A Truth Table within the Rule Set will run to confirm each account has a designated Company and Job Title. The output from the Rule Set is passed to the True/False rule to stop the Flow on the first false. Below is a downloadable example to [import](/v9/docs/importing-and-exporting-projects) into Decisions.
