BEx variables in Dashboard

Hi,

Background:

I would like to execute the query on dashboard based on the BEx Variables. I am using Company Code and Fiscal Period.

Problem:

I have noticed that we can only select the "TOP" variable ONLY to pass the variable to BEx Query from Dashboard selection. I have 02 Combo Box where the user will input the Company Code and Fiscal Period which i want to pass to BEx to execute the report.

Also the User Exit i maintain in BEx Query based on input selection are not working in Dashboard. They are working fine in Bex reports.

Problem:

1. Is it possible to use 02 BEx variables in Dashbaord ?

2. Do USER EXIT written on KF in BEx work in Dashboard ?

Thanks
