You are performing an uncorrelated subquery in your NOT EXISTS() condition. It always returns exactly one row, therefore the NOT EXISTS condition is never satisfied, and your query returns zero rows. Oracle has a rowset difference operator, MINUS, that should do what you wanted:
WHERE NOT EXISTS (SELECT 1 FROM tmp_rtmr_accounts tra WHERE stg.gl_account_code||' 000000' = tra.account_code_n106) OR NOT EXISTS (SELECT account_code_n106,product_code FROM tmp_rtmr_accounts tra WHERE stg.gl_account_code||' 000000' = tra.account_code_n106 and EXISTS (SELECT 1 FROM tmp_rtmr_products trp WHERE tra.product_code = trp.product_code ))
