Handling Division Failure

Reza Rad looks at how division can go wrong in Power Query:

In this example I just returned zero if I find error. but you can return error message if you like with [Revenue Per Item][ErrorMessage]. This method is great error handling method when an error out of blue happens in your data set. I always recommend using TRY method to get rid of errors that might stop the whole solution to work properly.

I have to mention that steps above are separated to show you how the output of try expression looks like. In fact you can combine both steps above in single step with TRY OTHERWISE as below (Thanks to Maxim Zelensky for pointing this out);

The end result is code which is a bit more complex, but safely handles a number of edge cases.
