STMS: RFC error: Error when opening an RFC connection

[Former Member]

Hello ,

I was wondering if you could help me with this TMS issue.

The transport system is not working properly.

The fallowing error is shown:

Could not start transport control program tp

RFC error: Error when opening an RFC connection

There was an attempt to start the transport control program tp using the local RFC interface. An error occurred here.

Error code: 3

RFC error text: Error when opening an RFC connection

Meaning of the error codes:

03 RFC system failure

04 RFC communication failure

System Response

The function terminates. Details about the error can be found in the trace file of the Gateway Monitor (SMGW).

Procedure

Contact your system administrator or use report RSTPTEST to localize the error. You can then execute the command again.

When I test the tp tools:

tp Call and RFC Ping: Error when opening an RFC connection

Another thing would be that when testing the RFC connection CALLTP_Linux I have the error:

ERROR: user XXX is not authorized to start TP /usr/sap/SID/DVEBMGS53/exe

And I have to say that the user has maximum authorizations.

I also checked the permissions of the tp at OS level but everything seems to be ok.

Can you help me with this?

BR,

Hi,

what does the tp system log says?

check that the services are populated on the services file?... or that the port is not blocked by the firewall?

try upgrade of your TP and R3Trans and see if it helps.

Thanks,

Dear Manoliv,

first check host entries available in source and traget system (/etc/hosts), if not please enter the vales and bulid the RFC connection using hostname, it will work.

Dear Manoliv,

Firstly please check if you have enough space in /usr/sap/trans file system.

If OK, please run RSTPTEST report from SE38 and check the log file in SMGW => Goto => Trace => Gateways => Display file

and paste the log here.

Also, I assume filesystem permissions are OK.

Regards,

Sujit.

Hi,

Go to STMS in your system and go to System routes. By Selecting the each system ensure you are able to reach it by doing the connection test in connection tab.

Also ensure your configuration is showing in the Green Symbol, else check for that as well

Hi

Check once TMSADM user is locked or not.

If this issue continues on SMGW check for logged on clients in error if they are for TMS RFC just delete those entries and check whether the trusted TMS RFC works fine.

If not you may have to recreate the whole TMS.

Run RSTPTEST report (in SE38) & check the error
