OK, bigger picture. From your original post:
"Rather than have the end user input a date.... I've only got a designer license, not working with server...."
Does your end user have Alteryx Designer? If not, then you're the end user.
If they do, then you can turn this into an analytic app that they run. Or you could just give them the workflow.
From a subsequent post:
What is this?
Where do the manually updated rows come from? If it's just a few fields making up one row of data, then create an app and use Textboxes for input. If a file, like a spreadsheet, and a different spreadsheet for every run, then an app with a File Browse. Or just keep running the workflow and make edits when needed.
I don't know your exact situation so please consider everything a suggestion, a musing if you will. I would not want to give you advice that you then follow. :smiley emoji:
