RFC Destination of TCP/IP type :: Using Explicit Host Option

[Former Member]

Hi

We need to call the executable file in an External non-sap system.

We created the RFC detination for this & follow below steps -->

*) Create RFC Destination of type TCP/IP

*) Select option " <i>Start Explicit Host</i> "

*) In Program parameter provide the path & name of the executable file e.g c:\windows\notepad.exe

*) In Target Host providing the name of non-sap system.

But while using Test Connection we are getting following error -->

<b>ERROR timeout during allocate

LOCATION SAP-Gateway on host clxstst02 / sapgw00

DETAIL no connect of TP net from host CLWBRIDGE after 22 sec

COMPONENT SAP-Gateway

COUNTER 34

MODULE gwr3cpic.c

LINE 1785

RETURN CODE 242

SUBRC 0

RELEASE 640

TIME Thu Dec 14 15:28:33 2006

VERSION 2</b>

Pls. suggest what needs to be done.

Hi lalit,

Looks like a firewall issue.Ensure firewalls are opened from both the ends as well entires are made in host files.

After that do the testing again.

Please award points for useful answers.

There are no firewall's between the R3 servers and the PC, we are trying to connect. Both of them are in same WAN.

Can you pls. more specifc that what entries we need to make in host files. I asked our systems team here & they use DNS rather than host files & asking what we need in host files.

Hello Lalit,

Even though DNS is used you may have to have entires in host file.

Suppose the SAP server is A and the PC is B.

The the hostname/IP address for B should be maintained in A and vice versa should also happen.

Also check if you are able to ping the PC from the SAP servers and vice versa.
