• What is the cause and solution for SAP error message LMON058 - You cannot expand this object class; no objects selected for the class ?

  The SAP error message LMON058 indicates that you are trying to expand an object class in the SAP Landscape Management (LaMa) tool, but there are no objects selected for that class.
