The option to display general journal line number when validating to easily visually identify error message in addition to displaying the amount and date of the voucher or voucher number, maybe helpful.

Not displaying the journal line number, the user must identify voucher, plus amount, plus date, instead of easily identifying journal line entry number.

Displaying the general ledger journal line number when validating and potentially encountering error (s), the user may visually easily identify errors by journal line number, instead of reviewing journal entry.
