Understand first operation production

A work order routing contains at least one designated first job. If you do not require linear flow for the work order, production can start through the work order at any job that uses that item.

When an item is soft pegged, MES Operator checks the local inventory for available serial numbers. If no serial numbers are found, MES Operator checks for the serial numbers that are assigned to a work order and are not in process in the Lot table. The Add Production dialog box lists all the serial numbers in local inventory and all the serial numbers in the assigned Lot table that are not started.

If an operator has permission to create a new serial number and no serial number is assigned to a work order, an operator can add serial numbers and assign them to a work order.
