Configuring Systems to Connect to SLD 
Purpose
Systems that are installed in your system landscape periodically send data to the SLD. You have to configure the systems to connect to SLD and periodically send data.
Process Flow
Depending on the system, the following ways to send data to the SLD exist:
¡ An ABAP-based SLD data supplier uses an RFC connection to send data about a Web AS ABAP system to the SLD bridge by means of an SAP gateway.
The ABAP-based SLD data supplier (transaction RZ70) is available for all SAP systems as of SAP Basis release 4.0B.
¡ Some components, such as XI and the Solution Manager, use the SLD Application Programming Interface for ABAP-Based Systems to send data to the SLD.
¡ A J2EE-based SLD data supplier uses HTTP to send data about a Web AS Java system to the SLD. The SLD can forward the data to one or more other SLD servers.
The J2EE-based SLD data supplier is available for all J2EE Engines as of SAP Web AS release 6.40.
¡ Some components, such as XI, use the SLD CIM Client to send data to the SLD.
Systems that are neither ABAP nor J2EE-based use the sldreg executable to send data to the SLD.
