Create Systems 
You create systems to be able to use them in Solution Manager projects.
The system determines the displayed data automatically for ABAP-based SAP products, if you have setup automatic data capture for the system landscape. You can enhance this data or switch the data source to manual maintenance.
For non-ABAP-based SAP products, and non-SAP-products, you must create systems yourself, to use them in your solution landscape in operational processing.
You are in the Solution Manager System Landscape transaction (SMSY).

You can also create systems under the guidance of assistants. To call the assistant, select the landscape component Systems, and choose Create New System with Assistants, in the context menu.
...
1. Select the landscape component Systems, and choose Create New System, in the context menu.
2. Enter the system ID as the system name, in the following dialog box. If there are other systems with the same name in your system landscape, enhance the system names, to distinguish them, e.g. system AAA_1 and system AAA_2.
3. Choose a product and a product version from the possible entries help.
4. Save your entries.
The Solution Manager displays the relevant main instances below the system, in the overview tree. For a new system, the Solution Manager derives the relevant main instance from the selected product.
5. Select the system, and you can flag another ABAP-based main instance as Relevant or Also Installed, or set the Relevant flag for several non-ABAP main instances, in the Main Instance Selection tab.

· Only relevant main instances can be displayed in operational processing in your solution landscape.
· You can only assign system components to the relevant main instances.
· You cannot delete the Relevant flag if the system is used in a logical component, to avoid inconsistencies in the solution landscape.
6. You can assign system components to the relevant main instance, e.g. an ITS, in the Main Instances Selection tab:
i. Set the System Component Assignment flag for the relevant main instances.
ii. Choose the system component from the possible entries help
iii. You can create new system components with Create System Component.
7. You can specify further information about the system.
You can flag a system as Planned or Productive. You can, for example, reset the Production flag for a copy of a production system in a backup system landscape.
8. Save your entries.

There must be one relevant ABAP main instance per system for ABAP-based SAP products.
If there are more than one ABAP main instances for this product, one ABAP main instance is automatically flagged as Relevant when the system is created. You can:
· change this automatic selection, and flag another ABAB main instance as Relevant.
· to be able to put several ABAP main instances in a logical component for a system, and use it in projects and solutions, flag the ABAP main instances as Also Installed.
The system copies the selected main instances into the left-hand screen area.
...
1. Select the ABAP main instance in the left-hand screen area below the system to be defined, and enter the installation number in the Header Data tab. Entry of the remaining data is optional.
2. Specify the system number and the message server in the Header Data tab, to be able to generate RFC connections for this system.
3. Create the clients for the selected main instance, in the Clients tab.
4. Enter a client number.
5. You can enter a name for the client.
6. You can choose a role from the possible entries help.
7. Specify a logical system.
8. Save your entries.
9. There are two ways of getting RFC connections for clients:
¡ Assign existing RFC connections to the client:
i. Choose a client in the Clients tab.
ii. Choose Assign and Check RFC Destinations.
iii. Choose an existing RFC connection from the possible entries help for the RFC connection types.
iv. Set the Assign RFC Dest. For System Monitoring flag, to reuse the RFC destinations in this client for central system monitoring. You only need to assign this flag for one client per system.
v. Save your selection.
¡ Generate the RFC connections again for the clients.

You cannot generate RFC connections for Planned systems.
You can also perform this step later.
10. You can specify the instances in the Instances tab. The possible entries help contains the servers which you defined previously in the landscape component Server.
11. You can display details of the installed software components, and specify/change their Support Package status, in the Software Components tab.
12. Save your entries.

If there is a read RFC connection for at least one client, you can refresh the system data with the Read System Data Remote pushbutton. The SAP Solution Manager requires up-to-date system data, to be able to read, e.g. information about imported Support Packages. You can set-up automatic system data refresh when you Generate the RFC Connection.
...
1. Select the system for which you want to specify main instances, and set the Relevant flag for the relevant main instances, in the Main Instance Selection tab.
The system copies the selected main instances into the left-hand screen area, under the system.
2. Select the main instance and enter the required data at the right-hand side of the screen.
3. Save your entries.
