Hi @Kunal_Kumar,
If you are looking for only one particular Board sprints, you can hardcode this within the last 6 sprint calculation. For example:
Aggregate(
Tail(Order(
Filter(ChildrenSet([Sprint].[BOARD_NAME]),
[Sprint].CurrentHierarchyMember.getBoolean('Closed') AND
NOT IsEmpty([Sprint].CurrentHierarchyMember.get('Complete date'))),
[Sprint].CurrentHierarchyMember.get('Start date'),
BASC
), 6)
)
If you would like to return only the last six sprints from any board, you can look at creating a new hierarchy in the Sprint dimension by importing an additional property to Sprint - Board name only to the last six closed sprints. Please see a similar example here Restrict sprint within board - #2 by lauma.cirule.
