Join the Files.
The next step in the confirmation process is to join the Classified Invoices file and the Customer file (illustrated in Table 9.5 with sample data) to produce another new file called Accounts Receivable, which is presented in Table 9.6. Recall that when using ACL’s Join feature both files must be ordered on the same key. This requires first sorting the Classified Invoices file by Customer Number to place it in the same sequence as the Customer master file. As noted previously, the Join feature allows the auditor to select only relevant fields from each of the input files when creating the new file. In this example, Credit Limit, which is not needed for preparing the confirmations, has been dropped from the new Accounts Receivable file structure.
