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. This data is used to compute order lead times, to plan production orders, to calculate standard costs, and so on. 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. 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 appropriate menu of this session, or clicking Update Order Lead Time in the Item - Production (tiipd0101m000) details session. Note
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
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:
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:
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 Routing Parameters (tirou0100m000) session is selected.
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.
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
DMS on Completion If this check box is selected, direct material supply (DMS) planning will be run when the operation is reported complete. 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 on a work center. The unit is per hour or per minute depending on the Production Rate Time Unit field in the Routing Parameters (tirou0100m000) session. The rate is derived from the cycle time as they are reciprocative. If the Use Production Rates parameter in the Routing Parameters (tirou0100m000) session is selected, you can enter the production rate, and the cycle time will be derived. Note If the Use Production Rates check box in the Routing 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:
Allowed values 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 The factor that is multiplied with the subcontracting base rate to determine the cost of subcontracting. 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 Routing 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 Routing 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 ... to start the Change Order (dmchm0150m005) session. Expiry Change Order The change order (CO) that defines the expiry date of the operation. Click ... 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.
Validate Sequence Validates the values of the Next field. Note: Only visible operations are checked if the View Effective Oprs view is selected. Expired or deleted operations are only taken into account if the View All Operations view is selected during validation. Example: Operation 20 follows operation 10, it was valid yesterday. The operation is visible when the View All Operations option is selected, and will validate if the Validate Sequence is selected.
