This tutorial explains how to synchronise the Assignee field in Jira with task resources or a text field in Microsoft Project.
Learn how to map JIRA users to Enterprise Resources in Microsoft Project Server or Project Online and import JIRA users into the Resource Pool.
Question: How to set Assignee in Jira if the task is assigned to multiple resources?
Answer: Ceptah Bridge cannot synchronise multiple resource assignments because there is only one Assignee in Jira. There are a few ways to work around that:
Map Assignee to a text field by name, e-mail, login (Server) or Account ID (cloud) and populate this field with the value that identifies the desired Assignee for the issue.
Write a VBA macro that implements custom logic to decide which resource for a task should be the assignee and populates the above text field accordingly. That macro can be run before synchronisation using Ceptah Bridge events.
Create separate tasks for each resource in MS Project and generate sub-tasks in Jira for each of these tasks under the parent issue.
Question: Why do I get an error 'The user with the email address (full name) xxxxxx does not exist'?
Answer: Most likely, the users did not make their email addresses and/or names public in their Jira profiles, and, as result, your account does not have access to this information. Ask the users to update their profile visibility settings in Jira to resolve this issue.
Question: How to avoid errors when the Jira user names contain commas?
Answer: The errors occur because when Jira user names include commas, e.g. "Smith, John", they are treated as list separators by MS Project, so it thinks that Smith and John are two separate resources.
There are a few ways to work around this:
Map Jira users to MS Project resources using a custom resource field:

and populate the field with Jira user names. This way, the names will be treated as a single string and not split by commas.

Map Jira users to MS Project resources using e-mail or Data Center login to avoid formatting issues.
Adjust the list separator character in your Windows regional settings.
