When we create a new login in MAI, it always takes the same fixed value "APPL1" instead of taking the value of APPLNEW, which was informed by the user. This problem started to occur after recycling TASK, but there was no change in MAI or in CICS, which passes the DEFLOGON parameters.
The customer had APPL1 in the Mai Session Default.
Ensure the MAI Session Defaults the values needed.
You can check it using /ACADMIN.D shortcut.
When changes are made to the option there will be a message written to the activity log.
In your activity log ($log or /log shortcut) you should see the following message -
09.20.31 $MASD01E USER1 updated default session panel
