ZConsulto Academy: fix guides for SAP® Business One

Step-by-step fixes for the SAP Business One errors we see most, written by our consultants. Each guide gives the exact message, why it happens, and the steps in the desktop client and the Web Client.

Guides

Numbering series

“Failed to connect System Landscape Directory (SLD)”

Nobody can log on. What to check, in order: the Server Tools service, the network path, the SLD address and the certificate.
