When finish success a report, not need open result page. other improve is at error, only show message box, not show this page wdyt?

As explained above this is expected behavior, the button message was fixed in another ticket.

The message "Do you want to start the process?" appears when the report doesn't have a description, so is easy to solve completing Description in dictionary.

IMHO I think is good to have the feedback that the report was finished there, maybe we could exploit that space to put some information - time elapsed - number of rows

What I think is wrong is the label of the "Cancel" button, the button must be called "Cancel" on the parameters window, but after finished the report must be called something like "Close".
On the same line the title "Do you want to start the process?" there is wrong.

yes. but i mean not need switch to this page (page has parameter button).
stay user at parameter screen. because user can immediate run other report.

Hiep, the Parameter button there allows the user to run again the report easily with same parameters or allowing to change.
