Online learning for line items is enabled by default. This means that no configuration is required to enable online learning.

However, training documents are not collected automatically like they are when a change is made to one of the trainable header fields. Instead, if a user wants to ensure that a change that they make to the line items that is trained, the user has to press the Mark for Online Learning  toolbar setting in the Validation activity. When a document is added to the training documents, it is for that specific vendor only.

Kofax AP Agility knows what vendors have training documents for line items. For these vendors, the results from the trainable locator are given priority over the default generic extraction results. The next time an invoice from that vendor is processed, the existing training data is usually used and the extraction results should improve.

Kofax AP Agility may still decide to use the generic extraction results if the results from the trainable locator are not as good as the generic extraction. This decision is based on a cross-check against header amounts.

Invoices from other vendors using the same layout do not use online leaning unless there are training documents for those vendors.
