| # Task Relationships (tirou0104m000) A task can be performed on many work centers and on many machines. Use this session to indicate which task is performed on a specific work center, and the machine that is used to carry out the task. Related topics Tools planning and tracking Microrouting Task The task that is linked to one or more work center(s). You can only link Production tasks to a work center. Work Center The work center on which the task is performed. Related topics Work centers Machine The machine that is linked to the task. Task Relationship Description Use this field to give a description to the task relationship. Search Key The search key enables you to quickly retrieve work centers in a number of sessions. By default, ERP Enterprise displays 16 characters of the task description. These can be replaced by another text if desired. Operation Rate Code The operation rate code that is linked to the task relationship and serves as the task relationship rate. The operation rate code must be predefined in the Operation Rate Codes (ticpr0150m000) session. Operation rate codes can only be entered if the following applies: The Type of Operation Rates parameter in the Cost Price Calculation Parameters (ticpr0100m000) session is Task Relationship Rate. The work center is not a subcontracting work center. Subcontracting Rate Factor The subcontracting rate factor, together with the subcontracting base rate, determines the subcontracting costs. The value of this field depends on the Calculation Method for Subcontracting Costs field in the Subcontracting Rates (ticpr1160m000) session. If this field is Operation Rate, the following construction is possible. You can depart from a base rate for subcontracting and further specify a base rate for each operation line. Example: Subcontracting rate is 100 Subcontracting rate factor is 2 Then total cost of subcontracting is 200 Related topics Examples of subcontracting rates Routing Quantity 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. Machine Occupation The number of machines required to perform the operation. You can enter this field when you defined a machine for the selected work center in the Tasks (tirou0103m000) session. Average Setup Time The average setup time that applies to this specific task/work center relationship. 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. Production Rate The number of units for which the task can be performed per unit of time. The Production Rate Time Unit field in the Routing Parameters (tirou0100m000) session determines whether the time unit is Hour or Minute. If you have defined norm time tables, you can zoom to the Calculate Norm Time (tirou0230m000) session to calculate the production rate. Note If the Use Production Rates check box in the Routing Parameters (tirou0100m000) session is cleared, you cannot enter this field. Related topics Calculating production rate and cycle time from a norm table Calculating based on norm tables Slash Character The time unit in which the production rate is expressed. Cycle Time The cycle time that applies to this specific task/work center relationship. The cycle time is used, for example, to calculate cost prices, and to calculate order lead times. In the Task Relationships (tirou0104m000) details session, you can zoom to the Calculate Norm Time (tirou0230m000) session to calculate the cycle time. The total operation time depends on the order quantity. Related topics Calculating operation costs (man and machine hours) 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. If this check box is selected, the duration of an operation is fixed, and its production time does not depend on the batch size.
     Production time =
    			 setup time + (1 * cycle time)
Backflushing If this check box is selected, the material and spent production hours are backflushed after the task is performed. 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. Related topics Backflushing Overview of serialized items Count Point An operation in a routing where the quantity of completed and rejected items must be determined explicitly. If an operation is a count point, completion of that operation must be reported separately. The quantity completed in follow-up operations must not exceed the quantity completed in the count point. If an operation is not a count point, it can be set to Completed automatically upon completion of a follow-up operation. The quantities completed and rejected are then determined by the completed quantity in the count point. 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. 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. Extra Information Use this field to enter any additional information. Calculate Production Rate Calculates the production rate. Tools Starts the Task Relationship - Tools (tirou0115m000) session in which you can view or maintain the tools that are linked or must be linked to the task relationship. If you linked tools to a specific machine in the Machine - Tools (tirou0110m000) session and you defined a task relationship in the current session in which the machine is involved, ERP Enterprise automatically links the tools to the task relationship in the Task Relationship - Tools (tirou0115m000) session. Process Variables Starts the Task Relationship - Process Variables (tirou0116m000) session in which you can link process variables to a task relationship. Setup Classes / States Starts the Setup Classes and States by Work Center/Task (tirou0112m000) session. Update Routing Operations Starts the Update Routing Operations (tirou1204m000) session in which you can update the routing operations that make use of a task relationship that is changed in the current session. Where-Used Starts the Routing Operations (tirou1102m000) session in which you can view the routing operation(s) in which a specific task relationship is used. |
