SYNCIGNORE is used to suppress a property from being synchronized. If true the property's value will not be added to a sync set even if the value has changed. The property will be ignored during sync set import as well. The default for this value is false (0). It is important to note that if the property is constrained by a REQUIRED (NOTNULL) constraint then it will be impossible to create new objects on another system using synchronization unless extraordinary measures are employed.
