Summary :
This SAP Note addresses the verification and suitability of hostnames in the System Landscape Directory (SLD) context. It identifies hostname variability due to factors like multiple network adapters and DNS aliases. For SLD integration, hostnames should be consistent, lowercase, and lack network domains. Virtual or DNS alias hostnames, stable over time, are recommended for avoiding duplications in SLD. It specifies that the hostname "localhost" is unsuitable for SLD use, advising against its inclusion as a profile parameter. The SLD Data Supplier must ensure that it delivers only the virtual hostname to avoid misrepresentations in system landscapes.
