There is usually more than one way to do this. A lot of measure are built upon other measures, branching out.
I'm using my own made up data but should apply to yours if you change the table name and column names.
You'll see, but the measure for the % complete is:
Perc Complete = DIVIDE([Completed Jobs],[Total Jobs],0)
Incomplete Jobs = CALCULATE([Total Jobs], JobStatus[Status]="INC")
Completed Jobs = [Total Jobs] - [Incomplete Jobs]
