This is the documentation of JSU for Jira Cloud. If you are using JSU on Jira Server or on Jira Data Center, you can find the documentation here.
The 'Copy Value From Other Field' post-function copies the value of one field to another field. You can configure any number of source / destination field pairs. In addition to copying values from fields, this post-function can also copy from/to comments.
The copy operation will be performed either within the very same issue or to / from some related issue.
You must specify the relation between the source and destination issues for the field to copy. Then you can add any number of field pairs to perform the copy operation.
There are several ways in which preconditions can be evaluated in the context of a post function:
- True (Precondition must be true to execute a post function)
- False (Precondition must be false to execute a post function)
You can find more generic description of precondition here
Several of JSU's workflow modules provide the option the define the scope of the module on some related issues.
For example instead of copying a field within an issue during a post function, you might choose to copy it to a sub-task.
Types of Issue Relations
Related issue will be found by one of the following Jira concepts:
- Issue Link
You can define the link type to define which issues exactly will be affected by the operation.
If link type is ANY, the operation will be performed on any linked issues.
- Parent / Sub-Task
The related issue is either parent or sub-task of each other.
- Epic / Issue in Epic
This is only applicable, if you have Jira Software installed.
The other issue is either the epic related by an epic link, or it is part of an epic.
A JQL query will be executed to find the issues, which will be affected by the post function. You can use some placeholders in the JQL query, which will be replaced with current field values of the issue in transition. For writing the JQL query please follow the instructions on JQL Reference .
Also see our JQL Use Cases for some examples.
Issue in Transition
We use the term 'Issue in Transition' when we refer to the issue for which a workflow condition is checked, for which a workflow validator is examined, or for which a workflow post function is performed.
Or in other words that issue, which triggered a workflow condition / validator / post function to be executed.
Source and Destination
For example the Copy Value From Other Field Post-Function allows you to define the issue in transition as the source or destination of the copy operations, while you define the other end with an issue relation.
The field value will then be read from the source issue and be written to the destination issue.
Other workflow modules do not have source and destination. So you just define the issue relation, which will apply for that workflow module.
For example Create a Linked Issue Post-Function will just create a new issue and then connect it with some Issue Relation to the issue in transition.
Please use some common sense what can and what cannot work.
- Copy Value From Other Field Post-Function there should be only 1 source issue. Otherwise it is not clear from which the value will be read. (The current implementation will just pick one of them and ignore the rest. Which one is not defined - sort of random.)
- If you use Create a Linked Issue Post-Function to create a new sub-task, you must also configure this post function to create the new issue as an issue type of a sub-task and make sure the target project is the same as the one of the issue in transition.
We try to perform whatever is possible. In case of problems, the workflow module will still run through, but write a message into the log file. See Troubleshooting how to turn on the full logging for JSU. It might be a good idea to do this while you test any new workflow configuration to make sure you're not missing any thing.
Perform As User
If you don't specify anything here, the transition on the related will be performed with the same user who triggered this post function on the origin issue. Thus, that user must have the necessary permissions on the related issue.
However, in some restrictive setup, that user might not be allowed to do so on the related issue. He might not even see the project of the related issue!
With 'Perform As User', you can specify a different user account who has been granted the necessary permissions. Usually this user account is assumed to be only technical (impersonation), with broad permissions, and not used to log into Jira by any coworkers.
In combination with the Permission Condition in native Jira, or the User Is In Any Users Condition from JSU, you can hide a transition from all users that do not have the permission to execute it.
You can copy the value form some source field to some destination field. Click the + Button to add additional field pairs to your configuration.
Keep in mind that not all conversions from source to destination field are supported, nor feasible. We can only ensure, that it will work if source and destination fields are of the same field type, or the destination field is a text field. (Still, some additional combinations of different field types might work as well - although not 'officially' supported.)
Overwrite / Append / Prepend
For text fields and some field that can take multiple values (like checkboxes) you can choose to overwrite, append or prepend the new value to any existing value. In the case of text field, you can also choose a separator that will be put between the values (not shown in the screen shot above).
Create version if necessary
Imagine your origin issue has a version, that you want to copy to the linked issue.
If the destination field is 'Fix Version/s', 'Affects Version/s' or some custom field of type 'Version Picker', you can choose that a new version will be created in the target project, if does not yet exist. If you don't choose this option and that version does not yet exist, the user will get an error message and the transition will complete.
However be aware, that a user needs the 'Administer Projects' permission to be able to create a new version.
Create component if necessary
Imagine your origin issue has a component, that you want to copy to the linked issue.
If the destination field is 'Components', you can choose that a new component will be created in the target project, if does not yet exist. If you don't choose this option and that component does not yet exist, the user will get an error message and the transition will complete.
However be aware, that a user needs the 'Administer Projects' permission to be able to create a new component.
As source you have some additional options:
- *** empty ***
The destination field will be cleared.
- *** last comment ***
The last comment from the source issue will be copied.
In some cases that might be the comment from the transition screen, which the user just entered while performing the current transition.
As destination you have also special options:
- *** new comment ***
A new comment will be created with the copied value. When you choose to 'overwrite' to new comment, a new comment is created, enabling you to add multiple comments in one post function.
Copy Description to New Comment, overwrite → creates a new comment with the description
Copy Summary to New Comment, append with separator ", " → appends the summary to the previously created comment, so the comment will look like <Description>, <Summary>
Copy Assignee to New Comment, overwrite → creates a new comment
This configuration will result in two comments being created, one with the description and summary, and one with the assignee.
Also see the note about supported field types further down.
There is a fundamental difference between Jira Server/Data Center and Jira Cloud: In Jira Cloud post functions of apps are executed asynchronous
as a 'background job'
- This means a post function will be executed after the transition has completed on Jira Cloud.
- There is no guaranteed order in which several post functions are performed. They might be executed in a different order from the one you had set them up in Jira's workflow configuration. So you cannot rely on any result of a 'previous' post function. The order by which the post functions are executed might be different every time the transition is performed.
- When a post function has a problem (due to misconfiguration or the current data of a Jira issue), the transition (and all other post functions) will be performed nevertheless.
- The result of a post function might not be visible immediately in the browser.
- There are no error messages displayed to the user.
A workflow is configured so that the 'Resolve' transition has the 'Copy Value From Other Field' post-function. The function is configured to copy the value of the 'Assignee' field to the 'TextField' field. If a user resolves an issue on this workflow, the value of the 'Assignee' field will be copied to the 'TextField' field after the issue is resolved.
Supported Field Types
In its different modules (especially those for workflows), the JSU app supports many different field types. System fields, as well as custom fields.
However you should be aware, that not all field types or all combinations are supported. We think we cover the most important field types and are still continuously adding and improving which, and how different field types are supported. But the one you need might not work (yet).
We recommend that you test JSU with fields to see if it is compatible with your system. Our evaluation license gives you 30 days free trial.
