Add Operations and Subcontract Requirements to Service Revision

This document explains how you link operations to the service revision.

Use this instruction when you want to add new operations or modify existing ones.


One or more operations are linked to the service revision. These can be defined as regular operations or subcontracted operations.

The operations defined in the service revision will be copied to the service record in (MOS300).

These tables are updated:

Before you start

Follow these steps

  1. Start 'Service Revision. Open' (ECS300/B).

  2. Highlight the service revision to which you want to connect new operations and select option 12='Product structure' to display 'Service Revision. Connect Operations and Materials' (ECS312/B).

  3. Select sorting order 1 and panel sequence EFGHI.

    The I panel is used if M3 Scheduling Workbench (SWB) is activated and is not described here.

  4. Specify an operation number and a work center where the work is to be performed. Select New to display the G panel.

    A sequence number must not be specified, as this is used for material lines only.

    It is good practice to sequence the operation numbers in a way that allows new sequence numbers between old ones. Example: 10, 20, 30, etc.

    The work center can be defined either as a regular work center or as a subcontract work center. Work centers are classified as subcontract work centers in 'Work Center. Open' (PDS010).

  5. Enter a sub-service if one is to be created.

    Sub-services are used for network planning. If you enter a sub-service ID here, a sub-service record is created in (ECS300). It is then possible to connect specific requirements to the current operation, which will be the same as the sub-service record.

  6. Specify a brief operation description, the run time and the setup time for the operation.

    Setup times are optional fields and indicate the amount of time required to prepare the maintenance object before work can begin.

  7. Specify the planned number of workers that are required for the job and, if required, the number of workers needed to set up the operation.

  8. Specify how the operation is to be processed if it belongs to a phantom routing (optional).

  9. Specify a scrap percentage and a scrap setup, a document ID and a tool number (optional fields).

    Scrap percentage is normally used for manufacturing to indicate the expected scrap in the operation.

  10. Specify a tool number and a subcontract control, if this is a subcontracted operation. Press Enter to display the H panel.

    The subcontract control determines how and when purchase requisitions and purchase orders are created.

    If blank is selected, no purchase order or requisition is created. The purchase order must be manually created.

    If 1 is selected, a requisition order for linked material lines and a purchase order are created. The requisition is created in (MMS100) when the planned PO is released.

    If 2 is selected, only a requisition for linked material lines is created in (MMS100). It is created when the planned WO is released.

  11. Enter a labor skill code and an operation description (optional fields), and specify whether this operation is an assembly operation. Press Enter to display the I panel.

    If this operation is defined as an assembly operation, there will be a warning if suborders have a finish date that is later than the start date on this operation. The warning is issued in (MOS110).

  12. Press Enter to finish.
