Did you enter your journal entry using "Transaction" Journal Entry and then update the Transaction Journal?

If you are referring to the Daily Transaction Register, go to General Ledger > Main > Daily Transaction Register to verify all entries have been updated from other modules.

If you know the source journal number, go to Source Journal History Report to review the entry, verify the posting date is correct?

If you do a transfer from one bank code to the other, and they are pointing at the same GL account, there would be no GL transaction.
