When you submit a receipt, invoice or other piece of financial paperwork, Dext Prepare will analyse the current document and previous documents to assign an appropriate category.
When Autocategorization is on, the tool will use machine learning to extract a category based on the way you previously categorised similar items in your account. If there is a supplier rule in place then we will only suggest a category.
You can turn ON this autocategorization by navigating to the System Settings page under the My Profile menu and turning the toggle to ON.
To keep the codes applied for known suppliers you need to keep the "Obey supplier rules" toggle on (it appears when you turn off the "Autocategorization").
