Error in RFC - SMSY

[Former Member]

Hi,

Am creating RFC from SMSY. When i run thru the wizard for RFC generation wizard, i provide below option,

1.Selected Customizing Distribution & Change Request Management and Trusted System RFC connection.

2.Generate User And Password : SOLMAN<SID><CLNT> and SOLTMW<SID><CLNT>

3.Generate Incoming RFC Connection : Generate User And Password : SOLMAN<SID>

4.Assign RFC Connection for SYstem monitoring

Upon Creating RFC, system throws below error.

RFC destination SM_<SID><CLNT>_READ creation error. RFC destination may have errors

RFC destination SM_<SID><CLNT>_READ generation error

RFC destination SM_<SID><CLNT>_TRUSTED creation error. RFC destination may have errors

RFC destination SM_<SID><CLNT>_TRUSTED generation error

RFC destination SM_<SID><CLNT>_TMW creation error. RFC destination may have errors

RFC destination SM_<SID><CLNT>0_TMW generation error

Destination 'SM_<SID><CLNT>_TRUSTED' is used to generate destination 'SM_<SID><CLNT>_BACK'

RFC destination SM_<SID><CLNT>_BACK generation error

RFC error(SM_<SID><CLNT>_READ): Error when opening an RFC connection

When i go to the Read RFC and try to test the Connection, system throws below error.

Hi Mohammed,

Check below points,

1:The user through which you are running this setup has S_RFC* object authorization in both solman system and satellite system

2:Create a new RFC connection manually between Solman and Satellite system to see whether it works fine or not

3:Enter the solman hostname in the hostfile of satellite and viceversa.

If the connection again failed check with what RC it failed ex:0,1

Let us know the results

Regards

Hi,

The issue here is with the hostname which you provided for the RFC connection, you had given "'HOSTNAME'" for the hostname field, is that correct?

Go to Tcode SM59 and expand the ABAP connections and select the RFC destination which is having the error and correct the hostname entry, you can also provide the IP adress inspite of hostname..

Hi Sam,

I should not provide the host name manually because i generate the RFC thru' the Wizard.

But at the end of the RFC generation, i receive error. And then i manually goto SM59 and open the created RFC (with errors) and try to test connection. Then it throws the below error.

Hope there is an issue with the HOSTNAME. How to check the HOST NAME and how is the system picking the HOSTNAME while creating the RFC? Does it picks the Hostname or FQHN ?

Pls provide me your valuable comments.

Hi,

HOSTNAME should be the hostname of the SAP system you want to connect, you need to know this if you want to create the RFC connection.As mentioned before you can also use IP address inspite of hostname.
