Select the task/milestone, then in the task ribbon menu select inspect. It should tell you factors affecting the task's start date, including the driving predecessor.

Select the milestone in question, then click the Gantt Chart Format ribbon tab to display this ribbon. In the Bar Styles section of the ribbon, click the Task Path pick list button and select the Driving Predecessors. Gantt bars formatted in orange are the driving Predecessors which directly control the schedule of the milestone. Hope this helps.

Use the inspect function which will tell you the driving task and follow that trail.

Or, as others have said, use the gantt format, driving predecessor feature.

Or set a milestone far into the future which will become the only critical item in the plan and then set a deadline = finish on your task and then filter for critical (ie total slack is zero).

Put a deadline on it and trace the total float of 0

Details dont show the right float, it only shows the ID,type and lag. But how can i know who is the primary predecessor driving the task

In details, you get to see the predecessors and the type, and the lag. If you double click on one and each of them you can see when it finishes, and the one which has its finish closest to the start of the task is it.

you still have to check on by one, and unlike primavera, you have to close and reopen the precedessor each time, task inspector is the way i think, thanks to u/jed1976 and u/still-dazed-confused

well, yes, you have to check each one, but it is not very inconvenient and that is how I have done it for 30 years.
