I'm building a model where users can input the dates when they complete certain training events, and then taking that information and creating visualizations/analytics off of it. In order to keep the data clean, is there a way to prevent the user from selecting a date in the future since I only want to deal with actuals in this instance?
Yes there are many ways to place security for users ,depends where you wana restrict them and on which dimensions ?
Go through user security lessons in community you would be able to judge what type of security you can have in place . In brief you may want to restrict users here with the help of DCA . create drivers and restrict users accordingly
Yes and no. No, in the fact that if a user inputs an invalid date, we don't have a way to "clear" it out automatically or prompt them for a valid date. With that said, there are a couple of ways you can get around this.
The easiest way is to use conditional formatting to highlight the line item in red (or color of your choosing) if the date falls outside of the threshold. Also, create a boolean to be on (True) if the date is valid and now downstream calcs and reference the boolean as well as filters for views.
Another way is to have a list of days that can be used, but this can be cumbersome as well as a maintenance hassle.
