Presently Service order validity exists at Site wise schedule. User has to provide Valid from and valid to date for every site at line level. This validity typically required for orders which has a nature of Recurring Invoice. But for one time Order for any service did not require this validity.
Now this Valid from and Valid to is mandatory. Need to make it optional.
We assume that no Order should be generated without having any due Date mentioned to it. So user has to mention Due date even if it is closed/delivered in same day. I hope you understand our concern.
