Can a field be set to mandatory based on the value entered for another field?

[Bianca Sarmiento]

Hi, can a field be set to mandatory based on the value entered for another field without the use of a plug-in?

For example, if 'Cross Team Issue' field is selected "Yes" then make 'Delivery Date' field mandatory, otherwise leave as optional.

Not without a plug-in, no.

Only a few plug-ins (apps) can help with that, such as JMWE (our app) or ScriptRunner.

Thanks David. What is the best way to do this in JMWE?

[David Fischer]

You can use the "Field Required (JMWE app)" Validator and use "conditional validation" to activate the validator based on the value entered for another field, for example:

!!issue.priority && issue.priority.name == "Blocker"

would make the selected field mandatory only if the issue's priority is "Blocker"

The Jira expressions editor and its help system will help you write the conditional validation script.
