QTP Framework to automate Cognos Reports Testing

I am in the process of automating a testing/ comparing of 2 cognos report outputs using QTP (v11). In the current solution, due to the different data sets, I had to hard code QTP variables to compare 2 static reports.

Is there a generic solutions/approach that any of you have used to Automate reports testing in general and Cognos reports in particular.

If interested I can share the current solution in place. But I am looking for a more generic approach, kindly help if you have any idea
