I have a workflow that sends an email when a field value is changed on a salesorder. This works fine and the email is sent. I am now needing to add the old value for the field and am not sure how to do this. I tried using {old.custbody_myfield} and {oldrecord.custbody_myfield} but neither is working. Is there a way to show that old value in the email body?

I am not aware of anyway to access the "old record" in field values. I know you can do it in conditions but not in setting field values. You could try to make another field on the sales order that holds the "old value"

Thanks. That seems to be the only solution.

Couldn’t you use the systems notes to show the old value and the new value when it changes?
