Variant constants

Variant constants are four per-variant overrides: Min Inventory, Max Inventory, Target Inventory, and Static Reorder Point. Use them when a SKU should be constrained by your business rules — a product you never want below 50, or never above 500.

What variant constants are

Per-variant numeric overrides, one set per variant (or per variant × location). They tell Logistified your business limits for stock at a given location:

Min Inventory — the smallest stock level you want.
Max Inventory — the largest stock level you want.
Target Inventory — the level you refill to.
Static Reorder Point — a fixed reorder point you set yourself, instead of the model’s computed one.

Optionally configurable per location too.

Where to set them

Variant constants live on a dedicated settings page: Settings → Products → Variant Constants. A grid where you can edit many rows at once, or import via CSV/XLSX through the unified import flow.

The forecast page only displays the constants — the Min / Max / Target / Static Reorder Point columns are read-only there. You can’t edit a value by clicking the cell on the Forecast page; head to the settings page to make changes.

Cross-field validation

Logistified enforces three rules so the values stay internally consistent:

Min ≤ Max
Min ≤ Reorder Point ≤ Max
Reorder Point < Target ≤ Max

If a rule is violated, the row turns red and the save is blocked until fixed.

How they show on the Forecast page

The In Stock cell renders a read-only colored fill bar with markers at Min, Reorder Point, Target, and Max. Hover for the breakdown. The bar color signals where current inventory sits:

Color	Meaning
Red	Below Min.
Orange	Between Min and Reorder Point.
Yellow	Between Reorder Point and Target.
Emerald	At or above Target (still under Max).

Variants without configured constants render the bar with default markers — you’ll notice the difference once you start setting them.

What they do not do

Variant constants are display + alerting only for the forecast page. They don’t change the forecast model’s reorder math.

The reorder math (Reorder Point, Reorder Date, Reorder Quantity) uses the forecast model’s computed values plus the supplier link’s lead time, MOQ, and pack size.
Static Reorder Point is only used for threshold filters and the In Stock cell. The forecast still computes its own reorder point in parallel.
Min / Max / Target are consumed by the separate “Create PO from min/max” workflow on the Suppliers list, and by the “Create TO from min/max” workflow under Transfer Orders.

Bulk import

For larger catalogs, use the import flow. Settings → Products → Variant Constants → Import. Map columns, preview, commit. See Guides → Import data (CSV/XLSX) for the full walkthrough.

The bulk grid and the import flow are the only ways to edit variant constants — there’s no inline-editing path from the Forecast page.
