Side Information Tables (SAP Library

Side Information Tables

Definition

Side info tables contain information for communication between programs/systems in the form of a sequence of parameters:

Symbolic name of the target system (DEST = Destination)

Following the symbolic name are the connection parameters. The parameters are as follows.

Name of the logical unit (LU) of the partner
Name of the transaction program to be called (TP)
Specific parameters according to constellation and system platform

Side info tables therefore play an important role in connection setup.

For more information refer to Side Info Parameters.

Use

When a program is to communicate with a partner program, the CPI-C interface requires a certain amount of information in order to initialize communication.

As the program should not contain any communication-specific parameters. It is stored as parameter values in one or more configuration files. Information of this type is stored as Side Information outside the application.

The system administrator maintains the parameter values for all CPI-C target system connections in side info tables.

Structure

Side information tables have different names depending on SAP System and platform:

In R/2:	XCOM	(For RFC: Also RFCD)
In R/3:	TXCOM	(For RFC: Maintain TRFCDE via SM59)
OS/2, UNIX, WindowsNT:	sideinfo
BS2000:	SAPGW.DATA.SIDEINFO (SAP Gateway under DCAM)

Integration

Parameter values of the various side info tables take effect according to constellation. For more information on this refer to the section Side Info Table Hierarchy.

This section contains the following topics:

Side Information in R/2 on MVS/VSE Host: XCOM

Side Information in R/2 on BS2000 Host: XCOM

Side Information on OS/2, WindowsNT, UNIX and AS/400 Platforms: Sideinfo

Side Information In R/3: TXCOM
