Power Automate PO Approval with Multi-Entity Policy

Das Problem

Validate purchase orders in Power Automate against entity-specific approval thresholds, vendor approval lists, and budget availability before routing — without maintaining complex approval matrices per entity.

Einrichtungsschritte

1. 1

   Import Corules Custom Connector to Power Platform

2. 2

   Configure entity-specific parameters in Corules admin (AU thresholds: $10k/$50k/$100k, EU: €8k/€40k/€80k)

3. 3

   Add Corules 'Get Constraints' action to PO creation Flow to retrieve required approver level

4. 4

   Route the PO to the correct approver based on returned constraint (manager / director / executive)

5. 5

   On approval completion, call Corules 'Validate Decision' with approver identity for audit log
