This window displays the details for the original Transaction in the top part of the window, and the details of the Detail lines for that Transaction in the lower part.

The Audit Number of the Original Transaction (in this case a Purchase Ledger Invoice), was 4.

The Detail line in this case resulted in three postings to the Nominal (a credit and two debits), all three of which will have the same Audit Number, in this case 13.

Postings from different Ledgers may give a different pattern of postings.
