Infoview Error - Unable to retrieve Object. Out of memory.

I have created a new Crystal report which uses a Command object to pull information from a DB2 database via ODBC.

The report works fine through the the Crystal Reports application, so I have gone and added it to the BusinessObjects server using the Central Management Console web-app. However when I try and open the report in Infoview I get the aforementioned error.

Does anyone know if there is some configuration setting I need to change on the BO server so my report will run through Infoview? I feel I should mention my report runs very quickly indeed when I refresh it within the Crystal Reports app, which is running on the same server as the BO server.

Many thanks

John
