Percentage - how to default a blank to 0%, rather than 100%?

[Jumper]

Hi.

I'm trying to clean up a sheet I have inherited from my predecessor.
It involves a very basic Dax formula that the company uses to calculate staff productivity:

Productivity =
DIVIDE(
|     SUM('Employee_Hours'[Job_Hours]),
|     SUM('Employee_Hours'[Hours_Rostered)
) + 1

The problem with this formula is that if an employee has registered zero hours, then their productivcity defaults to 100%.  0% would be the preferred default, if that is possible. 

My dax skills are pretty basic that a solution immediately jumps out at me here - is there a better way to write this formula?

Hi @Jumper ,

Try to modify your formula like below:

Productivity = 
IF(
    SUM('Employee_Hours'[Hours_Rostered]) = 0,
    0,
    DIVIDE(
        SUM('Employee_Hours'[Job_Hours]),
        SUM('Employee_Hours'[Hours_Rostered])
    )
)

Brilliant - this works perfectly.

Thank you so much, and sorry for a slow reply (had a few days off!).
