Use this function to define a production resource that is to be used for an operation in a routing.

A work center can be defined as a machine used in your manufacturing processes, a labor resource, or an operation in a routing that is subcontracted to an external supplier.

Your work center definitions are central to your production planning:

  • Work centers are used for planning load times (preparation time, waiting time, and post run time), and tracking production time.
  • Work centers provide capacity data, efficiency data, and shrinkage percentages.
  • Should a breakdown or a bottleneck occur, replacement, or alternative work centers can be nominated, and prioritized.
  • Work center costings can be managed using a link to a costing dimension.
  • Multiple work centers can be linked with the same cost type, to then link with Project management. In a labor context, a cost type defines the types of labor resource that can affect a project, such as operator costs.

Fields

The following fields are present on this tab :

  • Work center (field WST)

Use this field to identify this work center. This is a production resource at which a routing operation is carried out. It is used for planning load times (preparation time, waiting time and post run time), and tracking production time.

You must define the manufacturing site at which this work center is operated, and associate this work center with a group of similar work centers.

Use this field to define the manufacturing site at which this work center is operated.

  • Description (field WSTDESAXX)

This long description is used as a title in screens and reports.

By default the short title, the long title or the column header of a data are recorded (on creation/update) in the connection language of the user.
You can add your translation in another language using the Translation function:

  • Click Translation from the Actions icon in the corresponding field.
  • In the Translation window, add a new language code with the translation in this language.

A user who logs on with this language will view the short description, long description or column header in their connection language if a translation exists. Otherwise, these descriptions will be available in the folder language.

SEEINFOThe connection language must be defined as a default language for thefolder.

  • Short description (field WSTSHOAXX)

Short title used in the screens and reports. This title is recorded in your connection language.

By default the short title, the long title or the column header of a data are recorded (on creation/update) in the connection language of the user.
You can add your translation in another language using the Translation function:

  • Click Translation from the Actions icon in the corresponding field.
  • In the Translation window, add a new language code with the translation in this language.

A user who logs on with this language will view the short description, long description or column header in their connection language if a translation exists. Otherwise, these descriptions will be available in the folder language.

SEEINFOThe connection language must be defined as a default language for thefolder.

Use this field to identify the group of work centers to which this work center belongs. Work center groups are used to review workloads.

  • Work center type (field WSTTYP)

This field identifies the type of operation that is performed at this work center. This might be a machine, a labor resource, or a subcontracted operation. Work centers of type Subcontracting are managed externally by subcontract suppliers.

Tab Management

Presentation

You use this section to define control parameters for this work center. These include the workers shift pattern, the number of operators, and for work centers of type Machine, whether this work center must continue running whilst the operator is on a break.

Close

 

Fields

The following fields are present on this tab :

Parameters

Use this field to assign the workers shift pattern for this work center. For example, a time structure that defines a start time at 08:00 and a end time at 17:42, that is, 7 hours and 42 minutes of work.

Should you need to change a work center or its capacity once it is being used in the manufacturing process, you can change the weekly structure or assign a different weekly capacity using the Work centers modification function (FUNTDUPDW) or Variation of capacity function (FUNTDUVAR), as appropriate.

   

Calendars are used for calculating the capacity of a work center.
A calendar can be common to multiple work centers or specific to an individual work centre. It is made up of a succession of periods linked to weekly schedules.

  • Costing dimension (field VLTCCE)

Use this field to link this work center with your financial accounting. The costing dimension provides financial information on which the calculation of the provisional costs, and the production cost price are based.

  • No. of resources (field WSTNBR)

Use this field to define the number that are required for an operation at this particular production resource. For example, if three people are needed to operate this (labor) work center, type in 3.

You must set this field to 1 if you are using the generic Finite scheduleradvanced interface. The Finite scheduler interface provides an integration connector to connect to Sage X3 Web Scheduling or to any web scheduling solution developed by an ISV (independent software vendor) for either cloud or on-premises solutions. The advance interface is active if the GFSA - Finite scheduler advanced activity code is active. Sage X3 Web Scheduling cannot optimize production times when multiple resources are assigned to a work center. This is a limitation of Sage X3 Web Scheduling.

  • Automatic closing % (field CLEPCTAUT)

This percentage defines the threshold being applied to automatically close the materials during production tracking.

For instance, if the value is 95% and the material requirement is 200 UN, the system will suggest to close the material if the consumed quantity is greater than or equal to 190 UN.

  • Location (field STOLOC)

Use this field to define the default location of this production resource at the defined manufacturing site.

This value is used by stock movement transactions such as receipts, issues, and location changes. It is also used when a component is assigned to an operation where the allocation rule filters by location.

  • Qualification level (field QLFLEV)

The qualification level is a 10-character alphanumeric reference field only.

Block number 2

  • Run during employee break (field RUNBRKFLG)

Select this check box if this work center must continue running whilst the operator is on a break, or an exclusive indirect task.

This field is only available for work centers of type Machine.

  • Constraint (field CONSTRAINT)

A constraint work center is considered by the optimization function as a work center with finite capacity, whilst a non constraint work center has infinite capacity.

Select this check box to indicate that this work center is associated with constraints in terms of finite capacity (machine or labor).

  • RCCP (field RCCP)

Rough Cut Capacity Planning in the translation of the French abbreviation "PGC" (for "Planification Globale des Capacités").

This check box characterizes this work center. Select this check box if an operation at this work center is identified as being critical during the manufacturing process. A critical operation is particularly significant when generating macro-routings.

Performances

  • % efficiency (field EFF)

Efficiency is a way to measure compliance to the preset standards. It can be calculated over a given period by work center: Standard hours calculated for a given production divided by the actual hours worked.
Efficiency makes it possible to correct the standard times of the routing (multiplying factor) according to the used resource.

Two efficiency rates are managed depending on the following:

  • Work center: The rate is applied to all the routing operations that will take place at the work center.
  • Routing operation: The rate only applies to the considered operation.

If both factors are entered, they add up.
The calculated operating time is corrected in the following way: work center efficiency * operation efficiency * time.

The WSTEFFINH - Work center efficiency history parameter (GPA chapter, MIS group) is used to specify whether the efficiency defined at work center level should be used on the routing operation.

  • If WSTEFFINH is set to Yes, the efficiency entered in the work center is suggested by default when creating the routing operation with this work center. The calculated runtime = runtime entered * 1 / operation efficiency.
  • If WSTEFFINH is set to No, the efficiency entered in the work center is combined with that entered in the routing operation. The calculated runtime = runtime entered * 1 / work center efficiency * 1 / operation efficiency.


  • Shrinkage in % (field SHR)

This percentage is used to balance the quantities on the production operations based on the released quantity.

It is possible to introduce a shrinkage percentage on the work center, which is used to weight the planned runtimes for an operation using this work center by a loss or gain on the quantity produced for the work center.

Totals

  • Expected time (field EXTHOUTIM)

This field displays the total estimated time for operational work at this work center.

  • Actual time (field CPLHOUTIM)

This field displays the total operational time at this work center.

Project

Use this field to assign this work center to a specific cost type. Cost types are used by Project management. In a labor context, a cost type defines the types of labor resource that can affect a project such as operator costs.

Close

 

Tab Variation

Presentation

You use this section to control capacity for this work center.

Work center capacity comprises multiple elements:

  • A general weekly structure, which defines the available periods for the work center. This is defined in the Management section.
  • Periods of non-availability, such as when the manufacturing site is closed, or an operator is on annual leave.
  • The number of work center resources generally available.

You use this section to define exceptions to the availability, or capacity of this work center. For example, to define a specific date this work center is not available because of maintenance. Alternatively, a labor work center might have a variation because a mechanic is on leave, or only 2 workers are available instead of the normal 3.

You can attach a reason for a variation. Reason codes are defined in miscellaneous table 801 - Capacity variation reasons.

 

Fields

The following fields are present on this tab :

Grid Capacity variation

  • Start date (field STRDAT)

Type in, or select the first date of the period of non-availability of this work center. For example, a specific date this work center is not available because of maintenance, or the first date of an operator's leave of absence.

  • End date (field ENDDAT)

Type in, or select the last date of the period of non-availability of this work center. For example, a specific date this work center is not available because of maintenance, or the last date of an operator's leave of absence.

 

Use this field to define the workers shift pattern against which this exception to the availability of this work center applies. The default shift pattern is the shift pattern defined in the Structure field (TWD).

  • No. of resources (field VARWSTNBR)

For this exception to the availability of this work center, use this field to define the variation to the number in the No. of resources field (WSTNBR) that are required for an operation at this particular production resource. For example, if 3 people are defined as needed to operate this (labor) work center but an operator is not available for the defined Capacity variation dates, type in 1.

Tab Replacement

Presentation

You use this section to nominate and prioritize replacement, or alternative work centers. Alternative work centers can be used to carry out operations in a routing should this work center breakdown or a bottleneck occur, for example.

Close

 

Fields

The following fields are present on this tab :

Grid Replacement

  • Alternate work center (field RPLWST)

Type in, or select a suitable work center that can be used instead of this work center should this work center breakdown or a bottleneck occur, for example.

Tab Optimization matrix

Presentation

You use this section to assign an optimization matrix to this work center if you are using the generic Finite scheduleradvanced interface. The Finite scheduler interface provides an integration connector to connect to Sage X3 Web Scheduling or to any web scheduling solution developed by an ISV (independent software vendor) for either cloud or on-premises solutions. The Finite scheduler advance interface is active if the GFSA - Finite scheduler advanced activity code is active.

An optimization matrix links products and attributes defined in setup time matrices to define reduced setup times for products with like products to optimize production. This is particularly useful if your organization produces multiple products using common resources (work centers and machines) and wants to organize the sequence of production so that the setup time between products and operations is minimized. For example, it is more cost effective to spray paint all white colored products, before cleaning the spray system to paint all blue colored products, before then applying a varnish to the paint.

Reminder: An optimization matrix can provide cumulative setup times for each related setup time matrix defined, or provide the setup time matrix with the longest setup time from the list of related matrices.

Attributes and the setup time matrix are only used with your web scheduling solution. They are not used with work orders or Production Scheduler.

Sage X3 Web Scheduling cannot optimize production times when multiple resources are assigned to a work center. This is a limitation of Sage X3 Web Scheduling. As a result the No. of resources field (WSTNBR) in the Management section must be set to 1.
