Verification Reports can help you detect if the Document Types configured for a process are valid.
Sample error text: If there are more than one Document Types assigned to a DIP Process, one of the fields in the DIP file must be a Document Type field.
This error indicates that the XML Index DIP process was configured with multiple Document Types, but no Document Types were assigned to the >>Document Type or the >>Document Type Number Default Keyword Type. To fix this error, modify the process format's configuration so that at least one Document Type is assigned to a >>Document Type or >>Document Type Number Default Keyword Type.
