When i deploy to production server the rpt is blank

[Lester]

Hello.

I defined a cyrstal XI rpt format in my dev pc and pass the database,
user, server and pwd to crexport and the report works fine.

but when i deploy to the production server, and pass new database,
user, server and pwd the report is generated blank.

the rpt is based in a sql stored procedure, if i run the call to the
sp from the sql management console, it returns data.

Thanks in advance for any help.
