For more details, refer to the following section Configuration for a TCP/IP Connection (section "BS2000 Host Systems").

Process flow

The process is as follows:

  1. The R/2 ABAP program starts the job SAPGWHO (communication program gwhost). The job SAPGWHO identifies the appropriate entry in the side info file SAPGW.DATA.SIDEINFO via the R/2 table XCOM.
  2. The job SAPGWHO sets up the connection to an SAP Gateway on a UNIX computer (not under BS2000). In the course of this, the SAP Gateway is identified via the side info file.
  3. The SAP Gateway starts the actual target program.
