Rfc destination

[Former Member]

Hi ,

why do we need rfc destination of type" T" ,in rfc adapter,while creating it?

Thanks

Hi,

TCP/IP Connections (Type T)

Type T destinations are connections to external programs that use the RFC library to receive RFCs. The activation type can be either Start or Registration.

If it is Start, you need to specify the host name and the path name of the program that you want to start.

hi

TCP/IP Connections (Type T)

Type T destinations are connections to external programs that use the RFC API to receive RFCs. The activation type can be either Start or Registration.

If it is Start, you must specify the host name and the pathname of the program to be started.

Activation Type Start

The communication method depends on how you select the program location:

¡ Explicit host

In this case, the program is started either by the default gateway for the system or by the explicitly specified gateway (gwrd) via remote shell.

Ensure that the computer with the gateway process can access the specified computer by entering /etc/ping must be the same as in SM59. (If you call an RFC server program without any parameters, the RfcAccept call always returns an error code (RFC_HANDLE_NULL) and the program terminates at once.)

¡ Application server

On choosing Application server and specifying your program, you can start the program from the SAP application server.

First, ensure that the program can be accessed from the SAP application server and that the SAP application server has the authorization to start the program.

To check this, logon with the user ID of the SAP application server (e.g. c11adm). If possible, change to the working directory of the SAP application server (/usr/sap/.../D.../work) and try to start the RFC server program manually from there. (If you call an RFC server program without any parameters, the RfcAccept call always returns an error code (RFC_HANDLE_NULL) and the program terminates at once.)

¡ Front-end workstation

On choosing Front-end workstation and specifying your program, you can start the program from the SAPGUI.

Ensure that you can access the program with SAPGUI.

Ensure that SAPGUI has the authorization to start the program.

To check this, simply call the RFC server program in your environment.

The function call can also be transactional (CALL FUNCTION... IN BACKGROUND TASK DESTINATION...).

Activation Type Registration

If the activation type is Registration, you have to identify a registered RFC program. With an SAP gateway, an RFC server program can be registered under this ID and then wait for RFC calls from different SAP Systems.

hi,

T is simple of TCP/IP connection.Is that the protocal used to connect the server.

Hi,

we actually use "3" for idoc adapter,why we use "T" for rfc adapter?

Hi Swathi,

TCP/IP: For connecting to Non-SAP systems that does not support the RFC communication.
