Logical System Levels

The system landscape supported by the Defense Forces & Public Security and SAP Mobile Defense & Security components is divided into two logical system levels:

Central level

This level includes all the systems that you use to perform the following tasks:

Execution of business processes in the domestic base of your organization

Central setting upanddismantling of systems for performing operations and exercises

Central administration of the entire system landscape (domestic base, operations, and exercises)

The respective development and quality assurance systems required are also included in addition to the production systems.

Decentralized level

This level includes all the systems that you operate productively for executing business processes for operations and exercise outside of the central level.

This also includes each system specifically set up within these production systems for quality assurance or similar tasks.

The logical distinction between the central and decentralized levels does not determine the physical location of each system. This means that the systems at decentralized level can exist at the same location as the systems at central level.

Central System Level

The central level of the system architecture includes the following systems:

Central System (Production System)

The central system includes at least one ERP system at your organization’s location. It comprises the complete range of business functions for supporting processes in the domestic base and during operations and exercises.

The system unit described here as the centralized system can also consist of several systems. In this way, for example, you can set up additional ERP systems or separate systems for operating a Knowledge Warehouse , Business Warehouse , or other SAP solutions.

You usually set up a separate system for running Central User Administration (CUA) .

Template and Administration Systems

Solution Manager system

The Solution Manager system contains the SAP Solution Manager functions for setting up, managing, and dismantling all systems involved in the system group.

Template System for Decentralized Systems

The template system for setting up decentralized systems is a copy of the ERP system from the central system level. It comprises the functions from the Defense Forces & Public Security component.

This template system is copied to set up decentralized systems.

Template System for Middleware Systems

An additional template system is used as a copy template for setting up central and decentralized middleware systems as well as the associated installation toolkit servers.

Decentralized System Level

During an operation, you can operate multiple instances of the decentralized system level, each comprising a decentralized system, a middleware system, and multiple mobile devices. In this way, every operation and exercise (individual operation and exercise forces) can be controlled using separate decentralized systems.

Production Systems

Decentralized Systems

The decentralized systems are located in the area of operation and contain the data and functions that are required for a particular part of a process.

Every decentralized system has at least one ERP system. Similar to the central system, the level described here as the “decentralized system” can also comprise multiple SAP systems.

Middleware Systems

Each decentralized system is assigned a middleware system (including an installation toolkit server) for operating mobile applications on mobile devices.

Middleware systems and installation toolkit servers can be run on shared or separate hardware.

Mobile Devices

Mobile devices, connected by means of the middleware systems to the respective decentralized ERP systems, enable the mobile applications from the Defense Forces & Public Security component to be used. The mobile devices contain the data and functions required for the particular part of the process for which they are to be used.

They can also be connected directly to the central ERP system by means of a suitable middleware system.

Logistics Execution Systems (LES)

Decentralized LES systems can be assigned to a decentralized ERP system so that decentralized and, if necessary, offline Warehouse Management functions can be used. An LES is assigned to exactly one ERP system.

External Systems

Decentralized systems can be connected to external systems, such as geographical information systems (GIS) or national/multinational command and control systems.

Mirror Systems

For each software version that is used in the decentralized and middleware systems, a mirror system is generated to enable the importing and testing of software logistical transports for the productive decentralized systems. A mirror system can thus represent several production systems.

For more information about setting up, operating, and dismantling the system group, see the description of the operational scenario .

The figure shows an example of communication between systems with administration and quality assurance functions for one of three independent system landscape operations.
