Let’s see step by step how an issue is created in Atlassian JIRA.
Click Create at the top of the screen to open the Create Issue dialog box.
Select the relevant Project and Issue Type in the Create Issue dialog box.
Type a Summary for the issue and complete any appropriate fields (required fields are marked by an asterisk)
Note: Make sure you check they’re all correct before creating the next issue.
When you are satisfied with the content of your issue, click the Create button.
