Procedure
The list shows all real spool servers in your SAP System as well as any logical servers you have defined. The color-coding in the list indicates the status of each server and whether the server is available for output-processing. For an explanation of the colors, see Interpreting the Spool Server Display.
To create a new definition for a logical server, choose Change and then Create or select a new server and choose Create with reference.
– To classify a server: Choose the appropriate value from Possible entries for the Server class field.
The system will test this value against the classification of devices you assign to this server. It will warn you if the classifications do not match. For example, you will be warned if you try to assign a high-volume printer to a production print server.
– To specify an alternate server: Enter the name of a logical or real server in the Alt server field.
If the server you are defining is inactive or does not have a spool work process, then the SAP System uses this specification to find another spool server to carry out output processing.
– To define a logical server: Select Logical server. Then choose Enter.
In the Mapping field, specify the real or logical server to which this logical server should refer.
The spool system "maps" the logical server name to the server in Mapping. Because this "mapping" is recursive, you can specify either a real server or another logical server.
– To activate load balancing: Select Allow load balancing. Load balancing makes the most sense if you set up logical servers and order your servers in Mapping and/or Alternate server hierarchies.
For help interpreting and manipulating the display, see Interpreting the Spool Server Display.
Result
If you have defined a logical server, you now can enter it as a spool server anywhere in the spool system (in device definitions, for example). Using logical servers in place of or in addition to real servers offers benefits such as load balancing and use of a standardized printing architecture across SAP Systems.
If you have defined a real server, you have assigned attributes to one of your R/3 servers. These attributes, such as a classification or an alternate server, can help you manage your printing architecture and improve reliability.
