When we use a serial number, meaning that each unit produced have only one ID associated, the system shouldn't allow to generate a production record on the same operation if the serial number has already been generated. It happens by human mistake when workers are typing the serial number. If this happens the system must send a message to the operators inserting the production indicating the SN has already been generated for that operation (the system must help the operator and work as poke-yoke). This is important to change, beside all described mentioned above, if you enter this repeated operation the system count it as (quantity) produced and therefore the operators are unable to record the reality of the shop floor.
