Product

The product ID.

Site

The site for which the routing is defined.

Routing

The sequence of operations required to manufacture an item.

For each operation, the reference operation, machine, and work center are specified, as well as information about setup time and cycle time.

Revision

The routing revision to which the related routing operation applies.

Status

The status of the routing.

Effective Date

The date the routing becomes effective.

Routing Quantity

The quantity of product on which the cycle time is based.

Standard Routing

If this check box is selected, the operation sequence is linked to a standard routing for the selected item and site combination. and may apply to several items. The Standard Routing Code field contains the standard routing code.

Related topics

Minimum Quantity

The minimal quantity of product for which the routing is used.

Maximum Quantity

The maximal quantity of product for which this routing is used.

Reference Operation Text

If this check box is selected, text is present related to the production order.

Order Lead Time

The production time of an item expressed in hours or days, based on the lead time elements as defined in the routing operations.

Operation Text

If this check box is selected, text is present related to the operation.

Operation

The operation ID.

Next Operation

If you defined a network routing, the operation that is specified in this field must be performed after the current operation.

Note

This field is visible if the Allow Parallel Operations in Routing check box in the Job Shop Master Data Parameters (tirou0100m000) session is selected.

  • Regular routing

    If you do not define a network routing, the Next field must be 0 (zero) for all routing operations. In that case, the operations are performed in order of operation number, for example, 10 - 15 - 20 - 40.

  • Network routing

    If you define a network routing, the following conditions apply:

    • Exactly one operation is the end operation. For the end operation, the Next field is 0 (zero).
    • The operation number of the next operation must be greater than the number of the current operation. For example, operation 40 must not follow operation 50.

    LN does not automatically check these conditions. To check whether the routing meets the conditions, on the appropriate menu, click Validate Sequence.

    When a production order is created, LN validates the routing and stops the process if the routing is incorrect.

Standard Configuration

If this check box is selected, the routing is part of an item’s standard configuration. The costs related to the routing are included in the standard cost price. If the Standard Configuration check box is cleared, the routing is not part of an item’s standard configuration. The costs related to the routing are not included in the standard cost price.

The Standard Configuration check box in combination with the setting of the Valid check box in the Exceptions (tcuef0105m000) session indicates whether the routing is used for a specific effectivity unit.

  • If the Standard Configuration check box is selected, and the Valid check box is cleared for an exception linked to the routing, the routing will be omitted for a specific effectivity unit or requirement.
  • If the Standard Configuration check box is cleared, and the Valid check box is selected for an exception linked to the routing, the routing will be added for a specific effectivity unit or requirement.
Note

If the routing has exceptions attached, but you do not want to use the exceptions, for example, for selling spare parts, or for an end item which is not unit-effective, then you can clear this check box.

Reference Operation

The reference operation code.

Reference Operation Machine Type

The code of the machine type the reference operation is specified for.

Note

You can specify the same reference operation for one or more machine types, sites or capacity groups.

Reference Operation Site

The site for which the reference operation is specified.

Reference Operation Work Center

The code of the work center the reference operation is specified for.

Machine Type

The sort of machine that is used during production.

Work Center

A specific production area consisting of one or more people and/or machines with identical capabilities, that can be considered as one unit for purposes of the capacity requirement planning and detailed scheduling.

Work Center Site

The code of the site to which the work center belongs. Only for subcontracting work centers, that can deviate from the site of the routing.

Fixed Setup Time

The sequence independent time required to set up or change over a machine in order to start running the machine.

Setup Scrap

Unusable or rejects of intermediate products, for example, because of faulty components, or products lost in cutting and sawing operations.

The gross requirements and/or an operation's input quantity must be increased to account for anticipated scrap.

For an operation, you can define planned scrap as a fixed quantity (setup scrap), or as relative loss via discrete yield.

Yield Type

Determines if and how lost products come out of production if the yield percentage is below 100%.

Two yield types are available:

  • Discrete
    Lost products come out of production as rejected products.
  • Continuous
    Lost products disappear completely, for example, through evaporation.

Allowed values

Yield Type

Yield Percentage

The usable output from a operation expressed as a percentage of its input.

Example 1: An operation in the production process for light bulbs has a yield of 98%. So, out of every 100 light bulbs produced, 98 are good on average. The remaining light bulbs are faulty, and will therefore be rejected.

Example 2: Steel wires are twisted together to produce a steel cable. Due to the twisting, the cable is 10% shorter than the wires from which it is produced. So, the yield is set to 90%.

In case operations are defined, yield needs to be defined per operation.

Exceptions Present

If this check box is selected, exceptions are linked to this routing. In other words, the routing is unit effective controlled. If you delete the routing's exceptions in the Unit Effectivity module, the check box is cleared.

Note

You cannot define exceptions for a standard routing.

Setup Time

The time required for setting up or changing over a machine before you start running the machine. Setup time can be long, for example, if you change over from using black paint to using white paint. Setup time can be short, for example, if you change over from using white paint to using yellow paint. The setup time must indicate an average of all possible setup times.

Labor Resources for Setup

The number of employees needed for setup, expressed in fulltime equivalent.

Cycle Time

The (average) time between completion of two separate units of production. For example, the cycle time of motors assembled at a rate of 120 per hour is 30 seconds.

Labor Resources for Production

The number of employees needed, expressed in fulltime equivalent.

Production Rate

The number of units for which the task can be performed per unit of time on a work center. The unit is per hour or per minute depending on the Production Rate Time Unit field in the Job Shop Master Data Parameters (tirou0100m000) session. The rate is derived from the cycle time as they are reciprocative.

If the Use Production Rates parameter in the Job Shop Master Data Parameters (tirou0100m000) session is selected, you can enter the production rate, and the cycle time will be derived.

Number of Machines

The number of machines that are available for production on the work center. This value can be calculated and updated in the Calculate Resources (tirou0201m000) session.

LN searches for all machines allocated to a work center by means of the Machines (Machine Types) (tirou0102m000) session. The number of machines for a work center is calculated as follows:

number of machines = sum of weekly capacities of all machines linked to work center / weekly capacity of work center

The work center's weekly capacity is defined in the Week Capacity [Hours] field of this session.

The number of machines and the number of operators that is linked to a work center is used to calculate the work center's available capacity.

Example

Work center A40 hrs/week
Machine A40 hrs/week
Machine B60 hrs/week

 

Number of machines = (40+60)/40 =
				  2.50
Note

Only available if the value of the Job Shop by Site parameter is Inactive in the Implemented Software Components (tccom0100s000) session.

Process Time

The process time is the time between completion of two separate units of production on a machine. If an operation is processed on two machines, and has a cycle time of 4 minutes, the process time will be 8 minutes.

Queue Time

The amount of time that an order remains at a work center before setup, or work is performed.

The queue time is used in lead time calculation. The queue time is expressed in days or hours. The days or hours must be interpreted as days and hours in the working time calendar that is linked to the work center.

If the Time Unit field is Days, LN rounds the entered values of the lead times to integer values.

Backflushing

If this check box is selected, the materials and/or hours used during the operation are automatically backflushed after an operation is reported as complete.

Serialized items

Serialized items can only be backflushed if in the Items - Warehousing (whwmd4500m000) details session the Serials in Inventory check box is cleared, and the Register Serial Issue During As Built field is Yes. In all other cases, serialized items cannot be backflushed.

If the serialized item is lot-controlled, the lot from which the items are backflushed is based on the outbound method ( Last In First Out (LIFO), First In First Out (FIFO)) as is defined in the Items - Warehousing (whwmd4500m000) details session.

Wait Time

The time that an order remains at a work center after an operation is completed until it is moved to the next operation.

LN does not plan wait times according to a specific calendar. Planning of the wait time is based on a 7 * 24 hours week schedule.

A typical example is the time required for drying after the application of paint.

When LN calculates the start times and end times of planned orders based on the routing, LN considers the wait time. The wait time is expressed in days or hours. The days or hours do not relate to a calendar. The availability of time is considered as 24 hours a day, seven days a week.

If the Time Unit field is Days, LN rounds the entered values of the lead times to integer values.

The plan buffer created by the wait time enables you to build in a certain tolerance between successive operations, which makes it possible to shift operations in case planning must be adjusted.

Note

This field is not accessible if the Work Center Type field is Costing Work Center, Line Station or Buffer.

Count Point

If this check box is selected, the operation is a count point.

Subcontracting with Material Flow

If this check box is selected, only subcontracting with material flow is used to produce the item.

Move Time

The time that a semifinished good is in transit from one operation to the next operation. After the last operation, the move time is the time required to transfer the finished good to the warehouse.

Move time is one of the lead-time elements LN plans according to a specific calendar.

If the Time Unit field is Days, LN rounds the entered values of the lead times to integer values.

Standard Configuration

If this check box is selected, the routing is part of an item’s standard configuration. The costs related to the routing are included in the standard cost price. If the Standard Configuration check box is cleared, the routing is not part of an item’s standard configuration. The costs related to the routing are not included in the standard cost price.

The Standard Configuration check box in combination with the setting of the Valid check box in the Exceptions (tcuef0105m000) session indicates whether the routing is used for a specific effectivity unit.

  • If the Standard Configuration check box is selected, and the Valid check box is cleared for an exception linked to the routing, the routing will be omitted for a specific effectivity unit or requirement.
  • If the Standard Configuration check box is cleared, and the Valid check box is selected for an exception linked to the routing, the routing will be added for a specific effectivity unit or requirement.
Note

If the routing has exceptions attached, but you do not want to use the exceptions, for example, for selling spare parts, or for an end item which is not unit-effective, then you can clear this check box.

Subassembly

An intermediary product in a production process that is not stored or sold as an end product, but that is passed on to the next operation.

For subcontracting purposes, a manufacturer can send a subassembly to a subcontractor to carry out work on the subassembly. This subassembly has its own item code defined in the Item Base Data.

After work is finished, the subcontractor sends the subassembly back to the manufacturer. Also this reworked subassembly has its own item code defined in the Item Base Data.

Use Transfer Batch

If this check box is selected, you can start work on a routing operation before the preceding operation is finished.

DMS on Completion

If this check box is selected, direct material supply (DMS) planning will be run when the operation is reported complete.

Subassembly Warehouse

The warehouse from which the subassembly is sent or in which the subassembly is received.

Transfer Batch Quantity

The quantity of product that must be finished to start the next routing operation if the Use Transfer Batch check box is selected.

Fixed Duration

An indication whether the production time is fixed, or is dependent on the order quantity. If the production time has a fixed duration, then it equals the cycle time. If it is indicated that the production time does not have a fixed duration, the cycle time is multiplied by the order quantity.

For example, baking one bread in the oven takes one hour. Baking a hundred breads at once also takes a fixed duration of one hour.

Container

A vessel used to store or move material.

Container Method

The shipment method how to handle items in the container. For instance, stack should be less than 10 tiers high.

Container Quantity

The quantity of items stacked in the container.

Number of Kanbans

The number of kanbans that is used in the pull system.

Description on Kanban

The description of the inter-operation kanban that serves as an identification for the kanban.

Activity

The project activity defined in the Activities (tipcs4101m000) session to which the operation is related.

Note

Only applies to customized items.
