Understanding Requirements Plan Validation

After you generate the requirements plan, either a master schedule or material requirements plan, you can validate it to ensure that you have sufficient work center capacity. Use the CRP/RCCP Regeneration program (R3382) to generate capacity planning information.

In JD Edwards EnterpriseOne software, the same batch program generates capacity planning information for both RCCP and CRP. The only difference is the work centers that you identify in the data selection.

The primary differences between RCCP and CRP are:

RCCP is generally run for end items on the Maser Production Schedule (MPS) and considers only critical work centers.
CRP is generally run for all manufactured items and considers all work centers.

If critical work centers appear in the routings of component work orders that are generated by Material Requirements Planning (MRP), then the system can also include MRP orders in RCCP because both RCCP and CRP use the same batch program.

The CRP/RCCP Regeneration program generates:

Over-capacity and under-capacity messages.
Work center load.
Period summary.

The pacing resource for critical work centers is either labor or machine, depending on which one would increase the work center's capacity. A work center is paced by labor if adding employees to the work center increases capacity. A work center is paced by machine if adding machines increases capacity. Use the Prime Load field on the Work Center Master Revisions form to define the pacing resource.

These terms are important for understanding master schedules:

Resource Units: The resource units are the units that are associated with a work center for each workday on the Work Day Calendar. The system displays resource units as hours, units, monetary amounts, floor space, and so on. This information is associated with a work center for each workday on the Work Day Calendar. The system uses this information to backschedule work orders in JD Edwards EnterpriseOne Shop Floor Management and to calculate available hours for capacity planning. You can manually enter or revise resource unit information for each work center and for each workday using the Work Center Resource Units program (P3007).
Work Center Hours: Work center hours are recalculated using the Work Center Resource Units Generation program (R3007G). You use this program only for processing data. It does not produce a printed report. However, you can view the results of the most recent refresh operation on the Work Center Resource Units form.
