Using An Output as An Input in Alteryx

Using a workflow output as an input in the same workflow can be tricky. How do you make sure the output is completely written before being used as an input? A few months ago, I showed how the CReW macro tool, Parallel Block Until Done, can be used to control the order of operations in a workflow so that the output is fully written before the input is used. The CReW macro creator, Mark Frisch, reached out to me recently to tell me that my solution wasn’t wrong, but that there was a simpler way to achieve the same task. He bestowed some sage Alteryx wisdom upon me, and now I want to share it with you. Thanks Mark! Read on to learn more.
