Auditors must gather evidence, and obtain documentation around identified risks. A risk in the purchasing process is that a purchase is made from an unauthorized vendor. To gather evidence around this risk, we first want to open and join the two data sets (Accounts_Payable and Vendors) for Roger Company to begin the process for identifying the unauthorized vendors. Once the file is open, join the databases. With the Accounts_Payable file open, on the Analysis tab, in the Relate group, select Join to open the Join Databases window. Select Vendors as your Secondary database. Join both databases by vendor number in the Match menu (refer to Section 4 of the tutorial for additional help. Hint: AP Vendor Number must both be the same field format, i. e., either both numeric or both character). Choose to retain all records in both files.
