The ticket (Lclass name: Planning Element name: Function 1) before the
planned man-hour change is displayed in the ticket registration
information of the Redmine ticket interface.
The person in charge of "Lclass name: Planning Element name: Function 1" is
Eiji Ito, so only the person in charge can change the planned man-hours.
Set the planned man-hours to 180 hours.
After starting up, the team leader (in this case Katayose) will reflect the
information edited by each person in charge in Redmine.
Click "Update Process".
The planned man-hours will be updated and the ticket will be processed
(green).
