Routing Operations (tirou1102m000)

Use this session to maintain operation data by manufactured item and/or routing. A routing consists of one or more separate operations, which are carried out in succession.

Performance aspects

The settings in this session could affect system performance and database growth. For more information, refer to Micro routing.

 

Manufactured Item

The code of the manufactured item. If this field is empty, the routing is a standard routing.

Note

An item code for a manufactured item must also be entered in the Items - Production (tiipd0101m000) session. If you want to define routing operations for a standard routing, you must leave this field empty.

Order Lead Time

order lead time

You can determine the order lead time by clicking Upd. Lead Time... in the appropriate menu of this session, or clicking Update Order Lead Time in the Items - Production (tiipd0101m000) details session.

Note
  • The value of this field is calculated based on the routing data entered in this session.
  • The lead time, as based on the cycle time and other values, is multiplied with the economic order quantity specified in the item ordering data.
Routing

The sequence of operations required to manufacture an item.

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

Routing Unit

The quantity of the manufactured item on which the routing is based. A routing quantity enables you to include very short operation times in the routing of an item.

Example
Routing quantity100
Cycle time60 minutes

 

In a 60 minute time span, 100 items are produced. Consequently, the operation time of one item is 0.6 minute.

Inventory Unit

The unit of measure in which the inventory of an item is recorded, such as piece, kilogram, box of 12, or meter.

The inventory unit is also used as the base unit in measure conversions, especially for conversions that concern the order unit and the price unit on a purchase order or a sales order. These conversions always use the inventory unit as the base unit. An inventory unit therefore applies to all item types, also to item types that cannot be kept in stock.

Start Operation

If the operation does not follow any other operation, this field displays an indicator for a start operation.

Related topics

End Operation

If the operation is the final operation, this field displays an indicator for an end operation.

Related topics

Operation

One of a series of steps in a routing that are carried out successively to produce an item.

The following data is collected during a routing operation:

  • The task. For example, sawing.
  • The machine used to carry out the task (optional). For example, sawing machine.
  • The place where the task is carried out (work center). For example, woodwork.
  • The number of employees required to carry out the task.

This data is used to compute order lead times, to plan production orders and to calculate cost prices.

Sequence Number

The sequence number of the operation. This number is based on the effective/expiry dates, and is used to distinguish between operations.

The effectivity and expiry date for operations are used in:

  • Enterprise Planning
  • Cost Price Calculation
  • Shop Floor Control
Next Operation

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

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

Regular routing

If you do not define a network routing, the Next Operation 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 Operation 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.
Note

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.

Task Data
Task

An activity to manufacture or repair an item. For example, sawing, drilling, or painting.

A task is carried out on a work center, and can be related to a machine.

Work Center

The work center in which the operation is carried out.

Note

You can only change the work center if the operation has one of the following statuses:

  • Planned
  • Ready to Start
  • You cannot change the work center if some quantities have already been reported completed.
  • You cannot change another type of work station into a line station or buffer.
  • You can only change a subcontracting work station if no purchase orders were generated or if already generated purchase orders can be deleted or canceled.
Machine

The machine on which the operation is performed.

Operation Lead Times
Queue Time

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

Queue Time

The time unit in which your express the queue time.

If the time unit is Hours, you can enter fractions. If the time unit is Days, LN rounds the entered values to an integer.

Fixed Setup Time

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

Average Setup Time [Min]

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.

Production Rate

The number of units for which the task can be performed per unit of time (per hour or per minute, depending on the Production Rate Time Unit field in the Routing Parameters (tirou0100m000) session), for a combination of an X-axis value and a Y-axis value from a norm table.

You can compute the production rate in two ways:

Note

If the Use Production Rates check box in the Routing Parameters (tirou0100m000) session is cleared, you cannot maintain this field.

/

The unit that is used to specify the physical quantity time.

Cycle Time [Min]

In LN, the 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.

The cycle time is also equal to the time that a product stays in one position on a assembly line, or the time that an operation is carried out on an item in a work station (excluding setup time).

You can zoom to the Calculate Norm Time (tirou0230m000) session to calculate the production rate.

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.

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 to transfer the finished good to the warehouse.

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

Execution details
Man Occupation for Setup

The number of persons required to accomplish the operation's setup. Enter the number of persons required to accomplish the operation in the Man Occup. for Prdn field.

Man Occup. for Prdn

The number of persons required to accomplish the operation. Enter the number of persons required to accomplish the operation's setup in the Man Occupation for Setup field. For more information about changing this field, refer to the session Help of Routing Operations (tirou1102m000).

Mach. Occupation

This field indicates how many machines are required to carry out the operation. For more information about changing this field, refer to the session Help of Routing Operations (tirou1102m000).

This field is enabled when you have defined a machine for the selected work center in the Tasks (tirou0103m000) session.

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.

Effective Change Order

The change order (CO) that defines the effective date of the operation.

Click ... to start the Change Order (dmchm0150m005) session.

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.

Effective Date

The date when the validity period of an entity starts.

In the case of effectivity control the reference date is checked against the effective date. If the reference date is greater than or equal to the effective date the configuration entity is valid.

Count Point

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

in process by CHM

If this check box is selected, the operation is under change management control. If a change order is linked to the operation, and the change order is not approved yet, LN selects this check box.

Change management keeps track of the effective and expiry dates of an operation for a defined procedure.

DMS on Completion

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

Standard Configuration

If this check box is selected, the routing operation is part of an item’s standard configuration. The costs related to the routing operation are included in the standard cost price. If the Standard Configuration check box is cleared, the routing operation is not part of an item’s standard configuration. The costs related to the routing operation 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 operation 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 operation, the routing operation 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 operation, the routing operation will be added for a specific effectivity unit or requirement.
Note

If the routing operation 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.

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.
  • The Standard Configuration check box and the Exceptions present check box cannot be selected at the same time.
Scrap Quantity

Unusable material or rejects of intermediate products, for example, because of faulty components, or products lost in cutting or sawing operations. The gross material requirements and/or an operation's input quantity must be increased to account for anticipated scrap.

In the BOM, you can define scrap as a percentage of the net material requirements, which is the scrap factor, and as a fixed quantity, which is the scrap quantity. A scrap quantity is mostly used to define the amount of material that is lost every time when you start producing, for example, to test the equipment.

For an operation, you can only define the scrap as a fixed quantity.

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%.

Extra Information

Use this field to enter additional information.

Sctr. Rate Factor

The subcontracting rate factor, together with the subcontracting base rate, determines the cost of subcontracting.

The value of this field depends on the setting of the calculation method for the subcontracting rate as recorded in the Subcontracting Rates (ticpr1160m000) session.

If this field reads Operation Rate, the following construction is possible. You may depart from a base rate for subcontracting and further specify that base rate for each operation line.

Example

Subcontracting rate is 100

Subcontracting rate factor is 2

The total cost of subcontracting is 200

Expiry Change Order

The change order (CO) that defines the expiry date of the operation.

Click ... to start the Change Order (dmchm0150m005) session.

Expiry Date

The date on which the operation line is no longer valid.

The latest possible expiry date is 19 January, 2038. If you do not enter an expiry date, 01/19/38 is automatically displayed.

Transfer Batch Less Than Production Batch
Transfer < Prdn Batch

The quantity or percentage of items for which an operation must be finished before you can start with the next operation. Even though an operation is not yet finished for all items in a production order, you can start the next operation for the items that are already finished.

In a production environment where kanban is used, the transfer batch quantity equals the kanban size (which is the standard container, or the standard lot size).

The transfer batch quantity replaces the previously used concept of overlap percentage on operation.

If this check box is selected, you can start the next operation before the complete production batch is finished. You must enter a value in the Transfer Batch Qty field, which indicates when the next operation can be started. If this check box is cleared, the next operation starts when the complete production batch is finished.

If the Transfer Batch Method field in the Routing Parameters (tirou0100m000) session is Quantity, you must type a quantity in the Transfer Batch Qty field. If the Transfer Batch Method field is Percentage, you must type a percentage.

Transfer Batch Qty

The quantity or percentage of items for which an operation must be finished before you can start with the next operation. Even though an operation is not yet finished for all items in a production order, you can start the next operation for the items that are already finished.

In a production environment where kanban is used, the transfer batch quantity equals the kanban size (which is the standard container, or the standard lot size).

The transfer batch quantity replaces the previously used concept of overlap percentage on operation.

If the Transfer Batch Method field in the Routing Parameters (tirou0100m000) session is Quantity, you must type a quantity. If the Transfer Batch Method field is Percentage, you must type a percentage.

Activity

You can zoom to the Activities (tipcs4101m000) session to select an activity. An activity can be an operation in network planning.

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 Qty

The quantity of items stacked in the container.

Number of Kanbans

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

Dscr on Kanban

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

Physical Location

Place where the operation actually takes place.

Subcontracting
Subcontracting Rate Factor

The subcontracting rate factor, together with the subcontracting base rate, determines the cost of subcontracting.

The value of this field depends on the setting of the calculation method for the subcontracting rate as recorded in the Subcontracting Rates (ticpr1160m000) session.

If this field reads Operation Rate, the following construction is possible. You may depart from a base rate for subcontracting and further specify that base rate for each operation line.

Example

Subcontracting rate is 100

Subcontracting rate factor is 2

The total cost of subcontracting is 200

Subcontracting with Material Flow

If this check box is selected, LN supports the physical and administratieve flow of material and subassemblies to the subcontractor.

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.
