  System Switch

Purpose

If you set up a distributed system landscape to perform operations or exercises, you have to define the relevant operational system for the force elements of the operational structure or exercise target. You can switch the operational system for force elements during routine operation if the logistical processes for these elements are to be performed from a specific point in time by a system other than the system that is currently defined.

It may be necessary or useful to carry out a system switch in the following cases:

  • Setting up a decentralized system

    If you have defined this initially as the operational system when setting up an operational structure or exercise target in the central system, you can switch a system while setting up the relevant decentralized system by defining this decentralized system as the new operational system.

  • Organizational changes in routine operation

    • Changes to the operational structure/exercise target in the central system may result in operational responsibility for a force element switching from one decentralized system to another.

    • A system switch may be useful for central or decentralized task organization between force elements with different operational systems.

  • Dismantling a decentralized system or delimiting force elements

    In this case, you can define the central system as the operational system for force elements concerned in order to perform final work in the system.

For more information about switching a system, see System Switch Execution .

Prerequisites

You have assigned an operational system to the operational/exercise force elements initially .

Data exists in the target system for the force elements that are to switch systems.

Process Flow

Steps in the issuing (that is, currently operational) system:

  1. You plan the system switch for a force element.

  2. You trigger the system switch.

  3. The system starts a workflow to initiate preparatory measures.

    Note Note

    In the issuing system, the issuing system has In Transition status and the receiving system has Planned System status. In the receiving system, the issuing system still has Active System status.

    End of the note.

  4. The workflow triggers various subarea workflows in an order specified by you.

    1. The recipients of the workflow work items make the required preparatory measures in the business subareas and complete the work items.

    2. You can perform checks in the issuing system for each business subarea to determine whether the force element can be switched and to monitor the status of the work items.

  5. To complete the preparatory measures, the issuing system triggers the final actions in the receiving system for each workflow .

    Note Note

    In the issuing system, the issuing system still has In Transition status and the receiving system has Planned System status. In the receiving system, the receiving system now has Active System status.

    End of the note.

Steps in the receiving (that is, new operational) system:

  1. The workflow triggers various subarea workflows in an order specified by you to initiate final actions.

    1. The recipients of the workflow work items perform the required final actions in the business subareas and complete the work items.

    2. You can perform checks in the receiving system for each business subarea to determine whether the force element can be switched and to monitor the status of the work items.

  2. You are prompted by the workflow to send an IDoc from the receiving system to identify the receiving system as the new operational system for the force element concerned in the issuing system.

    Note Note

    In the issuing system, the issuing system now has Former System status. The receiving system now has Active System status in both systems.

    End of the note.
Subsequent Processes

  • During the switching process, the system informs all systems in your system landscape of which systems are acting as the operational systems for which force elements. For more information, see Informing Systems of System Switch .

  • During a system switch, it may be necessary to change the assignment of mobile devices involved. For more information, see the documentation for SAP Mobile Defense & Security .
