Entity Read Operations

Entity Read MBO operations refresh a single instance of an MBO composite graph in the SAP Mobile Server cache for Create and Update operations, and are typically used when the Create or Update operation cannot return the entire graph.

The input of the Entity Read operation is a primary key. The Entity Read operation is not called directly by a client; MBO Create and Update operations invoke it if the "Immediately update the cache" operation cache policy and the "Apply output of ENTITY READ operation" option are selected, to immediately apply the results of the Entity Read operation to the CDB.

For example, a mobile application client executes a Create operation. After the EIS to which the MBO is bound is updated, an immediate refresh of the cache for a composite object graph based on the definition of the Entity Read operation is triggered, if "Immediately update the cache" and "Apply output of ENTITY READ operation" were selected by the MBO developer for the Create operation.

The Entity Read operation uses operation arguments filled from MBO primary-key attributes to create a findByPrimaryKey Read operation.
