Before to go into the detail of your question (or what I understand of it) let's fix a detail of "wording" :

What Christian was pointing out is that you call "report" a thing done in BI Publisher, while if you do that thing in OBI Answers (using a subject area etc.) the name is "analysis".

So when you say it's an analysis but then you call it report, it's confusing as there is a doubt about what tool / technology you are really using.

It's all about wording, things have a name and it's easier if we all stick to the same wording.

(You maybe now see better why saying "both analysis are it's own report" is quite ... fun )

Now, back to your question ...

You have 2 analysis (and not reports), one gives you employee, job code and grade, the other one gives you job code and grade.

What I understand is that you want a way to compare the couple job code - grade between these two analysis, is that right?

And if the couple job code - grade isn't the same in the 2 analysis you would like to see something (a color, an icon or any other visual thing) in the analysis with just the job code and grade showing you which couple job code - grade mismatch.

Right?
