Thank you for your answer. Can you tell me how can I access to operation model and a field called "operation time in hour" ? I cannot seem to find that field. Also, If one my operations takes let say 1200 minutes and  I want to convert it to hours. What kind of calculation I put to default duration field? (1200/60?)

Hello,

Currently there is no any option to enter the operation time in hour. But you can do that you have to apply some changes inside operation model. You have to take a field for operation time in hour, and you have to put the calculation on default duration field. So it converts the hour into minutes and set in default duration field.

Thanks,
