How to get a windowed function working in WHERE clause - sql-server

Question

I know that there are quite many threads on "Windowed functions can only appear in the select or ORDER BY clases" topic, but I have read them through and just don't seem to get any of those trick to work for me. So here I go.
My Query you can see below the line. I have highlighted the part of the Query which is "causing" me issues or problems. The thing is that I would like to get
"LocalCurrentAmount not between -1.000000 and 1.000000"
in somehow. I have tried the CTE versioon, but somehow didn't work and my declare tables and then the details view started causing problems.
Would really appreciate your help!

When using a Window function, like you said in your post, you can't use it in the WHERE clause. The common solution, therefore, is to use a CTE and reference it in the WHERE outside of it. I've used your CTE, however, without any kind of sample data this is a total guess. I've also left a lot of comments for you, and changed some other parts of the SQL, as some of the clauses you have will effect your query's performance.

It's worth noting that the above sql is completely untested. I do not have access to your server, or data, so I'm purely relying on "my eye" to note any errors.
