In a process of consolidated identity management system provisioning to manage access across landscapes, a request is received to provision an entity in one or more heterogeneous landscapes. The request includes one or more sub-requests. Upon determining that the one or more heterogeneous landscapes corresponding to the one or more sub-request is connected to a central IDM system, the entity in the one or more heterogeneous landscapes is provisioned via the central IDM system. The status of the one or more sub-requests is determined using a push pull mechanism at the central IDM system. Upon determining that the one or more heterogeneous landscapes corresponding to the one or more sub-requests is not connected to the central IDM system, the entity is directly provisioned in the one or more heterogeneous landscapes. The request is closed after receiving the status update from the individual one or more sub-requests.
