We have a custom workflow for Vendor Bills. The Approve Bills page does not show the pending approval bills. So, I created a custom view saved search. It seems that I have to select every Pending Approval state, so that the Vendor Bills will appear? They don't show up automatically? I have to select an Action first on the Approve Bills page?

Turn off approval routing in accounting preferences. I had the similar issue.

But we have a custom workflow. When I turned it off, it doesn't show the Vendor Bills pending approval anymore in the Approve Bills. Can you still see the unapproved Vendor Bills in the Approve Bills page even if that's turned off?

Yes I see the list of unapproved bills in the list and on the reminders too. In your custom workflow make sure you are setting up the next approver. I read a SuiteAnswer where it said to set the next approver if using custom workflow with approval routing enabled.

I just tested it again and it seems that unapproved Vendor Bills created AFTER turning off the preference will appear. I'm just confused now. What's the purpose then of turning on the approval routing preference for Vendor Bills?
