Thank you Fazila,
Before I accept the answer, have one question on velocity. Suppose I manage multiple scrum teams, how do I track the velocity? I need a consolidated velocity chart. Do you have anything apart from the enterprise velocity chart? Thanks in advance.
The chart will pull based on the scope set by the board's filter.
So if you have multiple teams working on the same sprint in they team specific board (where you can look at team specific velocity), you can also have a consolidated board including the tickets of all the teams where you can check on the consolidated velocity of the teams
@Sundara Rao Damaraju , aggregate function like this is not built-in in JIRA.
For this specific requirement, you could look at the Velocity chart https://confluence.atlassian.com/jirasoftwareserver/velocity-chart-938845700.html
