I have similar problem using sql server 2005. Error message is attached.
I have a report that has a stored procedure for a data source. It requires a parameter. It runs fine in logicity desktop. It doesn't work right in rrd file though. The rrd solution works if I select view and don't specify a login. If I specify a login I get an error. Also if i select print or save, I get the same error. When selecting print/save, i get the error regardless of whether the login is specified in rrd. I have pro version and need to make a print rrd using command line parameter. Any suggestions?
