What exactly is wrong with the results? Can you make the report include the gl_date so that you can see exactly what is being included?
The only way to troubleshoot this is to go back to basics. You have to be 100% certain that the parameter and calculations for the dates are working. You have granted execute permission over the function to your EUL owner - yes? What I did was create the function in a package owned by EUL_US then I had no issue with grants or permissions.
Also, gl_date is a DATE and not a string right? I ask because if it is not a date but a string then some dates might be left out.
Assuming you are 100% certain of the building blocks you should start by including only the gl_date and primary key from the table you are using. Once you are sure you are getting the right data you can start to add in more fields.
I do notice you are using E-Business Suite objects. I copied the code into my system where I am not using leasing. So I commented out the references to the 3 PN tables. I got 150 rows of data when I queried using the parameter and again when I hard coded the BETWEEN for the gl_date. You do have to make sure that your EUL owner has been granted SELECT right from all the tables and views used in your code and, if you intend to share this code with someone else, you will also need to have GRANT rights.
Try your code in a SQL tool such as TOAD and see what happens. Are you absolutely sure that every one of your transactions has an entry in the PN tables? This might be why you are not getting the results you expect. You could try, as I did, to comment those lines out and then see what happens.
Hope this has given you enough to solve your issue

PS. It would be nice to know your name. You haven't used it once in your thread.
