I was wondering if anyone has had to deal with a workflow approval process that needs to have actions occur based on line values. I created a test script to capture a field value when it moves from entry to pending in a workflow field named oldValue, but after approval occurs if any changes happen it will save the value in a field named newValue and then there is a transition to un-approve if oldValue != newValue. Now it works, but seems like a really clunky way to do this especially if I want to capture more than a single line field. I was interested to hear how other people handling workflow approvals that need actions to occur when line level actions occur.

compare values from the old record to the new record
