We have our main database on a server, there is this stored procedure; when we run it against the database, it returns wrong values.

But when I take a back up of this database and restore it on another server and run the exact same query, it returns the correct answer.

What can I do?

Is it possible that the configuration of SQL Server affects how a query returns results?

If yes where can I start looking for problem ?

Here is the stored procedure, the exact same procedure runs on both databases and both databases are identical.

Without a copy of your db (not a request) it's not possible to answer this.

Is it possible that the configuration of SQL Server affects how a query returns results?

Yes this is a possibility. For example, if your ANSI NULL settings are different between the two servers then NULL will be equal to NULL on the server has ANSI_NULL set to on OFF but not on the server where ANSI_NULL is ON. Collation is another. If one server has a case sensitive collation the "A" and "a" are not equal whereas the opposite is true using the SQL Server default. These are just a couple examples.

That said, they way to isolate the problem is to break the stored proc up into parts and try to identify where the differences are starting. In the first steps, where you assign variables, add a step to dump them into a temp table that you can summarize and compare across both servers. If there's no differences keep moving down the proc running each part until you find a difference. Often I'll comment everything out then uncomment code from top-to-bottom until I isolate the problem.

Lastly, you are using couple cursors here and don't need to. You can simplify your code by making it more set-based and therefore less verbose. It will be much easier to troubleshoot and will perform much, much better.
