This chapter contains these topics:
After you generate the material requirements plan, you must validate it to ensure that you have sufficient work center capacity. Use Capacity Requirements Planning (CRP) to determine whether the material plan can be executed with the resources that are available.
You also use CRP to:
Analyze all active work centers
Identify the pacing resource for work centers, which is either labor or machine, depending on which one would increase the work centers' capacity
Calculate the rated capacity for work centers
Calculate the MRP load for work centers
In the JD Edwards World software, the same batch program generates capacity planning information for both CRP and Rough Cut Capacity Planning (RCCP). You can vary the settings in the processing options to accommodate the different requirements for CRP.
The primary differences between CRP and RCCP are:
CRP analyzes all active work centers instead of only the critical work centers.
CRP offers more alternatives to level an overloaded time frame.
The system uses the following inputs to CRP:
Firm MRP work orders and routing instructions
Planned MRP work orders and routings
Service parts' forecast
Service parts' sales orders
Inter-plant demands
The system generates the following outputs from CRP:
Over-capacity and under-capacity messages
Work center load
Work center load graph
Period summary
Validating the material requirements plan consists of the following tasks:
Generating Capacity Requirements Plans
Reviewing Capacity Requirements Plans
The programs that you use to validate the material planning schedule are the same programs that you use to validate the master schedule for DRP, MPS, and RCCP.
See Also:
Section 20.1, "Validating Master Schedules" for detailed information on these programs.
From Resource & Capacity Planning (G33), choose Periodic Capacity Requirement
From Periodic Resource/Capacity Planning (G3321), choose Capacity Requirements Plan
Use the Capacity Requirements Plan program to compare prospective MRP resource requirements to the capacity available in work centers. CRP indicates if you should revise the material requirements plan to create feasible work loads or improve use of limited resources.
Report hours and quantities for operations that are complete or partially complete to ensure that the figures for Released Load are correct. See Work with Hours and Quantities in the JD Edwards World Shop Floor Control - Discrete Guide.
Verify that resource units exist for all work centers in your generation. See Setting Up Resource Units in the JD Edwards World Shop Floor Control - Discrete Guide.
Set up supply and demand inclusion rules. See Section 21.2, "Setting Up Supply and Demand Inclusion Rules" for MRP.
Run MRP generation. See Chapter 36, "Generate Material Requirements Plans."
See Also:
Section 20.2, "Generating Rough Cut Capacity Plans" for information on the processing options.
When you generate a capacity requirements plan, the system creates a time series that shows the load during each planning period for a work center. You can view the time series as a spreadsheet or as a graphical display. If you have organized several work centers as a dispatch group according to common functions, similar operations, or steps in routing, you can view the group to see how capacity affects all of the work centers in the group.
You can review summaries of each period to determine the load that is placed on a work center by each item or order. You can also review messages for each work center and delete, clear, or hold messages. If the system encounters over- or under-capacity conditions, you can review the plan and identify the periods or work centers in which the conditions occur. It might be necessary to adjust the forecast or capacity and generate CRP again.
Reviewing the capacity requirements plan includes the same programs used to review the resource requirements plan.
Complete the following tasks:
Review dispatch groups for capacity requirements planning
Review work center load for capacity requirements planning
Review period summaries for capacity requirements planning
Review MRP work schedules on the dispatch list
Review MRP rate schedule and work order loads
Validate capacity requirements plan
From Resource & Capacity Planning (G33), choose Daily Capacity Requirements
From Daily Capacity Requirements Planning (G3313), choose Review Dispatch Group
If you have several work centers that are organized as a dispatch group, you can view the group to determine how capacity affects all of the work centers in the group. Dispatch groups enable you to organize work centers according to common functions, similar operations, or routing steps.
When you review dispatch groups, you can also review messages about all the work centers in the group and use that information to redistribute the load within the group.
When you review dispatch groups for CRP you use the same program as when you review dispatch groups for Resource Requirements Planning. You can vary the settings in the processing options to accommodate the different requirements for CRP.
See Also:
Section 12.2, "Reviewing Dispatch Groups for Resource Requirements Planning" for information on the processing options.
From Resource & Capacity Planning (G33), choose Daily Capacity Requirements
From Daily Capacity Requirements Planning (G3313), choose Review Work Center Load
You can review the capacity load at each work center. Use this information to determine whether to adjust capacity or the forecast. You can view the time series as a spreadsheet or as a graphical display. The spreadsheet provides a numerical breakdown, by planning period, of the load placed on a work center.
The bar graph provides the same information as Review Work Center Load. The graph uses time series information from Resource Requirements Load to generate the comparison. The system displays the capacity load at the work center for each planning period based on several calculations.
Review Work Center Load for CRP uses the same program as Review Work Center Load for Resource Requirements Planning. You can vary the settings in the processing options to accommodate the different requirements for CRP.
Verify that your resource units and capacity requirements plan are current.
See Also:
Section 12.3, "Reviewing Work Center Load for Resource Requirements Planning" for information on the processing options.
From Resource & Capacity Planning (G33), choose Periodic Capacity Requirements
From Periodic Resource and Capacity Planning (G3321), choose Period Summary report
In addition to reviewing the capacity load of a work center, you can also evaluate the load placed on a work center by item. You can review period summaries either online or through a printed report. You can review:
The items that are scheduled for a work center
The number of units of an item that make up the load
The percent of the total load on the work center that is for a specific item's forecast
You use this information to determine whether to adjust the forecast or the capacity at the work center.
When you review period summaries for CRP you use the same program as when you review period summaries for Resource Requirements Planning. You can vary the settings in the processing options to accommodate the different requirements for CRP.
To evaluate the load placed on a work center by item, you can review the Period Summary Report.

From Resource & Capacity Planning (G33), choose Daily Capacity Requirements
From Daily Capacity Requirements Planning (G3313), choose Dispatch List
Use the Dispatch List to locate and update work center scheduling information. This workbench environment serves as a starting point for work center scheduling and the release of work to the floor. Use this program to:
Access work order information, such as the header and parts list
Display work order information, such as work center, remaining labor, machine hours, and setup hours
Sort work orders by start date, requested date, or status code operation
Change the work order status code, start date, or requested date
The Dispatch List for MRP uses the same program as the Dispatch List for DRP/MPS. You can vary the settings in the processing options to accommodate the different requirements for MRP.
See Also :
Section 38.3.4, "Reviewing MRP Work Schedules on the Dispatch List" for the processing options for this program.
From Resource & Capacity Planning (G33), choose Daily Capacity Requirements
From Daily Capacity Requirements Planning (G3313), choose Schedule Review
Use Schedule Review to review the rate schedule load and the work order load for a work center for a day, week, or month. You can also select a specific date range to view the load for the work center. If you need to adjust the scheduled load at the work center, you can access several different forms to make adjustments.
Schedule Review is used primarily for rate based items and is an alternative for viewing load on a work center. A processing option allows you to include work order generated loads before or after rate loads.
When you review schedules for MRP you use the same program as when you review schedules for DRP and MPS. You can vary the settings in the processing options to accommodate the different requirements for MRP.
See Also:
Section 20.4, "Reviewing Rate Schedule and Work Center Loads" for the processing options for this program.
Validating the capacity requirements plan consists of identifying the overloaded work centers, making adjustments in forecast or resources, and generating the plan again to see if the adjustments you have made have evenly distributed the loads on the work centers.
To validate a capacity requirements plan
Complete the steps for reviewing the requirements plan.
Revise the forecast.
See Revising a Summary of Forecast in the JD Edwards World Forecasting Guide.
Complete the steps for generating the requirements plan.
Complete the steps for reviewing the revised requirements plan.
Repeat the steps until all loads at each work center are appropriate.
