We have service desk tickets that get linked to product boards for development work. Is there a way for reporting to not receive duplicates when pulling information. For instance, when I pull all open tickets from the previous weeks I get the project issue and desk issue. I want to get everything at once. I know I can write a query. Just wanting to know best practices when linking product and desk tickets
When you duplicates, can you explain more and what you mean by 'getting everything at once'. For Service Desk issues, I create a filter to pull only Service Requests and display the link in my results to see the Jira Product Board linkage.
You are on the right path - you should most likely write a JQL that excludes issues with issue link being Duplicates.
And yes I would also use issue linking between JSM and JS projects.
Depending on how the issue linked issues are connected you might want to use or add other issue link types :P
