Assembly orders

Assembly orders are created for product variants whose planned offline date falls in the assembly order time fence of the roll-off line. The assembly orders are created by Assembly Planning, but are stored and executed in Assembly Control. In a multicompany situation, assembly orders are created for each company. Assembly orders can only be created for assembly lines that are actualized, which means that the lines are released for use in the production process.

Assembly order statuses

An assembly order can have one of the following statuses:

  • Planned
  • Sequenced
  • In Progress
  • To be Completed
  • Completed
  • Closed
  • Canceled
Assembly order progress
  • An assembly order has the status Planned when it is initially generated by Generate Assembly Orders (tiapl3201m000) session. When this happens, line-station orders, line-station variants and exchangable configurations are generated. The line station orders are generated both for the main line and the supplying lines of the same company. You must have already defined the assembly line structure (segments and line stations).
  • The assembly order is Sequenced as described in the Line sequencing and rule types in Assembly Control online manual topic. When the order is sequenced, you can start it from the appropriate menu of the Buffer - Assembly Orders (tiasl6520m000) session. You can arrange for a request from another line station, for an order to be started, using the Request Start - Assembly Order on Line Station (tiasc4200m000) session (or as part of workflows with the Process Trigger Definition (tiasl8100m000) session).
  • When the first line-station order is reported complete, the status of the assembly order becomes In Progress. You can report a line station order complete with the Line Station - Assembly Orders (tiasl6510m000) or Report Line Station Order Complete Using Bar Code (tiasc2211m000) session. If the lines station orders are reported complete in a different sequence from the planned sequence, LN automatically reschedules the orders.

Before you can carry out the assembly order, you must allocate assembly parts. See the Help of the Build Assembly Part Allocation (tiasc7240m000) session for more details.

You can swap orders after they have been started, as long as they still have exchangable configurations. Use the Exchange Configurations (tiasl4240m000) session.

To be Completed: If the order is reported completed, LN sets the assembly order to To be Completed status.

Completed: As soon as Warehouse Management finishes the inbound procedure for produced items that must be delivered into inventory, the assembly order will get the Completed status. When line-station orders are reported complete, you can Assembly backflushing their hours and materials.

Closed: You can close assembly orders with the Close Assembly Orders (tiasc7210m000) session (from the Assembly Line - Line Mix (tiasc2501m000) appropriate menu). When you close the assembly order, LN creates the financial transactions for that assembly order. If that is impossible, LN produces error messages. The WIP transfer bookings are recorded in the calculation office of the assembly order.

Serialized items in assembly control

The as-built structure for assembly lines is generated when you have confirmed the line sequence. If you are using serialized items (that is, the Serialized check box is selected in the Items - General (tcibd0501m000) session), the serial numbers (for example the VIN of a car) are generated at this stage.

The following actions you perform on assembly orders, affect the status of the as-built structure (that is, the serial numbers) of the serialized items of the assembly order:

  • Confirm line sequence.
  • Report assembly order complete.
  • Close assembly order.
  • Reopen assembly order.
  • Undo completed line station order.
