If a vendor or business unit was not detected automatically when an invoice was recognized, you can select one from the database. ## Look up a vendor or business unit Click the **Find...** button on the form. The **Lookup for Vendor (Business Unit)** dialog box opens. Begin typing in the search box. Matching entries appear in the list, and all fields of the current record appear on the right side of the dialog box. Select the record with the mouse or arrow keys, and click the **Select** Select button button. The fields from the record are inserted into the group's fields on the form. If you cannot find the entry, click the **Reset Data** Reset Data button button to clear all the fields in the group. ## Add and edit vendor and business unit records This feature must be enabled by the Administrator. To process invoices, ABBYY FlexiCapture needs vendor and business unit information, so the **Vendor** and **Business unit** field groups are mandatory. Recognition begins by searching for the vendor and business unit. These fields are detected using your list of vendors and business units, which is a local copy of an external database. The local copy is synchronized with the external database periodically. If you cannot find a vendor or business unit record in the local database copy, add it manually so the fields can be found automatically on invoices. If any data changes (for example, a vendor address), update the local database copy. ### Add a record to the local database copy Click **Find...** on the data form to open the **Lookup for Vendor (Business Unit)** dialog box. Click **Add Record** Add Record button. Enter your data in the dialog box, save the changes, and close the dialog box. The record is added to the local database copy, and its fields are highlighted in green. The **Id** field on the data form shows **UNKNOWN**, which means the record currently exists only in the local database copy and is not yet stored in the external database. The invoice is assigned the **Exception** status, and all subsequent invoices from this vendor have the same status. Once the new vendor record is added to the external database, the **Id** field is populated in all subsequent invoices. ### Edit a record in the local database copy Click **Find...** on the data form to open the **Lookup for Vendor (Business Unit)** dialog box. Click **Edit Record** Edit Record button. Enter your data in the dialog box, save the changes, and close the dialog box. If you are not using a vendor database, ABBYY FlexiCapture uses neural networks for field detection, unless neural networks are disabled in the program settings.
