I will start off with a story. I have built a process to manage batch API requests. It's an iterative process that checks to see where the export is at by calling an API and then returning some status. It will run and wait and run and wait until the export is ready to be downloaded. However sometimes, the jobs don't finish and a status returns something like "failed" or "cancelled". When this is the case, I have my process (which is a little bit batch macro) kicks off an error message, using the nifty error message tool. After some time I noticed that it was a PAIN to go back and figure out which of my requests failed and I decided that I need to add some messaging around where this was failing, so I could do some easy auditing. So I go back into my tool and much to my chagrin, I cannot pass variables into the message section. I would expect it to have worked something like this:
"Record "+[#2]+" is not 'A'"
Can we please get a change to this. It would save a lot of time and energy if we could create a dynamic error message option.
TL;DR Please allow us to use formulas in the "If expression is true, display error message:" settings area.
