How to open and test Input Form from EPM Excel

Hi All,

I am new to BPC and working on custom logic BADI ( BPC 10 NW) . Now I have written a code and I want to test it through EPM excel. BPC consultants have already developed some input forms for PLAN model. Can anyone suggest me some links or any knowledge which can guide me how to open input form and how to test it ?

Thanks,

Niki.
