I have a vendor record that is active, but the custom field "Vendor Approval Status" is not flipping to approved (it is stuck in Pending Approval). I tried to edit, deactivate and reactivate my Vendor, but it does not seem to impact this field. I attached a picture of the Vendor Approval Status and the Workflow. I don't know how to "reboot" this for vendor approval, but you can see that in theory once we flip Inactive to "F", it should go to Approved Vendor Status.

I understand that the vendor is stuck at "pending approval", but is the workflow on the vendor currently active/in the 'pending approval' state?

The workflow, if I understand your question correctly, is still working fine. The vendor is active and has transactions against their account. Also, all other vendors come through and get processed correctly. I believe what happened is an accountant who left the company is still listed as the vendor approver at the time, and somehow we superseded that person to get this account approved. However, this custom script got stuck somehow...

very hard to diagnose without having access to the record and workflow. My only advice would be to potentially cancel and restart the workflow to get it, and the 'vendor approver' field, back in to a valid state

how do I do that?

NS Help: Canceling a Single Workflow Instance You can sometimes instantiate a workflow by hand (it's mentioned in the above help article), otherwise you can use a mass update to target the specific record: NS Help: Mass Initiating Workflow Instances

@David B You are awesome! I did the steps above to cancel; i then edited the vendor and replaced the approver name et voila! Good on you, mate! Have a great day.
