In the Project plan (Work Breakdown Structure Form) of D365 For Operations, it is allowed only to set Finish-Start lag, which forces the dependent tasks in a project plan to start immediately after the predecessor task.

There should be functionality to add different lag types to predecessors, such as Number of days, Calendar hours, percentage of a time frame etc. This will allow to setup tasks where dependent tasks can start after a certain lag time has passed after the predecessor task is completed.
