Perform Planning Network MRP

Explanation

This activity is used to calculate the supply and demand for MRP (Material Requirement Planning) parts (including multi-site planned parts ) based on shop orders, customer orders, etc, for a particular planning network. Parts that are sourced from an internal supply site in the planning network will be a multi-site planned part. (It can be supplied externally as well.) Once the multi-site product structure's sourcing rules are defined, multi-site planning can be performed. The multi-site product structures are defined regardless of the planning networks. The system creates MRP planned orders for fulfilling demands, such as purchase or shop order requisitions. The system also offers suggestions on planning orders for optimal manufacturing considering material availability. MRP generates the distribution orders for the demands on the sites in the planning network. Manufactured and acquired split data in the Inventory Part/Planning tab window will be considered when creating the supplies by MRP. 

Only the sites to which the users has access, can be added or removed from a planning network. A planning manager will enter planning network information into the system. Planners and managers can review this information.

Prerequisites

• The sites for the network must have been defined
• The user allowed sites must have been defined.
• Multi-site planned parts must have been defined. 
• Product structures must have been defined for parts, and lead times must have been established for both purchased and manufactured parts. MRP only uses the existing product structure with the alternate denoted by an asterisk (*).
• You must have created a master production schedule using IFS/Master Scheduling or you should run PMRP. 
• If you want to perform multi-site MRP processing, you must first define a planning network in IFS/General Data for Inventory and Distribution as well as define multi-site planned supplier parts in IFS/Purchasing.

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

• Different subsets of the planning network can be planned at different times without losing important plans from the previous results. For example, MRP will remove unreleased distribution orders that were previously generated for the demand from the sites in the planning network.  Distribution orders with the demands from the sites outside the planning network will not be removed. 
• 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 was stopped. Warning indicates that a message posted for this process has to be reviewed by the user. This can be done by selecting the View Detail right mouse button option in the Background Jobs window, which displays the message in the status information table. If you decide to continue the MRP process, the MRP 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 generates purchase requisitions for parts that must be purchased. Shop order requisitions that are not converted into shop orders and 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 multi-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 Planning Network MRP window.
2. Enter the planning network for which you want to run multi-site MRP. Click List to select from the available planning networks. If you leave the field blank, the MRP process is run for all planning networks to which you have access.
3. Select the date on which you want the MRP process to execute. The current date is used by default.
4. Optionally, you can stop the MRP process when any error occurs.
5. Optionally, you can add 1-day lead-time back-off to planned receipts. 
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 Plan 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 the MRP process to capture the planned alternate parts, you can do so by selecting the Plan Alternate Components check box.
9. If you want to get the default values defined by the administrator in the Database Tasks window, click Default.
10. To run the multi-site MRP process, 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
