Hi Frank,ESP has a variable ESPSADG:
You can also use the ESPSADG symbolic variable in a CA WA ESP Edition procedure to affect the simulation. This variable is set equal to 1 during SADGEN processing; otherwise, it is set to zero.
You may run simulation and check how ESPESPSADG is defined, and if it's related to the above variable. Also you can add "ECHO %ESPESPSADG" and see if it shows 1 when running SADGEN and 0 for other scenarios.Hope this helps,Lucy
