Approval activities can be used if approval engines are not turned on for the table associated with the workflow.\n\nApprovals can be managed by approval activities or approval engines, but not both. Trying to use both can cause a range of issues. Approval activites are not available \\(greyed out\\) in the palette if approval engines are used on the specified table. If you hover over a greyed out approval activity in the palette, a comment with more information is provided.

Navigate to **All** > **Workflow** > **Live Workflows** > **All Contexts**.\n\n2.  Click the date and time in the **Started** column for the workflow that is incorrectly processing approval activities.\n\n3.  In **Related Links**, click **Show Workflow**.\n\n4.  Review the portion of the workflow that executed, and then do one or more of the following:\n\n    -   Verify that after approval, the workflow progressed to the next activity. If a workflow failed to progress, check the business rules. For more information, see [Debugging business rules](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/api-reference/scripts/r_DebuggingBusinessRules.md).\n    -   Point to each processed approval activity to find activities where the **State** is **Finished** and **Result** is **Skipped**.\n5.  Navigate to **Workflow** > **Workflow Editor** and open the workflow.\n\n6.  Double-click the skipped approval activity.\n\n7.  Click **Users** or **Groups**.\n\n8.  Assign an active user or group for the approval activity.
