1.起因

        为了建立SAP ERP和SAP ME的IDOC传输通道，在SAP ERP一端使用SM59建立TCP连接，在SAP ME的IDOC配置对应程序。然后再SM59测试链接，出现连接错误。后续使用SMGW查看连接情况。闲下来之后，查了下这个TCODE。

2.SMGW

The Gateway Monitor (transaction SMGW) is used for analyzing and administrating the gateway in the SAP system

Path（S/4 HANA）：

Displaying Logged On Clients 

You can display a list of currently logged on systems by choosing [Goto-Logged on systems ] 

 

 通过这里可以查看到，SAP ME已经连接到 SAP ERP，TP Name就是SM59里注册的程序标识。

• LU Name: With CPIC connections via TCP/IP, this field describes the host on which the partner program is running or is to run

• TP Name: Name of the transaction program or the name of the program that was started by the gateway.

• System Type. The following values are permitted:

  • NORMAL_CLIENT: Normal client (external program)

  • LOCAL_R3: Local SAP System

  • REMOTE_GATEWAY: Connection to remote gateway

  • FROM_REMOTE_GATEWAY: Connection from a remote gateway

  • REGISTER_TP: Registered transaction program

• Host Name: Name of host client is running on

• Host address: All TCP/IP names on the host. If there are several network cards then there may be several entries here. Usually 5 alternative host names are supported.

• Last Request: Time of last activity

• Connection Status: Connection status to a client or another gateway at TCP/IP level. The default value is Connection OK.

  In the following cases connections are highlighted in color in the gateway monitor.

  • Connections with status Connection Pending (handshake while opening the connection) are colored orange

  • If the data packets could not be fully written in the network connections, the connection is colored green. If this status lasts for a while, it indicates network problems, or the partner program cannot read any data from the network, because it is busy with other tasks that take time (for example, BRBACKUP).

• Reg. Status: Status of a registered RFC server program. Following statuses are possible:

  • Logged on: The program is logged on, but is not accepting any requests

  • Waiting: The program is waiting for calls from the system

  • Running: The program is processing a request from the system
