Production price variance

Hi,

I was wondering if anyone could confirm that this is standard AX functionality?

Before reporting as finished my production order I go to the standard route card journal and edit the hours to reflect production. If I was to then RAF and end the production order I don’t get a price variance.

However if I post the standard route card journal, then create another route card journal with negative hour lines in order to reflect the actual production, then RAF and end the production order - I then see a price variance in my price calculation.

Is this how AX should work?
