• What is the cause and solution for SAP error message /IWFND/CM_V4_RUNTIME005 - Expand/Select not supported for functions ?

  The SAP error message /IWFND/CM_V4_RUNTIME005 indicates that the Expand/Select operation is not supported for the function you are trying to access in an OData service. This typically occurs when you are trying to use the $expand or $select query options in an OData request, but the underlying function or entity does not support these operations.
