Thank you for the quick response and solution to my issue. I was able to get the Altiris 6.0 report to work in the 7.5 NS. Since I still have a 6.0 NS up and running I was able to Clone the report and modify the SQL for what the NS 7.5 table is now using.
In 6.0 the INV_Audit table uses a Column called InventoryDate which is what the report is using for the N Days variable.
In 7.5 the Inv_Audit table, the Column has been renamed to AuditDate. I modified the report in the NS 6.0 and then Export/Import into the NS 7.5. It is still a legacy report, but it does work now. Some day I will rewrite it for NS 7.x.
Thanks for your input on this.
