Select Partition by Requester and Device Identity to partition mobile business object (MBO) data by a requester’s identity (user id plus device id). This option ensures that data loaded into the SAP Mobile Server cache (CDB) for client defined partitions using an On demand cache policy is accessible only by that requestor.
The requestor identity is derived from the device id and the user from which a request originates, meaning that two users on the same device have different requestor identities, and the same user on different devices has a different requestor identity for each device.
