Question

Hi All

Greetings!!!

I have alteryx app where I have selecting the file using file browse option and run my workflow.

But if file does not exists then I don't want to run the app. Process should be stop by pop up the message box saying "File or Folder does not exist"

and my app run will automatically stop.

Please help me on this. Its really appreciate if you could help me on this.

Thank you in advance

Hi  @alt_tush

Look at using the Message tool from the Developer toolbar.  you can configure it to error and stop the workflow based on a condition.
