Work Centers (tirou0101m000)

Use this session to list and maintain work centers. Work center data is used for cost estimating and for planning purposes.

On the appropriate menu you can choose:

Note

You cannot delete a work center if:

  • The work center is a main work center with one, or more sub-work-centers.
  • The work center is still active in LN.

 

Work Center

The work center ID.

When you define a work center code, you must find out which work center influences the cost estimates of production orders.

The Type of Operation Rates field in the Standard Cost Calculation Parameters (ticpr0100m000) session determines whether a work center has an influence on the estimated costs. The Type of Operation Rates field can be set to either Task Relationship Rate or Work Center Rate.

The number of work centers need not match with the number of physical work centers in your organization, as not every physical work center has an impact on estimated costs.

In the Production Planning (tisfc0110m000) session, you can modify the planning by having an operation carried out at another work center. In that case, the resource units must be similar.

Note
  • The work center cannot be deleted if used anywhere else in LN.
  • Before you can define a work center you must define a department in the Departments (tcmcs0565m000) session.
Work Center Type

The work center type.

Description

The work center description.

Production Department

An organizational unit responsible for the production of a set of work centers or work cells

Note

The work centers or cells of a production department are often located in one physical location, for example a production hall.

SubcontractorIndependent

If this check box is selected, the work center, which is defined as Subcontracting Work Center, has no linked subcontractor.

Note

This check box allows users to model scenarios and define master data for production of items with subcontracted tasks or parts, while the subcontractor is yet to be determined.

Subcontractor

The subcontractor, if the Work Center Type field is Subcontracting Work Center.

Note

You cannot specify this field if the SubcontractorIndependent check box is selected in the Work Centers (tirou0101m000) session.

Enterprise Unit

A financially independent part of your organization that consists of entities such as departments, work centers, warehouses, and projects. The enterprise unit's entities must all belong to the same logistic company, but a logistic company can contain multiple enterprise units. An enterprise unit is linked to a single financial company.

When you carry out logistic transactions between enterprise units, these are posted in the financial companies to which each enterprise unit is linked. You can define intercompany trade relationships between enterprise units to determine the terms for internal trade between these units. To use invoicing and pricing between enterprise units, you must link the enterprise units to internal business partners.

You can use enterprise units to do separate financial accounting for parts of your business. For example, you can define enterprise units for separate parts of your organization that belong to one logistic company, but that are located in different countries. The accounting of each enterprise unit is performed in each country's national currency, and in the financial company linked to the enterprise unit.

You can change the work center's enterprise unit in the Departments (tcemm1124m000) session. However, once you have set up the multisite structure, you can no longer change the enterprise unit.

Actual Calendar

The calendar and availability type combination that is used by the work center manufacturing a production order.

Note
  • If a work center calendar is specified, the actual calendar equals the work center calendar. If no work center calendar is specified, the next applicable calendar is used such as that of the related production department.
  • You can see the level at which the actual calendar is defined in the Origin field.
ParentWork Center

The main work center linked to the work center.

If the work center is a sub work center of a main work center, you must enter the code of the main work center.

If you use shared work centers, the secondary work center is always a main work center, even if the primary work center is a sub work center.

Critical Capacity for Planning

Specify which capacity is critical when planning. The specified capacity is used by Enterprise Planning and Project Control network activities:

  • Enterprise Planning
    Dependent on the value, Enterprise Planning uses man capacity or machine capacity to express the capacity use in the resource master/order plan.
  • Project Control network activities
    Dependent on the value, PCS network activities use man capacity or machine capacity to calculate the value of the Aggr. Estim. Cap. [H] field in the Activities (tipcs4101m000) session and the Activity Overview by Project (tipcs4502m000) session.
Note

JSC does not use this field because in JSC the capacity use is always expressed in terms of man capacity and in terms of machine capacity.

Allowed values

Critical Capacity Type

Work Center Calendar

A set of definitions, that are used to build a list of calendar working hours. A calendar is identified by a calendar code and availability type combination.

The field is not applicable, when the Work Center Type field is set to Line Station or Buffer.

Origin

The ID of the session where the actual calendar is defined.

Shop Floor Warehouse

A warehouse that stores intermediate inventory in order to supply work centers. A shop floor warehouse is linked to an individual work cell, an assembly line, or one or more work centers. A shop floor warehouse can be supplied with goods using replenishment orders, or by pull-based material supply.

The pull-based material supply methods are:

  • Order Controlled/Batch (only applicable in Assembly Control).
  • Order Controlled/SILS (only applicable in Assembly Control).
  • Order Controlled/Single (only applicable in Job Shop Control).
  • KANBAN.
  • Time-Phased Order Point.

The items stored in the shop-floor warehouse are not part of the work in process (WIP). When items leave the shop floor warehouse for use in production, their value is added to the WIP.

You can only enter a value if the Use of Shop Floor Warehouses check box in the Production Order Parameters (tisfc0100s000) session is selected.

The value of the Warehouse Type field in the Warehouses (tcmcs0103s000) session must be set to Shop Floor.

Backflush Employee

The employee number to which hours are posted in People using backflushing.

Operation Rate Code

The code linked to the work center and used as the work center rate.

Note

You must define operation codes in the Operation Rate Codes (ticpr0150m000) session.

This field is only enabled if:

  • The Type of Operation Rates parameter in the Standard Cost Calculation Parameters (ticpr0100m000) session is Work Center Rate or Task Relationship/Work Center Rate.
  • The Work Center Type is not Subcontracting Work Center.
Costing Work Center

A work center, linked to a planning work center, that is used to calculate the end item unit costs, WIP transfers, and production results used to hold the financial transactions related to production orders.

The link between a costing work center, and a planning work center enables you to replan production order operations again. If required, you can change the work center that is used to carry out an operation without modifying the costing process.

Note

If the work center is of the Sub Work Center type, the costing work center of the sub-work-center's main work center is automatically displayed. However, you can change the costing work center in this field.

Related topics

Operation Rate Code of Costing W/C

The code linked to the costing work center and used as the costing work center rate.

Related topics

Week Capacity [Hours]

The weekly capacity of each resource unit in the work center. This value is used to calculate the normal capacity of a work center by week, which is displayed in work center utilization reports.

Basic Day Capacity[Hours]

The daily capacity of each resource unit in the work center. This value is used to calculate the normal capacity of a work center by day, which is displayed in work center utilization reports.

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 (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
Number of Operators

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

Each work center is a department. LN searches for all operators assigned to the department by means of the Employees - General (tccom0101m000) session, and sums up their weekly capacities. The number of operators for a work center is calculated as follows:

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

The employees' weekly capacities are entered in the Employment field in the Employees - People (bpmdm0101m000) details session. The work center's weekly capacity is defined in the Work Centers (tirou0101m000) details session.

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

Example

Current date: 2000-11-07

Work center A: 40 hrs /week

EmployeeFirst dateLast dateHrs/week
A2000-01-012000-12-3140
B2000-01-012000-10-3120
C2000-01-01030

 

Number of operators = (40 + 30) /40 = 1.75, because the hours of employee A is 40 and employee C is 30. The hours of employee B are ignored as the Last Date is set to 2000 -10 -31 (the date earlier to current date), and hence B is no longer the employee for the date set.

Time Unit

The time unit in which Wait Time and Queue Time are expressed. The time unit of the sub-work-center can be the same as the time unit of its main work center.

If the time unit relates to the queue time, Days and Hours must be interpreted as days and hours in the working time calendar that is linked to the work center. If the time unit relates to the wait time, no calendar is used. The availability of time is considered as 24 hours a day, 7 days a week.

Allowed values

  • Hours
    Lead times are expressed in hours and fractional values are allowed.
  • Days
    Lead times are expressed in days and fractional values will be rounded to integer values.
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.

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.

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.

Constraint Type

Specify the type of constrained type for the work center.

Allowed values

  • Time Fence
  • Plan Horizon
Constraint Time Fence

A reference date against which processes or statuses are evaluated.

Example

The assembly order time fence on an assembly line defines the end date of the period for which assembly orders must be created. If this time fence is 100 days, assembly orders must be created for product variants whose planned offline date is between now and 100 days. Similarly, a time fence can define when line station orders must be frozen, updated, and so on.

Desired Queue

The difference between the output and input of a work cell required by the user. This value is the default for initial queue calculations.

Use rough PCS capacity requirement

In PCS network planning, the work center's capacity can be consumed by:

  • PCS rough capacity, which is defined in the Activities (tipcs4101m000) session
  • Capacity required for JSC production orders and planned production orders in Enterprise Planning.

This check box determines how the work center's capacity is consumed:

  • If this check box is cleared, the work center's available capacity is consumed by the capacity required for the JSC production orders and planned production orders in Enterprise Planning. The rough capacity requirements defined in the Activities (tipcs4101m000) session are not taken into account.
  • If this check box is selected, the PCS rough capacity defined for activities in PCS, and the capacity required for JSC production orders and planned production orders in Enterprise Planning are subtracted from the work center's available capacity. Therefore, double consumption of work center capacity occurs.
Print Instructions

If you use a microrouting, you can define instructions for production orders for each operation and for each operation step. If the value of this field is Yes, those instructions are printed.

You can only use Not Applicable as a value if the Work Center Type is Sub Work Center. Consequently, the sub-work-center inherits its main work center's value of the Print Instructions field.
