Getting error message RFC_ERROR_COMMUNICATION

[raskhan_thajudeen]

Hi Friends,

We were trying to post some journals from excell sheet to SAP.

the macro programming were done and all set.

but we were getting the below error when the excell tries to get connect to SAP instance through SNC logon .

And this error we are getting only in one client of the SAP instance.For the rest of the clients its working..and we are able to login directly through saplogon pad through SNC.

Can anybody know why this is happening.No changes were made in the SAP instance.

the error message is as follows.

Hi

can you please check your server file in System32/drivers/etc?

There should be an entry for sapgwXX 33XX/tcp

sapdpXX 32XX/tcp

where XX= your system number

Thanks and Regards

Hi Anindya,

Thank you for your message.

We are using Unix servers. I think what you have mentioned is for windows severs?...

Hi raskhan

You will have services file for Unix too.. Just check in \etc\services. It depends on your system, just find that services file.

Thanks and Regards
