Field help (MACCONNUM) 

This column is used to define the management of the serial number by one or several service contracts. Selecting a service contract in this grid automatically enters the list of the contract product coverages. Warning: Associating a service contract with a base record is used to only carry out the creation of product coverages of type Serial number (Base). The coverages of type Product reference can only be carried out within the framework of the "Covered installed base" function of the service contracts. This table also represents a special location to carry out the creation of Warranty contracts.
