This requirement describes a conditional approval workflow. In Consumer Goods Cloud TPM, the lifecycle of a promotion (Draft -> Submitted -> Approved) is governed by the Workflow engine (State Machine).

When a KAM attempts to approve a promotion that exceeds a spending limit (e.g., >$50k), the system must prevent immediate approval and instead route it for review. This is handled by aState Transition.

Transition Logic:You define a transition from 'Draft' to 'Submitted for Approval' (or a specific review status) that triggersonlywhen the condition Plan Spend > 50,000 is met.

Workflow Action:Attached to this specific transition is anAction. In this case, the action is to 'Send Email.'

Therefore, Option B is the correct configuration. You configure theWorkflow State Transitionto detect the threshold and automatically trigger theEmail Actionto the approver. Option A (Validation Action) is typically used toblockan action entirely (e.g., 'Error: You cannot save this promotion'), which wouldn't facilitate the routing process to the approver. Option C (API) is a custom development approach that is unnecessary given the standard Workflow functionality.
