Work Orders

A work order represents a request for some quantity of an item to be produced. A work order is uniquely identified by its ID number. Once completed, a work order is not intended to be executed again.

For line management, work orders can be created and assigned to lines in MES Web Portal. Work orders can also be submitted to MES from an external system, such as a manufacturing resource planning (MRP) or enterprise resource planning (ERP) system, or created in MES Client. The work orders are assigned to specific production lines.

To be executed, the work order must comprise a set of jobs that represent the complete set of operations required to manufacture that product from ingredients or components. These ingredients or components may have been purchased or manufactured as the result of a previous work order. Creating a work order in MES Web Portal and assigning it to a line also creates the necessary jobs for all entities associated with the line. Unlike work orders created using MES Client and worked using MES Operator, there is no correlation to a process and therefore no concept of a bill of material in MES Web Portal. There is the produced item of the work order and the quantities (starting and required).
