When I run a Cognos report I get an error message (QE-DEF-0157) telling me "The model or package does not exist or you are not allowed to used it because of security settings." What does this mean?

The most common reason a user will see this message is because their security settings will not allow the report they are running to retrieve the data from the data source. If you get this message, in the first instance, contact the report "Owner" to find out if there is a reason you are not able to run the report. To find out who the "Owner" of the report is, go to the "Properties" of the report (icon under "Actions" in Cognos Connection).
