Dump, because RFC connection failed

Private_Member_19084 — Fri, 09 Sep 2011 05:41:43 GMT

Hi experts,

we have a few Z-FMs which read the data from another system via RFC.

So the FM are created in the target system and we call them from our productive system.

These FMs are implemented in many programs.

Our problem is, when the target-system is not reachable (downtime, error, ...) all programs get a dump, because the rfc connection failed.

How can we avoid this dumps? (the programs should also be executable without the FM-data)

Is there a badi or exit for RFC-connections?

thx in advance

Hi Christian,

This is right if there is no response form the rfc.This RFC are you using to get data or to send data.Are you maintaining exceptions handling.

Madhu.

Hello

How can we avoid this dumps? (the programs should also be executable without the FM-data)

SAP has defined three [RFC exceptions|http://help.sap.com/abapdocu_702/en/abenrfc_exception.htm]: system_failure, communication_failure & resource_failure.

You'll need to implement them in your RFC to prevent the dumps.

Hi,

Before your calling your Z-Fm fountion Module you have to call RFC_PING funtion module pass the respective destination name . if sy-subrc = 0 . call your z fuction module.

lv_rfc_dest = " your destiantion

CALL FUNCTION 'RFC_PING'

DESTINATION lv_rfc_dest

EXCEPTIONS

communication_failure = 1

system_failure = 2

OTHERS = 3.

if sy-subrc =0 .

call z_fm """" call your z function module

endif.

Hi Christian,

The RFC_PING as suggested by Abdul will only check for the availability of the Remote System, the chances are that even though the target system is available it might be short on resources or there could be an exception at the application level.

I would suggest you go ahead with Suhas' suggestion of handling the exceptions while calling your ZRFC.

Chen

Many thx for so many answers!

I decided to try the solution with the exception and it runs perfect!

I'm sorry, that I've not read that F1-Help first to statement DESTINATION, because there the exceptions also explained!

Thank you again
