We are finding that users DistIDs have been reverting to a default of their TSO userid.
We switch to the desired DistID but later it is changed back to their default TSO userid.
Release : 14.0
Component : CA View
According to the documentation on the View SARBCH /DEFUSER update function, if you omit the DISTID=... field in an update, DISTID=UserID will be used.
As the client has been using a batch SARBCH function, using the /DEFUSER function, it is likely that the DISTID=... field was omitted, assigning UserID to the DISTID field.
