Time dependent masterdata in Query /different key Dates in one query ?

Hello experts,

i have a report requirement.

Report must show all employees, who begann in last 5 years to work, their starting salaries and their first department in the Company.

EMPLOYEE is time-dependent Infoobject.

DEPARTMANT is time.dependent attribute of Infoobject EMPLOYEE.

STARTING DATE is an attribute of Infoobject EMPLOYEE

Salaries are in an Infocube.

In Query Designer, i can select only one "Key date"

But i Need for each employee a different Key-Date (STARTING DATE)

How is it possible ? Do you have any other ideas ?

Thank you.
