How to expand the vertical data groups one by one?

[prabha_friend]

I can able to show the different levels on the outline through but not the vertical data groups.How to do it? I tried expanding the "+" sign one by one using record macro but no code was trapped.I want to individually expand, read data and close the vertical data groups. File attached on the trackback link. No ways to attach file here?

I am just looking for a code to do the "Show Detail" and "Hide Detail" programmatically. Possible?

rows(rownum).showdetail = true solves my purpose. Any other effective method than this?
