for Site check box, if you want to calculate the
work center resource capacity for the selected site.
- Select the Recalculate Labor Capacity for Site check box, if you want to calculate the
employee capacity for the selected site.
- Enter the date which you need to calculate the machine and labor capacity data in the
Calculation to Date field.
- 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.
