Each system from which you set up a CPI-C communication requires a side information table. Side
information tables can be compared to telephone directories.
This table contains entries with parameters required for communication purposes. The three most

Symbolic destination:
The program setting up a connection uses a symbolic destination which must exist in the side
information table. A symbolic destination can be compared with a name in a telephone directory.
Partner LU:
The partner LU (logical unit) specifies where the communication partner is to be found. It can be
compared with an address in a telephone directory.
Partner program:
The partner program is the program which is started in the partner system or the program to which the
connection is made. It can be compared with the telephone number of the partner.
Side information tables have different names in different systems:
- In R/2, the table is XCOM (maintained with Transaction TM31).
- In R/3, the table is TXCOM (maintained with Transaction SM54 or SM31)
- In external systems, the table is always called sideinfo. Under UNIX, you can maintain sideinfo with
