has anyone modified a workflow so that if an approved and posted Journal Entry is edited it shot back into the workflow requiring another approval?

wouldn't that just require a separate single state workflow that initiates the original approval workflow upon edit conditions?

ive done it with Vendor Bills

I'm pretty new to netsuite so I've been trying to figure out a lot of things. Could you share a screen shot of the parameters for the vendor bill one you've made @tjaffer?
