What must happen to an Invoice model before it can be used in Document Training Web?

For an Invoice model to be utilized in Document Training Web, it is essential that the model is published first. Publishing an Invoice model means that it is made available within the Mendix environment, allowing for the necessary configurations and training processes to be applied. Once a model is published, it can undergo training to recognize and process incoming documents effectively.

If the model is not published, it would not be accessible for use in the Document Training Web, thus preventing any training or document processing from taking place. This step ensures that the adjustments and configurations done in the Mendix environment are correctly recognized and utilized by the Document Training Web, which relies on published models to function correctly.

While training the model, using it immediately or sharing it with users are processes that may follow publication, they cannot occur until the prerequisite of publication has been satisfied.
