Communication in a BS2000 Host Environment (SAP Library - SAP Communication: CPI-C Programming (BC-CST-GW))

Communication in a BS2000 Host Environment

Definition

As in the SNA world, a session between two network users is used as a medium for data interchange.

In a BS2000 environment, program-to-program communication is possible with the following constellations:

UTM on both partner systems

A conversation between two programs is based on UTM-D.

DCAM with the SAP Gateway on the BS2000 host

In addition to an R/3 System, any external system can communicate with the R/2 System via the SAP Gateway and DCAM, providing the following requirements are met:

TCP/IP support
SAP communication interfaces (function libraries cpictlib or librfc)

The SAP Gateway allows communication both with an UTM R/2 System and with a DCAM R/2 System.

For information on hardware and software supported, refer to the following brochure: SAP - Supported Network Products.

Detailed documentation on the SAP Gateway for BS2000 is supplied with the gateway, in the SAPGW.README file.
