Hello,
The feature of using the task progress when auto-scheduling tasks was added in the 8.0 version:
https://docs.dhtmlx.com/gantt/whatsnew.html#:~:text=new%20auto_scheduling_use_progress%20property

https://docs.dhtmlx.com/gantt/api__gantt_auto_scheduling_use_progress_config.html#:~:text=Change%20log-,added%20in%20v8.0,-Back%20to%20top

So, you the 7.1.13 version doesn’t have that feature.

If you want to cancel auto-scheduling for a specific task, you need to return false in the onBeforeTaskAutoSchedule event handler:
