Underlying data

Hi All,

 1.In my report export underlying data in excel format is working. But it excluding some column in my table. That columns not a measure, it are direct column in table. why this excluding happen? What logic behind in export underlying data in excel format?

2. Underlying data columns are different from one page to another in same report

Ex: My report contains (A,B,C,D,E,F,G,H) column. 

Page No.    column in underlying data

1                   A,B,D,E,F

2                   A,B,D,E,F

3                   A,D,E,F,G

see here 1,2,3 pages in same report. But export data is giving different columns in in page. Why this difference ? (missing fields are not measure. It is a column) Report and page level only filter data not a  column. correct?

3.

I am getting this error in some visuals. In this visual i am using only two columns and one measure.

then why underlying data is disabled and asking aggregate?
