Is it possible to implement exclusive control?

[坂下弥]

When multiple people change the same item (epic, task, etc.) at the same time in JIRA WBS,
No particular message will be displayed, and I think it will be overwritten by the content executed later.

Is it possible to apply exclusive control like one of below example to prevent the previous person's updated content from being deleted?
・If someone is updating, control to prevent others from updating (display a message, etc.)
・Display in real time so you can visually see who is updating

Welcome to the community @坂下弥 !

When it comes to seeing who has made the changes within Activity section of the ticket:

As for limiting the others from updating, you can manage this within your workflow and the Conditions where you define that users in the project role of "Administrators" (this is the example only)

[John Funk]

The Conditions in the Workflow will not keep users from updating fields - it will only control who can transition the issue to another step in the workflow.

Good mention! Properties will come in. jira.permission.edit.denied

thank you.
I made this inquiry at the request of a user, but there was a slight discrepancy in the content, so I'll ask a new question.
I will close this matter.

Hi @坂下弥  - Welcome to the Atlassian Community!

You can see some of that behavior if you are using Jira Work Management projects, but not with Jira Software projects. Not sure that will change any time soon. The other question would be why are there multiple people updating the same card at the same time? Maybe there needs to be sub-tasks created where the work can be divided out.

Hello @坂下弥-san,

Looking at your other question postings, I am guessing that this question is most likely about WBS Gantt-Chart for Jira.

WBS Gantt-Chart for Jira does not currently have exclusive control or the feature to reflect the edits of multiple users on the Gantt chart in real time.

They have been submitted as feature requests to our development team and we are looking at opportunities to work on developing them in future product updates.

We are committed to providing you with an outstanding user experience. If you have any comments or questions, please feel more than free to share with us here or through our support portal.

Kind Regards, 
Yasuhiro
