After you apply hot fixes E9BB98 and E9BB99, the implicit Pass-Through facility incorrectly generates column aliases in the SQL procedure's GROUP BY clause instead of generating the corresponding column names.

This behavior causes performance problems because all rows are returned to SAS before the GROUP-BY processing is applied.
