- make sure you report does have a private dataenvironment
- remove any tables from the report DE
- remove alias from the fields on the report

Thanks Evan.
The report DE doesn't have tables associated
the alias was removed from the fields on the report
But when run the report, the report show me a form to select the table (I do not want that)
Sorry!!, Where can I check private dataenvironment for my report. I check properties on dataenvironment, but can not see where.
Thanks again.
