Pending
1. Each newly created order will have assigned status "pending".
2. "On save" shouldn't be data validation. Order could be saved without planned from-to date (somebody will create order, but the date will be calculated later)
3. If it exists connection between MES and ERP (eg. enova), date validation shoul be active only for "date to" (the assumption is that ERP provides this date).
4. The icon "Start" should be replaced by icon "Accept" - graphical proposition is following (please use the icon "Start", which will be replaced by new one).
5. The date & time and worker, who created record, should be registered (see: "order details" tab)
