The Project Tasks master data contains information about tasks related to the company's external and internal projects.
Before creating project tasks, it may be necessary to first generate master records for the following types:
Each project has its list of tasks, which can be seen on the project master on the project WBS page.
Main flow of new tasks creation is creation from estimation document (structure mode), wh ere we have special buttons.

To add a project task, select the Create button from the toolbar. To modify an existing task, double-click the corresponding line. Alternatively, right-click the desired line and choose Edit, or use the toolbar by selecting More actions → Edit.
This tab displays key details about the task, including the associated project and its planned start and end dates. As the project progresses through its lifecycle, the task's actual start and finish dates can also be recorded.

The Description and Project fields are mandatory.
Use the Milestone checkbox to mark this task as a milestone within the project.
Specify the planned start date in the Planned Start Date field and the expected completion date in the Finish field.
The Start Date (Plan) and End Date (Plan) fields allow you to define the planned duration of the task.
Once the task has started or been completed, the Start Date and End Date fields can be used to capture the actual dates.
Use the Details text box to add any relevant information about the task
