Request for MS Project‑style Actual Date Logic in Bryntum Gantt

[sagarshivgan]

Hi,

I’m working with Bryntum Gantt (JS) and noticed that it doesn't provides fields for Actual Start and Actual Finish and it's logic like in Microsoft Project (MPP).

In MS Project, once you apply actual dates, the task strictly follows those actual dates only — it no longer considers scheduled dates, dependencies, or constraints. This ensures that progress tracking reflects reality rather than planned logic.

In Bryntum Gantt, however, this behavior seems to be missing, which leads to inconsistencies when compared to MPP and makes accurate project tracking more difficult.

Could you please clarify:

• Is there any built‑in option to enforce MS Project‑style actual date logic in Bryntum Gantt?

• If not, would you consider adding support for this logic in future releases?

• Alternatively, is there a recommended way (via API hooks, event listeners, or configuration) to implement custom rules so that tasks with actual dates ignore planned scheduling and constraints, just like in MPP?

This feature would be very helpful for us as we rely on strict project tracking and need seamless integration with MS Project.

Thanks for your guidance!

Thanks & Regards,
Sagar Shivgan

Hello,

Yes we have plans on implementing Actual* fields support in the Gantt. The ticket is here https://github.com/bryntum/support/issues/2558

So far the closest feature in the Gantt is baselines. But all it provides is just visualizing of planned dates.

Alternatively, is there a recommended way

I guess just a general adding of new related fields + tracking their changes and updating related values.

Best regards,
