Prerequisites

In addition to the SAP_BPM_ODATA role, you need the necessary permissions for specific task operations. For example, a task with a custom action can only be completed by its owner. Therefore, the task needs to be claimed before this operation can be performed. To search for users, you need to have either the SAP_BPM_ODATA_SEARCH_USERS action or the SAP_BPM_ODATA_INBOX role assigned to you. To read user information of another user, you need to have either the SAP_BPM_ODATA_READ_USER_INFO action or the SAP_BPM_ODATA_INBOX role assigned to you. For more information about BPM roles and task owners, see Authorizations and Roles and Defining Task Owners.
