SCM APO Constrained plan

[Former Member]

Is constrained based plan possible in R/3 or not if so what is the difference or benefit in APO.

In my openion in R/3 side constrained based plan is not possible rather it takes place in SNP CTM or Optimizer. plant location one at a time with demand priority with CTM gives feasable plan. In Optimizer best feasable with cost constraints accross the network.

Hi

Hope this would help

Unconstrained vs Constraint-Based Planning

R/3 PP

Infinite material & capacity planning

Creates unconstraint plan

Creates feasible schedule

Sequencing by overall setup time within day

Simulation is for long term planning

Backward scheduling logic only

Due date driven planning

Manual Capacity Leveling

PP/DS

Finite capacity & material planning

Constraint-Based Planning

Uses Optimization to create schedule

Minimize = total LT + setup time + delay time + production cost + setup cost

Simulation is fast real-time, “what if” planning capabilities

Forward & backward scheduling

Customer priority, cost, driven solution

Scheduling Algorithms

Detail Capacity Planning
