Well, you may want to look at the activity for one specific account, in detail, before you try to get involved in summarizing/grouping the detail. That way you will begin to understand what the grouping function in the SQL statement is going to do to you. You do not say what is wrong with your query, but I am assuming that your numbers for the Opening Balance and the Closing Balance are too high. Would that be a correct assumption? The problem, as I see it, is that you are joining the gl lines detail to the gl balances table. That means every record (row) in the join for that account for the desired period is going to have the beginning balance dr and cr columns. So if you sum up that column, you are going to sum up the beginning balances multiple times. What you need to do is first summarize your detail activity by the date, journal source, and journal category, and the debits and credits sums, for the period in question, and store that result, Then do a second query that joins that result set to the gl_balances table. Also not sure what null values are doing to you, if you have them in the debit and credit fields. You may have to convert the null values to a 0 as part of this whole process. Or do this via a custom program. Or if you have a data warehouse, you might want to see if you can handle this in the data warehouse. So some options to thiink about.
