I've obviously been doing lots of work with APIs for this to be my second idea posted today which relates to an improved based on recent work with APIs, but I also believe this is wider reaching.
I've been using Alteryx now for over 4 years and always assumed implicit behaviour of the select tool, so would add a select tool as best practice into a workflow after input tools to catch any data type issues. However I discovered that only fields where you either change the data type, length or field name result in that behaviour being configured and subsequently ensured. I discovered this as part of API development where I had an input field which was a string e.g. 01777777. Placing a select tool after this shows this is a string data type, however if the input was changed to 11777777 the select tool changes to a numeric data type. Therefore downstream formulas such as concatenating two strings would fail.
The workaround to this is to change the select tool to string:forced, which is fine when you know about it, but I suspect that a large majority of users don't. Plus if you have something like 2022-01-26 which is recognised initially as a string, then the forced option will be string:forced, however if you wanted it to be date:forced you need to add a first select tool to change to date, and a second select tool to change to string:forced.
Therefore my suggestion is to add a checkbox option in the select tool to Force all field types, which would update the xml of the tool and therefore ensure what I currently assume would be implicit behaviour is actually implemented.
