Outline Required Field Resolution For Free

Resolution is a system Field and it's always mandatory. You cannot make it optional from Configuration scheme. You need to remove it from create/edit screen and try creating a task. Try removing it and create a new task.

This work around worked for me. Remove the Resolution field from all views but the Closed screen. Remove the default value for the Resolution field. Set a Validator up so that the Resolution field must be changed when transitioning to Closed.

Click on the gear icon then Setup > Object Manager. Choose the object > Fields & Relationships. Select the custom field that you will make required. Click on Edit and under General Options select Required. Click on Save.

Resolution is a special field in JIRA. It has an initial value of 'Unresolved', which means the field is NULL in the database. It is ALWAYS required when it appears on the screen. ONLY display it on the screen during a transition to the status where you want it set.

As the Resolution Field is a Required Field, if it is added to a "Default" Screen, newly created or edited issues will be in a Resolved state as the field would be populated by the Default Resolution Value.

Solution Go to the project settings > Workflow; Edit the desired workflow; Find the transition that will reopen the issue and click on it; Navigate to the pop-up and click on Post Functions, then click Add post Function; Add the Clear Field Value event as a post function; Select the Resolution field and click add;

The "Resolution" field is an important feature in Jira. It specifies the reason an issue is closed and removes the need of having multiple statuses with the purpose of stating why the issue is closed, thus capturing important data for your team while reducing the time you have to manage your workflow.
