In my model, there is a combiner named " Ligne Lot Panaché" which needs 4 references in order to produce a new reference.
But there is a contraint on the combiner :
If the sum of the 4 references inside the system is < 1000
then the combiner is stopped all the week
The 4 references are stocked inside the racks CA , DA and DB.
The sum needs to delete all the references that are used for the process .
If you have an idea to contraint the combiner !simu.fsm
