Work center is an organization unit where manufacturing activities are performed.

In other words, Work Centers are the master data which represent real machines, Production Lines, Assembly Work Center, etc. Manufacturing activity or Operations are carried out at Work Center.

  • Work Centers are used in task list (routing) operations and is copied to production orders or process orders for the shop floor planning and execution.
  • Work Center data is used for

  1. Scheduling

    When a production order is created, the duration of an operation can be calculated based on operating times in routing and formulas which are entered in the Work Center.

  2. Costing

    The costs of an operation can be calculated in the production Order based on the formulas which are entered in the Work Center. Work Center is also linked to a cost center.

  3. Capacity Planning

    The available capacity and formulas for calculating capacity requirements are stored in the Work Center.

  • Work Centers are used in routing operation data.
  • Work Center is created for a manufacturing plant and is identified by a code.
  • Group of similar machines can also be created as a single Work Center. For example, 5 similar machines can be created as 1 Work Center with a number of capacities as 5.
