Can I pin only one planning variable but not all?

[Kent Zhang]

Hello, teams,

There are more than one planning variables in the planning entity, I want to pin only one of them, but not all. Is there any way to impletement this case? In my opinon when I set the field that with @PlanningPin anotation to true, all the planning variables in this planning entity will be pin. Is it correct?

thank you a lot.

best regard!

Hey there,

as far as I know, you can only pin the entire entity, incl. all of its variables.

If you need more granularity, you could possibly implement your own selection filter, but that may bring issues of its own.

Thank you ! Lukáš.

Yes, I pin one of the planning variable by implementing the PinningFilter interface now.
