Ken,
Set exclusive off
Set multilocks on

And instead of rlock() use :
do while !rlock() ...unlock...enddo.
With set reprocess to 1, and some delay in "do ... enddo" routine this works.

An easier way is to make PK value char and let it have default value of sys(2015). For multiuser you could stuff its first character with station Id.
