How to make a parameter of SSRS report to select the financial dimensions???

How to make a parameter of SSRS report to select one of the financial dimensions like Business unit, Employee, Mobile, Cost center etc in Microsoft Dynamics AX 2012 R3.

This is not something simple, general idea is that you will bring the tables like [DimensionAttributeValueSetItem] / [DimensionAttributeValue] / [DimensionAttribute] for each financial dimension you want to do into the report query logic, then, bring in lookup logic into UIBuilder for the report. Once the value is selected, parm it in contract class, to hit the desired data records.
