Immovable dates on a critical path

I’ve just created a critical path on my project board with dependancies. My deadline is fixed and shouldn’t be moved but when I update other tasks the date for this is pushed back. This is what I expect to happen, but I wonder if there’s a way to get the board to alert you when a specific date goes past the deadline?

Or alternatively shorten other windows of time rather than push back the final date?

The date in question isn’t a deadline but the date an event goes live so there’s no moving it!

Is this something that can be done?

hi @Rachael

Welcome to the community!. It looks like you are looking for a “Start-Finish” relationship (backward planning), that moves the start date of the predecessors. “Start-Finish” are not supported by the dependency column. Is this what you are looking for? Loom | Free Screen & Video Recording Software
