Set up 10 day shift cycle

[Ronan]

Hi,

First post! I'm having real trouble setting up a 10 days on, 4 days off shift cycle in Project.

I've tried to set the working week to 7 days all working, and then setting an exception for 4 days each individually to recur every 14 days but Project won't let me do that. It says they overlap or something.

Any ideas/suggestions?

Thanks!
