When is end of life for the resource planner. And what will take it's place in terms of getting available hrs of a team

At present we export weekly reports from the resource planned to feed templates that visually pull together a weekly report

as this is the only way we can find to get Total Available Hrs, vs Planned Hrs Vs actual Hrs by week for a team

Attached examples

We need to understand when the resource planned is going to be removed and what will replace it is (Workload balancer) and how we get total available hrs a week by team

Many thanks Dan
