| Routing Operations (tirou1102m000) Use this session to maintain operation data by
manufactured item and/or by 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. Main Item The code of the manufactured item. If this field is empty, the
routing is a standard routing. An item code for a manufactured item must
also be entered in the Item - Production (tiipd0101m000) session. If you want to define routing operations for a
standard routing, you must leave this field empty. Site The site ID. Note Only visible if multisite functionality is active. 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. Quantity-dependent Routing If this check box is selected, LN selects a particular routing. The selection
depends on the order quantity, therefore, the operation times for an item can
depend on the order quantity. Note This does not apply
to Generic items. Start Operation If the operation does not follow any other operation, this
field displays an indicator for a start operation. End Operation If the operation is the final operation, this field displays an
indicator for an end operation. Up to Order Quantity The production order quantity at which the routing is
adjusted. 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. You can determine the order lead time by
clicking Update Lead Time... in the menu of this session, or
clicking Update Order Lead Time in the Item - 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 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 quantity | 100 | Cycle time | 60 minutes |
In a 60 minute time span, 100 items are produced.
Consequently, the operation time of one item is 0.6 minute. 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 standard cost. / 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
- Standard Cost Calculation
- Job Shop Control
Next 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 operation is
part of an item’s standard configuration. The costs related to the routing
operation are included in the standard cost. 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. 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.
Queue Time The amount of time that an order remains at a work center
before setup, or work is performed. 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. 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 Job Shop Master Data 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: - If the Use Production Rates check box in the Job Shop Master Data Parameters (tirou0100m000) session is selected, you can compute the production
rate by zooming to the Calculate Norm Time (tirou0230m000) session.
- You can enter a value in the Cycle Time (min) field, and compute the production rate by clicking the Calculate Rate
button.
Note If the Use Production Rates check box in the Job Shop Master Data Parameters (tirou0100m000) session is cleared, you cannot maintain this
field. 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 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. 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 Occupation for Production field. Man Occupation for Production 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). Machine 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. Fixed Setup Time The sequence independent time required to set up or change over
a machine in order to start running the machine. Count Point If this check box is selected, the operation is a count point. 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. 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.
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. Physical Location Place where the operation actually takes place. Operation Text If this check box is selected, an operation text is
present. You can create an operation text in the Routing Operations (tirou1102m000) session. Task Text If this check box is selected, a text is present for
the task, which is linked in the Tasks (tirou0103m000) session. 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. Subassembly Warehouse The warehouse from which the subassembly is sent or in which
the subassembly is received. Subcontracting Rate Factor Requisition If this check box is selected, permissions for the requisition process
can be specified. Note This check box is enabled only if you select the Authorization and Security Enabled check box. 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 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. 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 default work center where the task is carried out. You can select another work
center. Machine The machine on which the
operation is performed. 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. 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. Transfer Batch Less Than Production 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 Quantity 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 Job Shop Master Data Parameters (tirou0100m000) session is Quantity, you must type a quantity in the Transfer Batch Quantity field. If the Transfer Batch Method field is Percentage, you must type a percentage. Transfer Batch Quantity 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 Job Shop Master Data Parameters (tirou0100m000) session is Quantity, you must type a quantity. If the Transfer Batch Method field is Percentage, you must type a percentage. Effective Change Order The change order (CO) that defines the effective date of the operation. Click the field to start the Change Order (dmchm0150m005) session. Expiry Change Order The change order (CO) that defines the expiry date of the operation. Click the field to start the Change Order (dmchm0150m005) 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. Expiry Date The date on which the operation line is no longer
valid. If you do not specify an expiry date, LN automatically sets the
date to its maximum value. | |
