Here is a query that will get the results you're looking for. I don't have your data model, but this works with a basic cube I created. Hope this helps.

SELECT

{} ON columns,

NONEMPTY(GENERATE([DimEmployee].[Employee ID].[Employee ID].Members,

TAIL(NONEMPTY({[DimEmployee].[Employee ID].CURRENTMEMBER *

[Start Date].[Date NK].[Date NK]}), 1))

* [End Date].[Date NK].[Date NK]

* [DimDepartment].[Department Name].[Department Name])

ON rows

FROM [TestCube]

Hi

Thank you for your reply and the code. It worked but it gives out duplicates.

It will be very helpful, if you could help me in getting this as calcuated member.

You have a tie on the Start Date. The Tail function is pulling a list of EmployeeID and the latest start date. Then it's joining to the rest of the attributes in the query. To remove duplicates, decide on the tie-breaker and move that inside of the Tail function.

This is more of a set than a member. To make it a member, you may need a flag to identify the latest or 'active' records. I don't know your data model but it seems like this would be on the department dimension.
