On the SRM there should available date validation so it can be used on MyIT. As we have option for Regular expression on the Text fields.
1. Date field validation - like, you have "Start date" and "End date" fields on the request create dialog on MyIT, and you want to validate those dates, so "End date" can be only GREATER THAN "Start date". That should work immediately after entering dates, without clicking on Save.
2. Start Date shouldn't be entered smaller than current Timestamp option also after entering dates, without clicking on Save.
