# Set up an approval engine

To manage the approvals for each of the Task tables in the system, set up an approval engine.

**Important:** Classic approval rules have been replaced by the Workflow Studio [Ask for Approval action](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/build-workflows/workflow-studio/ask-approval-flow-designer.md). Use Workflow Studio to create workflow-driven approval logic that is easier to maintain and provides better reporting information.

## Before you begin

Role required: none

## Procedure

1.  Navigate to **All** > **System Properties** > **Approval Engines**.

    The following page appears with the **Approval Engine** option for each Task table in the system. If the **Approval Engine** option is greyed out and shows **Turn engines off**, read the **Notes** in the same row. The most common reason an approval engine is turned off is that a workflow is managing the approvals on the table. Having the approval engine turned off prevents conflicts with the workflow that could cause a range of issues. If you want to use an approval engine on the table, set the workflow to inactive.

2.  Select the [approval engine option](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/build-workflows/approvals/c_ApprovalEngines.md) for each Task table from the choice list.

3.  Click **Save**.

    These preferences are saved as system properties that are named **glide.approval\_engine.<table\_name>**.
