Graphic planning: provide days that are made grey by default

Related products: Software Factory

If you want to make certain days grey in a resource scheduler (for example the weekend), you have to write a view that provides these days for each resource. If you zoom out the schedule, this view contains a lot of records, which is bad for the performance. You should be able to provide days that are made grey (or another colour) by default.
Default disabled days can now be set in the scheduler. This way the colours for default disabled days do not have to come from the view, which wins performance.
