wdisp/HTTPS/dest_logon_group is a SAP Parameter attribute which is used to control HTTPS ROUTER protocol: logon group for SSL-End-To-End requests information. This is available within R/3 SAP systems depending on the version and release level.
Below is the standard documentation available and a few details of the attributes values .
This parameter determines the logon group for load balancing requests at
the SAP Web Dispatcher if HTTPS is used. If a logon group is defined,
the requests are passed only to the servers in this group. If no group
is defined, the requests can be passed to all of the servers in the
system.
