New analysis period must not exceed maximum period limit

Hi,

I am getting error while modifying Analysis period and Hierarchy area using TCODE "KS02".

Error is - New analysis period must not exceed maximum period limit

Diagnosis:

You selected an analysis period extending beyond the period for which the objects was defined. This is not allowed in the change or display functions.

Procedure:

Use an analysis period within the period for which the object has been defined.

you can derive this period from the suggested "From/To" values in this screen.

Could any one help me in resolving this issues?
