George:

Softrak provides sample "views" and "workspaces" with GridView.

If you look in the folder \Softrak\GVWIN\Views\Adagio you will see a number. For instance, you will see a View called VendorTransactions.gv. It is part of a Workspace named "VendorTransactionsAndPayments.gvs".

The latter may be the best tool. Open GV, point it at your live data and then open the workspace shown above (use File | Open Workspace). Double-click on a Vendor code (1st column) and the transaction grids will refresh to match that Vendor.

Let us know if that is what you want to see.
