A business rule is a constraint Solya evaluates before a plan action. A ruleset groups rules; one ruleset is your organization’s default and applies whenever a plan doesn’t specify another.

​
Anatomy of a rule

  • Category — the domain it belongs to: capacity, assortment, ordering, transfer, pricing, distribution, or compliance.
  • Enforcement mode — what happens when it triggers:
    • Block — the action is rejected.
    • Warn — the action proceeds with a warning.
    • Log — the firing is recorded silently.
  • Check level — what it evaluates: shop, brand, product, variant, inventory item, plan, or plan item.
  • Condition — the test (a threshold or value), backed by live data fetched at evaluation time.
  • Scope — which shops, brands, suppliers, products, variants, or collections it applies to. An empty dimension means “all”.
  • Validation hooks — the moments it fires (see below).
  • Violation message — the message shown when it triggers.
  • Priority — the evaluation order.

​
When rules fire — validation hooks

Rules are attached to hooks that fire at specific points per plan type:

​
Templates

Rather than building rules from scratch, start from a template in the catalog — e.g. max plan value, max items per shop, max quantity per variant, OTB envelope caps, size-curve deviation, markdown discount/margin guards, and supplier policies. Pick a template, set its threshold and scope, choose Block or Warn, and assign it to a ruleset.

​
Working with rules

1

Open the Business Center

Go to Intelligence layer → Business Center / Business rulesets.
2

Create or pick a ruleset

Create a named ruleset (e.g. Strict Q4), or edit the default.
3

Add rules from templates

Instantiate templates, set thresholds and scope, and choose the enforcement mode.
4

Set the default

Mark one ruleset as the organization default.
5

See them in action

Blocks and warnings appear in the plan’s validation panel as you build plans.
Every rule evaluation is recorded, so you can review which rules fired on a plan and why. For the technical model (hooks, enforcement, paradigms, phases, the operations layer), see Business rules engine.
