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 Data page will be considered
when creating the supplies by MRP.
Only the sites to which the users have 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 Show Details command in the
Background Jobs
page, 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
option in
Inventory Part/Manufacturing tab page is enabled.
- 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 on the
Inventory Part/Manufacturing tab.
