Nicely done with all the screenshots. I did not know you could do that with SSRS.

Hat's off to you. I don't use SSRS but this looks like a really well thought out article with the correct order of revelation and all the right screen shots.

The only thing missing is performance. Have you tried this on a, say, 100,000 node hierarchy?

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Hi

Thank you for your compliment

This will encourage me writing more article 🙂

It's good question about performance in large dataset when using recursive group

It will be nice to make some performance test

I have already developed report with about 5,000 lines with no big issues

But for more than 100,000 it will be hard for SSRS to manage this. Maybe by doing some pagination.

Perhaps combining SSRS with a little T-SQL would go a long way. Please see the following article (and its predecessor)...
