Connection Between Other SAP Systems and
SLD
The sldreg executable is used to transfer data to the SLD for a system that is neither ABAP nor J2EE-based. When triggered by other SAP systems, the sldreg sends data in an XML format using a predefined document type definition (DTD). It uses an HTTP connection, as shown in the figure below:

For example, Search and Classification (TREX), SAPOSCOL, and so on, generate such an XML and trigger the transfer of data to SLD via sldreg.
The sldreg executable and the required libraries, which are linked dynamically, are installed with your ABAP or J2EE-based system.
