Scheduled Reports Ignoring Parameters

HI

I've set up a report on VSM 9.1.2 to display change requests for a specific list of services. It works perfectly when run manually, however when scheduled to run automatically the report generated displays change requests for all services.

It looks like the report scheduler is ignoring my list of specific services, which I've listed under the "view custom sql" section on the Params tab of the report editor.

Has anyone come across this before and do you have any suggested solutions?

Thanks

Mick
