First of all, debugging it's very easy. Replace EXEC(#SQLQUery) with print and then you see your actual query.
You had some sintax error ( some places where AND was missing a space in front) and also you have some interger that were treated as strings.
Try my updated procedure.

Answer 2

It seems that procedure is getting called properly but no rows are getting returned, to debug the exact problem you can write actual hardcoded query returning 1 or more records instead of dynamic query.
So after doing that there are two possibilities
procedure call via edmx returns data, that means parameter values are causing some problem.
Any Data is not returned.
To solve any of the problem you need to check corresponding sql query which is getting generated while calling SP via Enitity Framework.
