MRP Master Production Schedule

In Make-To-Stock scenario, the “Master Production Schedule” process is part of the overall planning process and is fully integrated in the overall Openvalue manufacturing planning and execution solution.

The Master Production Schedule aims to ensure material availability and to increase planning stability.

This is achieved by setting products, which greatly influence company profits or which take up critical resources, as MPS relevant; this allows to check and to plan them separately in MPS process.

The planning of MPS products greatly influences the entire production planning process, even if they represent a small share of all the products to be planned.

The MPS planning run only plans the products set as MPS relevant; dependent requirements are created for the BOM level directly below the MPS planning level; however, this level and lower levels are not planned.

Frequent their changes can render the complete MRP run unstable. Therefore, the MPS parts are to be planned in a separate way before planning all the other products.

The MPS planning run in the overall planning process

·        performing the planning run for master schedule items, i.e. MPS planning engine run; the MPS planning run only plans the products set as MPS relevant; dependent requirements are created for the BOM level directly below the MPS planning level; however, this level and lower levels are not planned;

·        Once the “Master Production Plan” has been finely tuned for the master schedule items, performing the planning run for all remaining dependent parts, i.e. MRP planning engine run.

Total Replenishment Lead Time

The “Total Replenishment Lead Time” is a new planning parameter set at parameter master data level.

A check has been implemented to avoid entering Demand Items in the Demand Management with planned date before the Total Replenishment Lead Time.

This is to protects “frozen” Master Production Schedule and ensures a production process stable.

Rough Cut Capacity

Workcenters capacity constrainted are to be set as relevant for Rough Cut Capacity evaluation. Therefore, only the main workcenters take part to the rough-cut capacity process.

In the MPS planning run, MPS planned orders are automatically scheduled for determining MPS capacity requirements to be compared with the available capacity; the MPS capacity requirements are determined for Rough Cut capacity workcenters only.

for manufactured products, their routing is taken into account for determining the capacity loading.

for subcontracted products, a workcenter and a time cicle can be assigned to a subcontractor at supplier info level.

In case the scheduling finish date falls after the order due date, a planning note is issued in the MPS planned order list.

This is to alert the planner the manufactured order related to the conversion of the concerned planned order will have an inconsistence between planned pivot dates and scheduled dates.

A MPS capacity can be leveled by changing the planned dates and/or quantities in planned orders.

Capacity Evaluation

The capacity loading can be evaluated on weekly basis through a table pivot view, available for RCC workcenters

Master Production Schedule

After leveling rough-cut capacity plan, that’s after performing the rough-cut capacity process, all relevant planned orders can be frozen and collected by a Planning Version.

This is the Master Production Schedule. At Planning Version level, revenues and costs are determined for performing a financial evaluation for the concerned master production Schedule.
