As in the previous example, the two files being joined need to be ordered on a common
key, which, again, is PO Number. Since the Disbursement Voucher file was previously
sorted on this key, that sorted output file can be used for this test also. Therefore,
only the Receiving Report file needs to be reorganized. The next step is to join the two files
to create a combined output file. This time, however, the output option is different from
the previous example. The relevant option in this case is to create an output file that consists
only of unmatched records from the primary file. Remember, the auditor is attempting
through this test to identify receiving report records that have not been recorded as
liabilities. The primary file in this instance is the Receiving Report file, and the Disbursement Voucher file is the secondary file. In choosing this option, all the inventory receipts that were correctly recorded as liabilities will be ignored by the Join process. Only the unmatched receiving report records will be contained in the new output file. The structure of the file is the same as the Receiving Report file in Table 10.5. If the output file contains any records, the auditor needs to review this information with management to determine if the
appropriate adjustments were made to the accounts payable balance.
