RFC Connection using SAP router

[Former Member]

Hi,

I am new to sap basis.

Can any one tell me what is the procedure to create RFC connection b/w two systems using SAP router, and what are prerequisites to create this type of connection.

Thanks in advance,

Make sure the saprouter is allowing traffic for port 33##

It sounds like you are only allowing 32## at the moment

1. = the system number of the system you are trying to connect to (most likely 00)

You will need a line like this in the saprouttab file ->

"P <source host> <dest host> 33##"

Yes Olivier,

I have used the same router string in sm59 and sap logon pad.

but still connection test is failing.

I think problem is b/w source system and SAP router.

can you please tell me what are the possibilities to this connection getting failed.

Hi again,

Very often the saprouter is in a DMZ protected by firewalls.

Check the firewall rules. this is one of the most common problem cause.

Hi Olivier,

Thanks for information.

i am able to logon to that system through SAP logon with

SAP router string as "SAP router string\H\message server"

But its not working to source system.

Kindly let me know how to check the saprouter chain between saplogon and SM59.And how to connect these two.

Hi,

Do you use the same saprouter string in SM59 and in your saplogon ?

That is what I meant by checking yhe chain.

Hi,

Thanks for information,

One more question,

How to check the entries in Route Permission Table.

I created RFC connection b/w two system,

One system is in our domain,other one in custumer domain.

I am able to logon to the system which is in custumer domain.

But RFC connection test is failed.

What is the reason for this,

And how to check whether sap router is connecting or not.

Hi,

How do you logon to the remote system ? With saplogon or with SM59 ?

If by SM59, then the connection test should work.

If by saplogon, then check the saprouter chain between saplogon and SM59.

Hi,

When you create your RFC destination in SM59, you enter the chain of saprouters in the hostname like this :

/H/saprouter1/S/saprouter1port/H/saprouter2/S/saprouter2port/H/hostname

If the saprouter ports are standard (3299), you don't need to put them :

/H/saprouter1/H/saprouter2//H/hostname
