Enabling the ability to refresh any changes to the lookup or system data You can enable refresh of any data changes rather than having to refresh the complete set of lookup or system data. About this task To enable the ability to refresh any changes to the lookup or system data, you specify a value for each of the following global properties: Lookup.data.delta.support By default, this property is set to true, which enables refresh of only the changes to the lookup data. Specify false to disable this function. Lookup.data.delta.autorefresh By default, this property is set to true, which enables automatic refresh of only the changes to the lookup data. Specify false to disable this function. Lookup.data.delta.autorefresh.numbers.retry By default this property is set to 3. If the default value is used, the notification to refresh the data is sent three times. After three times, refresh is disabled until the next session.
