P5 Variance in Summary level ---Original Duration

Hai Friends,

I am a new user in P5 & we are using different calendar (7days/week calendar and 6days/week).My default calendar in enterprise level is 7days/week.Now the issue is when i am summarizing in activity code level, original duration is shown according to Default 7days/week calendar. But i assigned 6days/week calendar for all activities under that particular activity code level.

Can anybody explore and resolve this?

Thanks,

Jiso
