Hi @Tamil,
You could use a similar approach as described in this post: How to list all assignees of an issue - #2 by zane.baranovska. I adopted the formula to show all assignees during the selected period for issues that had assignee changes:
Here is the formula:
Generate(
--go through all Assignee users
Filter(
[Assignee].[User].Members,
--check wheather user was assignee of the issue during selected period
NOT IsEmpty([Measures].[Issues history]) ),
--get assignee names separated by comma
[Assignee].CurrentMember.Name,
","
)
