This error comes when your external program is not registered to SAP Gateway. Please check the corresponding RFC, it will not be working.

Refer Sap Note 353597

Hello,

ERROR 679 means

TP_NOTREGISTERED              679 TP not registered

it indicate you have T type RFC, it point to a external program and this program did not register on the

gateway, just need to register it as per note 353597.

Please note, RFCEXEC is just a sample program, you need to register your "real" program on your gateway.

Hi,

Increase Gateway timeout parameter..

The Parameter is " gw/cpic_timeout "

Change this parameter from the following path..

MGW > Goto >Parameters>Change/Display.

Change this parameter for each application server because it is dynamic and server specific.
