SmartFlow APS Learn Center
Finite-capacity production scheduling, explained properly — for planners learning the craft, Business Central users and evaluators, and anyone using SmartFlow APS.
Learn the Craft
Product-agnostic education in production scheduling — finite vs infinite capacity, constraint-based scheduling, sequence-dependent setup, and more. Useful whether or not you run Business Central.
Scheduling in Business Central
What Business Central actually does — and doesn’t do — for production scheduling, explained mechanism by mechanism.
Using SmartFlow APS
The product user guide: the Gantt scheduler, drag-and-drop rescheduling, sequence optimization, setup reference, and more.
Getting started
New to SmartFlow APS? Install it from AppSource, then work through these in order — each one builds on the last.
- 1 APS Setup Reference Open the SmartFlow APS Setup page and set your timeline window, refresh interval, and frozen horizon. Defaults work for most shops.
- 2 Explore SmartFlow APS with the Built-In Demo Datasets Generate a self-contained demo shop so you can see a loaded board immediately, without touching your own production orders.
- 3 The Gantt Scheduler Learn to read the board — status colors, the capacity heatmap, the order-detail panel, and the sortable Grid view.
- 4 Your First Finite Schedule in SmartFlow APS Run a finite-capacity schedule end to end: generate a proposal, review the before/after KPIs, then accept or reject it.
Flagship guides
The definitive explanations of the mechanisms that actually decide a production schedule.
Finite vs Infinite Capacity Scheduling, Explained Properly
What infinite-capacity scheduling does and does not do, why it double-books machines, and what a finite scheduler guarantees instead - with a worked example.
Business Central Is Infinite-Loading: What That Means
The exact mechanism behind BC's biggest scheduling gap — why it warns about overloaded work centers instead of preventing them, and the one narrow exception.
Constraint-Based Scheduling: How Modern Solvers Model a Factory
How a solver turns machines, operations, and shift calendars into mathematics - intervals, no-overlap, cumulative capacity - and why soft constraints matter.
Sequence-Dependent Setup: The Changeover Matrix Explained
Why job order changes how much time you lose to changeover, how an asymmetric matrix models it, and why sequencing blind to due dates backfires.
Why MRP Is Not a Schedule
MRP tells you what to make and roughly when. It never decides which job runs first on a shared machine. The exact gap, and why more MRP runs won't close it.
What Is an APS (Advanced Planning & Scheduling) System?
A plain-language definition of Advanced Planning and Scheduling, where it sits between ERP and the shop floor, what it actually does, and where its limits are.
