With the 'CAT Database' field on the General tab you can link to a BookCAT, CATraxx, CATVids, SoftCAT or StampCAT database. The total price/value is automatically fetched from this database when you open the AssetCAT database, and the Cost and Value fields are automatically updated.
To link to a database, either click the ... button to open the 'Select Database File' window, or drag the database file from Windows Explorer and drop it on this field.
