(After a long gap, a short post)

When running a  (Saved with default answers) Ad hoc report that has been re-prompted, the metrics on the resulting report will be displayed in alphabetical order rather than in the order they were selected. 

A possible workaround to this issue is to click and highlight one of the selected metrics , then re-execute the report.

As usual, we are touch base with MicroStrategy (its known issue in 9x, please contact MicroStrategy Tech Support 😛 )
