B1_JournalTransSourceView and JDT1 regarding

Question

Dear Friends,
Can you please clarify the significance of the following two lines in the code given below? I have commented these two lines as I am getting any difference by enabling or disabling it.
--               AND (T3.[TransType] <> N'I'  OR  (T3.[TransType] = N'I'   
--               AND T3.[InstlmntID] = T0.[SourceLine] ))
Here, basically the B1_JournalTransSourceView is primary concern and it's exact behavior.
