When you enter a criteria in the Release sales order picking to include the open sales line with a ship date till a specific date, you get a set of records in the form but the "All orders can be delivered" checkbox does not consider this filter and it's unmarked even if the other open sales line out of the date rage and there is quite enough stock to deliver the sales line that are currently appearing in the form. This makes the form not really useful as users have to verify one line by one and analyze the dates in order to know if there is enough stock or not.
