Change Request Date Field Validation based on Change Severity

[Wynand.Ferreira]

I am looking to implement the following validation at Create screen for the user:

First Selector option:

Change Type = Normal

Change Type =Emergency

Validation to be applied:

If Change Type = Normal

then

Field [Change Start Date & Time] may not be before the following Friday 11am (CAB is at this time and no normal change may be started before CAB approval is done at this time).

Field [Change End Date & Time] may not be before or equal to [Change Start Date & Time].

If Change Type = Emergency

then

Field [Change Start Date & Time] may be any date and time

Field [Change End Date & Time] may not be before or equal to [Change Start Date & Time].

The validation should present a meaningful error as well if possible to show where the issue is.  All 3 fields mentioned above is mandatory fields within the create screen of this request type.

How do I go ahead in implementing this?

Welcome to the community @Wynand.Ferreira !

is Friday 11am based on a specific timezone? and do you have any workflow extension apps which enables you to create your own custom validator by using Jira Expression? like JMWE, PowerScripts, ScriptsRunner...
