Workflow Deal Stage Advancing Only if all Tasks are Completed
I'm trying to build a workflow that will check to make sure all tasks are completed in the current Deal phase before automatically advancing the Deal to the next phase.
I've found that the conditionals don't work for this specific scenario if I try to filter based off the activity (task) subject name. I can do it for 1 activity, but it's not possible to do this with multiple activities because it isn't possible for the activity subject to match both activity names simultaneously.
Is there another or better way to accomplish this?
