Have a scenario where the maintenance windows are fixed per equipment. (e.g. Equipment A has scheduled stops every Wednesday, equipment B between days 10 and 14 every month, and sometimes those windows are known but not based on a fixed rule). This way, setting Date From and To on the Work Order is counter-productive, as resources might not be available on the next window, but maybe on the following one (which could be outside this single date timeframe). Ideally assignments would be done using RSO.
The maintenance windows are dates where the equipment would be turned off anyway. If there are any orders to be executed for this asset, they must be inside one of those windows, but most of the timeframes won´t have any orders happening. No orders may be scheduled outside an available maintenance window.
