Perform Project MRP

Explanation

This activity is used to perform project material requirements planning with a single project (project MRP) or with multiple projects (multiproject MRP). The application creates project MRP planned orders and offers suggestions for planning orders for optimal manufacturing, considering material availability.

Part requirements can be ascertained based on the sources of supply and demand such as shop orders or customer orders. If project MRP was performed previously, then all the planned supplies and action messages generated in the previous process will be removed first. The results of project MRP suggest a process for fulfilling the demands using, for example, purchase or shop order requisitions. These results also suggest how to plan orders for optimal manufacturing in view of material availability. Project MRP plans the supply for all the parts with a dependent demand. The product or recipe structures of the parts must have been entered. After the structures are entered, you can run project MRP for all the parts with a dependent demand. Project MRP considers only company-owned stock and activity specific requirements. Planning methods B, C, N, O, and T are excluded by project MRP.

Prerequisites

• Project MRP identifies supply and demand for project MRP parts generated in the following IFS modules: IFS/Customer Order, IFS/Purchasing, IFS/Project Master Scheduling, IFS/Shop Order and IFS/Work Order only if those demands are tagged with PPSA.
• To perform multiproject MRP, a planned netting group must have been defined in IFS/Project.

Project MRP requires the following general prerequisites:

• Bill of Materials (BOM) must have been defined for the parts, and lead times for both purchased and manufactured parts must have been established. The product structures must be in the Plannable or Buildable status, otherwise the BOM explosion will stop. Project MRP only uses the existing product structure with the alternate indicated by an asterisk (*).
• Project MRP calculation will consider inventory parts that have the MRP Control flag check box selected on the Inventory Part/Manufacturing tab.
• Before you can run project MRP, you must go through an extensive set up in the IFS/Inventory and IFS/Purchasing modules in IFS Distribution. You must create calendars and attach them to the sites. You must have entered basic data in IFS Manufacturing and the IFS/Shop Order. Since project MRP is based on the quantity on hand and planned orders, data must be available in these components.
• In addition to the basic requirements for project MRP as discussed above, customer orders, shop orders, and purchase orders for these parts need to exist. There is much additional information that affects project MRP, and it is important that you verify this information and its accuracy before running any calculations.
• Inventory parts with the DOP supply code are managed within DOP.
• Project MRP calculation will consider inventory parts with a part that allows demand and supply.
• PPSA must be in the Released status.

System Effects

• A new background job for the project MRP process will be started, and it can be queried for in the Background Jobs window.
• After the process is executed, it can get the Error, Warning, or Ready status.

• The project MRP will generate shop order requisitions for the parts that must be manufactured and purchase requisitions for parts that must be purchased. Shop order requisition type and purchase requisition IDs are projectt MRP. Shop order  requisitions that are not converted to shop orders will be deleted in the next project MRP process.
• The project MRP will calculate the lowest level code parts and update the Low Level field on the Inventory Part/Manufacturing tab.
• In the multiproject MRP process, when a user specifies a planned netting group (PNG), the system creates a project MRP planned material transfer requisition (MTR). The multiproject MRP process creates material transfer requisitions in addition to shop requisitions and purchase requisitions. MTRs created by the multiproject MRP will not have the MTR Manually Created check box selected.
• When creating MTR, the Generate MTR for Planning Only check box in the Planned Netting Group window determines the type of MTR that will be created by project MRP. If the check box selected, project MRP will create MTR with the Planning type. If it is not selected, possible MTR types that will be created are: Transfer, Borrow and Payback.
• If the Generate Safety Stock check box is selected in Project Navigator/Activity List, Project Navigator/Activity, Activity/General or Activities window, and if the part has safety stock specified in the Inventory Part/Planning Data tab, then safety stock will be generated for this part and activity when running project MRP.

Procedure

1. Open the Perform Project MRP per Activity, Perform Project MRP per Project PNG or Perform Project MRP per PNG dialog box depending on the way you want to perform project MRP.
2. Your default site appears in the Site field. Enter the site for which you want to run project MRP. Use the List of Values to select from the available sites. Entering a value in this field is required.
3. In the Project ID field, enter the ID of the project for which you want to run project MRP. (If you enter the wild card (%) or leave the field blank, project MRP is run for all open projects under the specified site).
4. In the Planned Netting Group field, enter the ID of the PNG for which you want to run project MRP. (If you enter the wild card (%), the system will process all PNGs belonging to the specified site).
5. In the Run Date field, enter the date on which you want to run project MRP. The current date is used by default.
6. If you want to stop the project MRP process if an error occurs, select the Stop PMRP on Error check box.
7. If you want to add a day's lead-time back off to the planned receipts, select the Add 1 day Lead Time check box.
8. If you want to create messages for phantom part dependent demands, select the Phantom Part Dependent Demand check box.
9. If you want the project MRP process to create safety stock replenishment orders on the project MRP run date, select the Plan Safety Stock Receipt on PMRP run Date check box. If it is not selected, safety stock replenishment orders will be created on the event date itself.
10. If you want to exclude PPSAs defined in any PNG when performing project MRP (not multiproject MRP) and when using the Perform Project MRP per Activity dialog box, you have the option of selecting the Exclude PPSAs grouped under any PNG check box.
11. If you want to start MRP after project MRP is completed, select the Start MRP Process once PMRP is completed check box.
12. If you want MRP to include alternate components in the planning calculation, select the Plan Alternate Component check box. This will be enabled only after selecting the Start MRP process once PMRP is completed check box.
13. Click OK.
