Source · Planner · MES — one production loop
Three elements close the path from order to settlement: the parent system says WHAT to produce, the Planner arranges WHEN and WHERE, and MES records what was actually made.
These aren't three separate tools, but one flow. The Source delivers the plan, the APS Planner turns it into a feasible schedule and sends it to MES, and MES returns the actual progress — which flows back to the plan and to settlement in the parent system.
MES on the shop floor — live OEE, output and downtime
Operators report progress and the system shows OEE, a workstation timeline and top downtime — data flows back to the planner.
Three elements and their roles
Source (ERP)
Role in the loop: Delivers the plan to the Planner and takes production results back for settlement.
What it does: Defines what needs to be done, in what quantities, along which routing and by when.
Production Planner
Role in the loop: Turns the plan into a feasible schedule and publishes orders to MES; reads progress.
What it does: Schedules operations across machines and people over time, optimizes for the goal, shows the timeline and "what-if" simulations.
MES / shop floor
Role in the loop: Receives orders, records real production and makes progress available back.
What it does: Operator terminals: reports of good pieces and scrap, downtime, changeovers, quality; calculates OEE and builds batch genealogy.
Closed loop: plan → production → settlement
Each stage feeds the next, and the result returns to the start — data circulates without manual re-entry.
Plan
The Source and Planner decide what and when to produce; the released schedule goes to MES.
Production
The shop floor reports actual execution in MES — good pieces, scrap, downtime, quality.
Settlement
Progress returns to the Planner and to the parent system, closing the plan and settlement.
Why it works
Data consistency
One flow instead of three information silos — plan and execution match.
No manual re-entry
Orders and results circulate automatically between the layers.
Data-driven decisions
Actual shop-floor progress returns to planning immediately.
From plan to settlement
The complete order journey closed within a single loop.

FAQ — Source, Planner and MES
- What is the "source" in this setup?
It is the parent system (ERP) where projects, orders and operations are created. It is the source of truth about what to produce, and it takes production results back.
- How does data circulate between the elements?
Source → Planner: load the plan. Planner → MES: send orders. MES → Planner and source: progress and results. The Planner↔MES exchange happens via a REST API.
- Can the elements work separately?
Yes, but they deliver their full value together — only when connected do they form a closed plan → production → settlement loop.
