Data Refresh Data Flow

Data refresh occurs when enterprise information system (EIS) data updates are propagated to the SAP Mobile Server cache database (CDB).

There are two general categories by which data refresh occurs:

SAP Mobile Server pulls – pulls updates from the EIS either through SAP Mobile Server configuration or policies defined by the MBO developer.
EIS pushes – a DCN option that includes all information required for an update are pushed to SAP Mobile Server.

Data Change Notification Data Flow
Data change notifications (DCNs) refresh data when a change to the enterprise information system (EIS) occurs.
Cache Group Data Flow
A cache group policy determines the frequency and the level to which mobile business objects (MBOs) belonging to that group are refreshed.
Operation Cache Policy Data Flow
An operation cache policy provides options by which data refresh is controlled for a given MBO create, update, or delete operation.
Data Refresh Initiated by SAP Mobile Server
Configure SAP Mobile Server to "poll" the enterprise information system (EIS) at scheduled intervals to determine if data has changed. If it has, the EIS refreshes cached MBO data.
