Suppose that there are items in the QAD Enterprise Applications item and product structure tables that are valid variants (configuration descriptions), but which were not created using the QAD Configurator questionnaire. These variants do not have a configuration ID in QAD Configurator and can never be selected as existing variants. Using Manual Configuration Maintenance, it is possible to create this configuration description afterward and link it to the item in QAD Enterprise Applications.

Using Manual Configuration Maintenance is a way to enable QAD Configurator to substitute existing variants in a product structure, without going through analyzing and answering all the questions on the questionnaire.
