TCP/IP RFC ERROR - Msg DGW 748 not found

[Former Member]

Hi Experts ,

I have installed a new Enterprise portal system and try to establish connection with an existing SRM ABAP stack .

1) I have created Jco RFC with rfc destination to SRM - Both destination ping and JCo RFC Status are fine

2)Created a TCP IP RFC from SRM system to portal using the registered program .

3)gw/acl_mode is set to 0

Yet i am getting the following error during connection test , Please let me know whether any changes are required in Java stack or anything that could resolve this issue .

Logon	Connection Error
Error Details	Error when opening an RFC connection (CPIC-CALL: 'ThSAPOCMINIT' : cmRc=19 thRc=7

Hi Isaias,

Thanks for the reply.I have referred the notes and set  gw/acl_mode to 0 ,however its not working . I have also tried with gw/acl_mode to 1 and permitted all the connections in secinfo & reginfo files , yet the same error occurs .

Any other suggestions please.

Thanks & Regards,

Deepak.

Hello Deepak,

Did you set "gw/acl_mode = 0" at the gateway where the program is being registered?

This would be the gateway indicated at the "gateway options" of the SM59 destination.

If the "gateway options" are blank, the parameter has to be set on all instances of the SAP system where the destination exists.

In addition, if you changed the parameter dynamically (e.g., transaction RZ11), you have to de-register and re-register the program (as informed at the WIKI, when it talks about changes to the reginfo file).

Hello,

Per the SAP note 63347, the return code 748 means "access to registered program denied".

Check out the SAP KBA 1850230. It has a video illustrating how the reginfo rules work.

You can also read this WIKI page for more detailed information about the Gateway security features.
