This article is part of the Tool Mastery Series, a compilation of Knowledge Base contributions to introduce diverse working examples for Designer Tools. Here we’ll delve into uses of the Error Message Tool on our way to mastering the Alteryx Designer:
A must-have for any app or macro, the Error Message Tool displays a prompt to the user based on input from Interface Tools. Using any expression that evaluates to true, along with any number of user inputs from question anchor connected Interface Tools, the Error Message Tool can layer even the most involved applications with failsafes that ease a user’s experience through more robust interactions. Failsafes like:
Ensuring Interface Tool values aren’t left blank (attached in Error Message 1.yxwz):
Standardizing/forcing user input to specific formats (attached in Error Message 2.yxwz):
Enabling more complex application/macro interactions (attached in Error Message 3.yxwz):
The example above uses windows environment variables to “authenticate” a user before using the app. Using the Error Message’s expression box creatively with other variables or constants from your (or your users’) working environment lends incredible breadth of functionality to the app developer!
By now, you should have expert-level proficiency with the Error Message Tool! If you can think of a use case we left out, feel free to use the comments section below!
