SAP HCM Agent

Overview

SAP HCM agent is an agent provided by UNIFY Identity Broker for SAP HCM. It is a shared component between all UNIFY Identity Broker for SAP HCM  connectors. Using the SAP .NET Connector, this agent can perform Remote Function Call (RFC) calls against ABAP Modules. The Agent performs this task by first authenticating with a SAP Security User with permissions to access the ABAP Modules, and then invoking the methods exposed by the ABAP Modules in order to perform read and update transactions with SAP HCM. As these ABAP Modules are isolated, an SAP Security Consultant is able to restrict the functional and data access to callers.

Configuration

SAP HCM agent maintains the following configuration:



Name Description
Host The IP address or host name of the SAP server hosting the ABAP Modules and instance of SAP HCM.
System Number The SAP System Number. For more information on this value consult an SAP expert.
Client The SAP Client Number. For more information on this value consult an SAP expert.
Username This defines the SAP security user used to authenticate with SAP when contacting the ABAP Modules via RFC.
Password This defines the password of SAP security user used to authenticate with SAP when contacting the ABAP Modules via RFC

Remote Function Calls (RFC)

SAP has a method of remote method invocation called Remote Function Call (RFC). This technology has existed since v4.6c, and it forms the basis of Identity Broker’s ability to broker identity data with SAP ERP Human Capital Management.

UNIFY Solutions provides especially written ABAP modules which are invoked using RFC. Identity Broker for SAP HCM uses RFC to transfer data in bulk for both the retrieval and updating of identities.
