Perform Project MRP

Explanation

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

The supply and demand will be calculated for PMRP parts based on shop orders, customer orders, etc. Planning methods B, C, N, O, and T are excluded by PMRP.

Prerequisites

• PMRP sees supply and demand for PMRP 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 multi project MRP (MPMRP), a planned netting group must have been defined in IFS/Project.

PMRP 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. PMRP only uses the existing product structure with the alternate indicated by an asterisk (*).
• PMRP calculation will consider inventory parts that have the MRP Control flag check box selected on the Inventory Part/Manufacturing tab.
• Before you can run PMRP, 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 PMRP is based on the quantity on hand and planned orders, data must be available in these components.
• In addition to the basic requirements for PMRP as discussed above, customer orders, shop orders, and purchase orders for these parts need to exist. There is much additional information that affects PMRP, 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.
• PMRP 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 PMRP process will be started , and it can be queried for in the Background Jobs window.
• After the process is executed, it can take the Error, Warning, or Ready status.

• The PMRP 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 PMRP. Shop order  requisitions that are not converted to shop orders will be deleted in the next PMRP process.
• The PMRP will calculate the lowest level code parts and update the Low Level field on the Inventory Part/Manufacturing tab.
• In the MPMRP process, when a user specifies a planned netting group (PNG), the system creates a PMRP planned material transfer requisition (MTR). The MPMRP process creates material transfer requisitions in addition to shop requisitions and purchase requisitions. MTRs created by the MPMRP will not have the MTR Manually Created check box selected.

Note: 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 PMRP. If the check box selected, PMRP will create MTR with type Planning. 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 PMRP.

Procedure

This procedure is applicable to the Perform PMRP per Activity, Perform PMRP per Project and Perform PMRP per PNG dialog boxes. Open the dialog box which corresponds to the way you want to perform PMRP.

1. Your default site appears in the Site field. Enter the site for which you want to run PMRP. Use the List of Values to select from the available sites. Entering a value in this field is required.
2. In the Project ID field, enter the ID of the project for which you want to run PMRP. (If you enter the wild card (%) or leave the field blank, PMRP is run for all open projects under the specified site.) If you are using the Perform PMRP per PNG dialog box, you cannot enter any value here. Perform the next step instead.
3. In the Planned Netting Group field, enter the ID of the PNG for which you want to run PMRP. (If you enter the wild card (%), the system will process all PNGs belonging to the specified site.) If you are using the Perform PMRP per Project dialog box, the PNG ID appears automatically, based on the project ID that you entered in the previous step. If you are using the Perform PMRP per Activity dialog box, you cannot enter any value here.
   
   Note: If you leave both the Project ID and Planned Netting Group fields blank, the system will perform the project MRP process for all the projects and all the PNGs belonging to the specified site. You must enter either the project ID or the PNG but not both. To perform MPMRP, you must use the Perform PMRP per PNG dialog box.
    
4. In the Run Date field, enter the date on which you want to run PMRP. The current date is used by default.
5. If you want to stop the PMRP process if an error occurs, select the Stop PMRP on error check box.
6. If you want to add a day's lead-time backoff to the planned receipts, select the Add 1 day leadtime backoff to planned receipts check box.
7. If you do not want to create messages for phantom part dependant demands, select the No message for phantom part dependent demand check box.
8. If you want to start MRP after PMRP is completed, select the Start MRP process once PMRP is complete check box.
9. If you want the PMRP process to create safety stock replenishment orders on the PMRP 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.
   Note: When performing Project MRP (not MPMRP), you have the option to exclude PPSAs defined in any PNG by selecting the Exclude PPSAs grouped under any PNG check box.
