## Purchase Order Approval Workflow

The purchase order approval workflow defines how many levels of approval a PO requires, who is responsible at each level, and the cost threshold that triggers each level.

## How Approval Levels Work

Each approval level activates when a PO’s total cost meets or exceeds that level’s **Cost Threshold**. You can add as many levels as you need and reorder them by dragging.

## Configure the Approval Workflow

1. In ION, go to **Settings > Supply Chain > Purchases**.
2. In the **Approval Policy** section, click **Add Level**.
3. For each level, fill in the fields:
   - **Role**: the role you must have to approve at this level.
   - **Team**: the team responsible for approvals at this level. Can be left for you to select at review time.
   - **Cost Threshold**: the minimum PO total (in your org’s currency) that triggers this level.
4. Drag levels into the order in which you want approvals to happen.

## Configure Approval Reset Thresholds

If a PO is edited after approval, ION can automatically reset approvals and require the workflow to run again. Set this in the **Approval Reset Cost Threshold** section:

| Field               | Description                                                                      |
| ------------------- | -------------------------------------------------------------------------------- |
| **By Percentage**   | Reset approvals if the PO total changes by this percentage.                     |
| **By Amount**       | Reset approvals if the PO total changes by this amount in your org’s currency.  |
| **Condition**       | Whether both thresholds must be met ( **and**) or either one is enough ( **or**) to trigger a reset.
