How can I make a workflow that checks if a sales number already exists on save? Do I need to use a workflow action script, or is there a built in way? We use auto generated numbers, but need to allow overrides. So if two orders are generated at the same time, they wind up being saved with the same number currently.

You'd have to use a workflow action script in which case, I'd just recommend a client script.

got it. Thanks
