In this case, you could try creating a new calculated measure using a tuples
Try this code:
(
[Measures].[Transitions to status issues count],
[Transition].[Closed => Closed]
)
But please make sure that you can find a transition “Closed => Closed” in “Transition dimension” when you expand “All transitions” member in a simple report.
Then you could select your new calculated measure in columns and display results by transition author.
It should return the number of issues that has sent from “Closed to Closed” in selected time period.
