Default field values based on Issue type selection

[Salvi]

We have a requirement to set different default values for different issue types in same project.

For Example:

If Issue Type "A" is selected Custom field "Test" option should be populated with "False" automatically on create screen and if Issue Type "B" is selected Custom field "Test" option should be populated with "False" automatically on create screen within same project.

Is there any way to do this?

you can use the addon automation for jira with the trigger on issue creation, as example.

or some other script addons

Thanks Alex.

Is there a way do it via workflow post function script or using a script runner tool?

we can do that via automation based on the issue type we can fix a value in the custom field
