Requirement related to multiple constraints

[daniel.piret]

Hello Support,

We know that currently there is only one constriant type and constraint date. Our requirement is to have a constraint for date range i.e. task should not start later than a date and should not end before another date.

Can you please let us know if this is possible?

Hi daniel.piret,

Not supported out of the box. Try to implement yourself, check HasDateConstraintMixin and ConstrainedEarlyEventMixin classes, they contain the logic to handle it.
We can help you with that if required, contact our sales for details: https://www.bryntum.com/services/

I'm looking for a similar solution, something that can constraint events within a date range, do we have a solution for this now?

That would need a bit of custom development to be supported at the core. If you're interested in sponsoring such a feature, please reach out to our sales box and we can discuss.

Thank you for your quick reply. I was checking out your previous comment - viewtopic.php?p=97283#p97283 - Do I override these classes -HasDateConstraintMixin and ConstrainedEarlyEventMixin ? How do you suggest I use these classes to support multiple constraints?

Hi dphilip@kinaxis.com,

Did you check the code of the classes already? These classes contains implementation of current constraints logic. You'll need to adopt that to support many constaints, after that add UI to manage that and check if Engine will handle it out of the box of also will require some customization.
These are not trivial questions about internal customizations that require deep diving into the issue to assist you here. I am afraid it cannot be done in bounds of forum support, but our dev team can help you as Professional Services assistance. https://bryntum.com/services/
