Perform Site MRP

Explanation

This activity is used to calculate the supply and demand for material requirement planning (MRP) parts based on shop orders, customer orders, etc. The system creates MRP-planned orders for fulfilling these demands, such as purchase or shop order requisitions, and offers suggestions to plan orders for optimal manufacturing, considering material availability.

The MRP process generates supply and demand for MRP parts generated in the following IFS modules: IFS/Customer Order, IFS/Customer Schedules, IFS/Supplier Schedules, IFS/MRP (for spare parts), IFS/Project, IFS/Project Delivery, IFS/Master Scheduling, IFS/Purchasing, IFS/Maintenance, IFS/DOP, IFS/Distribution Order, and IFS/Shop Order.

Prerequisites

• BOMs must have been defined for the parts, and lead times for both the purchased and manufactured parts must have been established. MRP only uses the existing product structure with the alternate " * " indicated by an asterisk(*). 
• You must have created a master production schedule using IFS/Master Scheduling or you should run PMRP. 

Note: MRP does not process parts with planning methods B - Order Point Planning, C - Replenishment Level, M - Manufacturing Cell Part or N - Next Level Demand. 

System Effects

• After this process is executed, the Warning or Error status can apply. Error indicates that some critical errors have occurred in the process, and the MRP process has stopped. Warning indicates that a message posted for this process has to be reviewed by the user. This can be done by using the View Detail right mouse button option in the Background Jobs window, which displays the message in the status information table. If the user decides to continue the MRP process, the MRP process will display error messages when the process is completed.
• MRP calculation will consider inventory parts where the MRP Control Flag check box in Inventory Part/Manufacturing tab window is selected. 
• MRP will generate shop order requisitions or non-firm production schedules for parts that must be manufactured, and it will generate purchase requisitions for parts that must be purchased.
• Shop order requisitions that are not converted into shop orders or non-firm production schedules are deleted the next time you start the MRP process. MRP calculates the lowest level code of parts and updates the Low Level field on the Inventory Part/Manufacturing tab.

Procedure

You can execute single-site MRP either by direct execution (Procedure A) or by scheduling the task to execute as a background job (Procedure B). 

Procedure A:

1. Open the Perform Site MRP window.
2. In the Site field, enter the site for which you want to run a single-site MRP. Click List to select from the available sites. If you leave the field blank, the MRP process is run for all the sites to which you have access.
3. Select the date on which you want MRP to be executed. The current date is used by default.
4. If you want to stop the MRP process when an error occurs, you can select the Stop MRP on error check box.
5. You can add 1-day lead-time back-off to planned receipts, by selecting the Add 1-day lead-time backoff to planned receipts check box.
6. If you do not want to create messages for phantom part dependant demands, you can select the Don't create messages for phantom part dependant demand check box.
7. If you want the MRP process to create safety stock replenishment orders on the MRP run date, select the Planned Safety Stock Receipt on MRP run Date check box. If it is not selected, safety stock replenishment orders will be created on the event date itself.
8. If you want to get the default values defined by the administrator in the Database Tasks window, click Default.
9. To run single site MRP, you can click OK.

Procedure B:

Click Schedule to open the New Database Task Schedule window. Set the scheduling parameters as desired and save. Scheduled tasks can be seen in Scheduled Database Tasks window
