Problem

How to trace this query to know the reason of why it return null records .

query below work in database and give me results but not give me any result in another database

How to debug or trace it to know why it not give me any result .

this can be easy if you know how and i agree with Nitin.
so what i generally do is

replace line 1 to 54 with

SELECT TrxInvH.*

In SSMS copy the query and....
Steps ...
--Run the query (F5), no results go to next line
--Comment line 74 from the WHERE clause
--Run the query (F5), no results go to next line Else line 74 is causing the issue
--Comment line 72 LEFT POUTET JOIN
--Run the query (F5), no results go to next line Else line 72 is causing the issue
.
.
.

Comment out each JOIN one by one and then press F5 in SSMS you will finally get some results and that point you can say that you have found the issue , keep that line commented and uncomment the ones that you havd commented before, may a combination of 2 JOIN might be causing the issue, anyways i assue you get the idea

From a data/quey design perspective your query is tooooooo big and long you will have to break it, and i dont see an optimized query

--I see over 11 joins and 6 of them are Left joins
-- too many CASE clause in the SELECT statment
-- I see 1 = 1 in the where clause twice, not sure why ,, i use 1=1 when i am doing some tests or POC, not in production

and lots more
Good luck

No expertise is needed to say that it is indeed a data issue, assuming it is working in another database as you mention it.

There is no easy way to determine where it is going wrong, considering the way it is written. Not a very good way, I must add. If it is a Microsoft SQL Server, I never understood why some developers insist on returning everything in a single select statement. Anyway.

I suggest you start with investigating INNER JOIN data because that's the one which limits the return. And also keep on commenting WHERE clause and you will probably know too.
