It is part of the Easy NodeAccess (ENA) framework and gives the possibility to work with ENA outside of BOPF (in UI handlers for example) that's why it is classified as external accessor to BOPF Business Object (BO) node structure.

Do not use the constructor directly but the static factory method cl_ehfnd_ena_service_mngr=>instancev2 to get reference of the class.

The methods get_root, get_root_single, get_node and get_node_single give different ways to access the BO node structure. all of them require to have the key/keys of the node's instances you want to access.

The class holds both BOPF sevice and transaction manager instances and provide access to most of thier method.

Such methods are: save(transaction mngr), execute_action(service mngr), check_consistency(service manager) and etc
