When a task is late in the status how can we set it up to show how many days it's late not just late? I want to see on each task how many days it's late.
Firstly you need to Baseline your plan at the start of the project, when all the planning has been done and you have a plan you are happy with.
Then add the Column 'Finish Variance' to your view.
Whenever the currently forecast Finish date is different to the date it was supposed to have been in the original forecase (i.e. the baselined plan), the difference will be shown in the Finish Variance column.
