I want to use CiviCRM in a new project right now. In this project, it is necessary to assume an activity. So before creating an event for xxx individual registration, this xxx individual transaction must undertake. No one else who has taken over the registration and who has the authority to open a record in Joomla / CiviCRM on this individual until the transaction (new activity) completes.
Here's the story. Only joomla users can access CRM. When a person is interviewed, a Phone Call activity is created for this. If there is a need for additional support, the shared e-mail address of the related team is added to the Assigned section. Since there is more than one person from the common e-mail address, more than one person can make transactions at the same time. I want to prevent anyone else from taking action on this record by doing something like (assume) after viewing the CiviCRM Record in this mail.
If this is possible, I would like to know how to do this, or if there is an add-on created before.
