Thanks Stefan, this helps however are you able to confirm if having two independent scripts running simultaneously in the same model across shared data in the WB table could present a problem?
I'm thinking particularly of table or record locking with the risk of one or more packages failing (e.g. unable to write to the corresponding sgData table). I seem to remember we have had issues when a scheduled package is running and a user is manually processing a script at the same moment in time
