Specify the duration of cache data validity by configuring SAP Mobile Server updates to mobile business object (MBO) data for a scheduled cache group.
Prerequisites
You can configure a schedule refresh for a cache only if the developer enables the cache group as "scheduled" during development. Otherwise, the Schedule tab is not configurable in the Cache Group Properties dialog.
Procedure
- In the left navigation pane, expand the folder and select the package for which you want to configure
cache settings.
- In the right administration pane, click the Cache Group tab.
- Select the cache group you want to configure and click Properties.
- In the Schedule tab of the Cache Properties dialog, set the frequency of the refresh by selecting an appropriate Schedule Repeat: hourly, daily or custom.
This property determines what other schedule properties you must configure. Each option is documented in a seperate topic which further discusses the details for each frequency type. For more details, see the corresponding topic.
