Is there any approach to increasing the performance of below query?

Question

The below query is returning almost 800k records for period Sep-21 with all account and LOB and is taking 9+hrs to generate a report.

the code is pretty straight forward. When tried with individual queries, i.e, inline and outer query, it was taking less time (Individual), but when i join those 2 query with the condition

AND gl.gl_sl_link_table (+) =XAL.gl_sl_link_table
AND gl.gl_sl_link_id (+) =XAL.gl_sl_link_id 

this was taking time. Is there any approach to modify this query, such that overall performance is increased?
