does the "IMPRESSION TO FAX" rule work if its the only rule?

That's a good reminder of how to simplify the test. It did not work when it's the only rule.

it would be good to have a look at the business rule log

I did look at it, or rather thought I was. I looked again this morning and there were errors. I must have accidentally opened the event log on the wrong process yesterday. Thank you for the sanity-check!

Thank you, Eduard! This is really interesting. It looks quite a bit more verbose.

Thank you, Robert, that is exactly what I was looking for!
