Date validation through automation rule

[Sushma Reddy]

I have a requirement to create a automation rule in jira cloud, to popup the error message by comparing two date fields.

For example consider "StartDate" and "DueDate". If "StartDate" has some value and if it is grater than "DueDate" it should give us a error message like (StartDate should be less than DueDate).

Is there a way to achieve this requirement?

Hello @Sushma Reddy 

Simply use a condition in the automation in which you compare the two field values.

It is not possible to create a popup with automation. You can write a comment that says, "Attention, DueDate is before the start date".

But what you are probably looking for is not automation but a validator in a workflow step see: Atlassian Documentation
