Date Selection Data Validation

[AlexOnTheHill]

I have been working on our change process and have spotted a few instances where the Business Process has failed due to requestors submitting a change to complete before the change is initiated.

We ask for when the work is intended to be started and when it is to be completed by and occasionally people select the same day and mistakenly think that midnight is the end of the day, rather than the start.

The business process then creates a task for the person processing that change with a start and end date determined by those dates initially selected so when an end date is less than the start date the process fails.

Is it possible to add validation to a date to say must be greater than a previously selected date?

Perhaps I am going about things the wrong way, if there is a better suggestion I am keen to hear it!

 

Many thanks
