I believe I know the answer to this but looking for confirmation.
Does the UD use the @STATION value?
FWIW - I am using SET_STATION to alter @STATION and part of that alteration is making date and time part of the Station ID; if a user loses connection (REV_LOADREC error or other) and restarts and reconnects, their previous locks are not being released or re-instated depending on how you want to look at it?
This leads me to believe that @STATION value is playing a part?
Thanks.
