Is there a way to enter total of hours (free entry of actuals) for each task that can be calculated automatically for the summary task in the Gantt view if we aren't using timesheets in Clarity PPM?
The one option available to enter hours using free entry would be to use one of the scheduler tools Open Workbench (OWB) or Microsoft Project (MSP).
The steps below walk the user through steps using MSP as an example, but similar steps could be used for OWB:
Prerequisite: Make sure % Complete calculation method of the project is set to “Manual” (Which is the supported calculation method in working with schedulers). Important: It's not supported to change this value once a project has started as it can impact data on tasks including status.
