I am working in ModelBuilder in ArcGIS Desktop. I want to stop models from working when the current Time is greater than the project over time. Below snap showing where I am making a mistake please help.
I have not tested this but you could try using an
if statement in a Calculate Value tool to issue a
sys.exit() if today's date is greater than the date you want your model to cease working.
Then make that tool element a precondition to the rest of your model running.
Alternatively, as commented by @BERA:
You could rename or delete the Toolbox (*.tbx file) using a script in the operating system which executes at the desired date.
