Validate some fields before create a task or subtask

[Matteo]

Hello,

I need to validate some custom fields, for example that the value on custom filed is not greater than a certain number and so on, before creating a task, otherwise a warning or message appears, how can I do that?

You can use validators to do this, but you will need to find an app that provides a validator for "number is larger/smaller than", the built-in ones do not have that

I know that Jira Script Utilities (JSU) is an example that does have this type of field validator. I would imagine the Jira Miscellaneous Workflow Extensions also has this ability, although I've used that plugin much less.

Tank you, i'll try with the JMWE.

Hi Matteo - Welcome to the Atlassian Community!

Unfortunately, this is not available. You might be able to use the ScriptRunner Behaviours add-on app, but I think it is very limited as to custom fields.
