The incompletion procedure determines to what extent further processing of the document is allowed and if subsequent documents can be created. If configured with no warning message, the system will indicate the sales document is incomplete and offer an option to complete missing data upon save. Incompletion procedures can be configured to (1) raise no messages, (2) raise a warning message, or (3) raise an error message. Incompletion Log ensures that all required fields in a document are populated.
