We have created a project containing Receipts document definition. Is the training in Receipts project based on variants or vendors?
The Receipt project uses variants for training, however, they are based on the company (vendor) data set. You can access it via Document Definition Editor > right click on the Receipt section > Properties... > Data Sets > Variants and fill it in connecting some external database or via a script, or manually.
To give operators an opportunity to add new vendors into the Variants dataset during verification, follow this instruction in Online Help: Using data set to improve detection
