This is the JSU for Jira Server/Data Center documentation. If you are using JSU on Jira Cloud, see our JSU Cloud documentation.
Description
The 'Clear Field Value' post function clears the value of a specified field after a transition has been completed.
Configuration
You must specify the field to be cleared, for example, Fix Version.
Precondition
If you are using preconditions with a JSU post function, you can use the following options to define how the precondition is evaluated:
Ignore precondition (default): Every precondition is ignored which means that the post function will always be performed
True: Precondition must be true to execute a post function
False: Precondition must be false to execute a post function
Learn more about JSU preconditions in Workflow Preconditions.
Issue relation
The field can be on the issue in transition(within the same issue) or a related issue, like a subtask, a linked issue, an issue within an Epic (during the transition on the Epic), or the result of a JQL query.
See Related Issues for more details on each option.
Perform As User
When choosing a user account to run a post function, the account specified must have the appropriate permissions to perform the actions of the post function, for example, creating an issue or adding a comment. You can specify a different user account that owns the necessary permissions that acts only as a technical (impersonation), with broad permissions, but not used to log in to a Jira account as an individual.
If you don't specify a user here, the transition on the related issue is performed as the same user who triggered this post function on the origin issue by default. Therefore that user must have the necessary permissions on the related issue. In some setups, that user might not have the required permissions on the related issue or even access to the project of the related issue.
In combination with the User is in Any Users condition, you can hide a transition from all users other than the 'Perform As User' user.
Position of the post function
Jira transitions include essential post functions that are executed in a specific order. When adding JSU post functions to a transition it is important to position the post function with respect to the essential post functions.
‘Create’ transition
The ‘Create' transition is an issue’s first transition and does not have a source status (only destination status - usually Open). If you add the ‘Clear Field Value’ post function to the ‘Create’ transition, you should position it before Jira’s 'Create the issue originally' post function except when clearing labels that need to be cleared after the issue has been created.
Any other transition (not ‘Create’)
Position the ‘Clear Field Value’ post function anywhere before the ‘Update change history for an issue and store the issue in the database’ post function.
Supported field types
JSU supports many different field types such as system fields and custom fields. However you should be aware, that not all field types are supported, and not in all combinations. We aim to cover the most important field types and are continuously adding and improving how different field types are supported. Some custom fields of other third-party apps might never be supported. You should always test anything you do with issue fields with JSU. You can try it with a free 30-day evaluation license.
