Hi,

I created a simple RFC FM and called from report program with a valid destination to XI system.

the only parameters i am passing is tables ITAB to XI.

But it is going in Synchronous mode to XI.. but i want in Asynchronous RFC...

Any idea how to achieve this?

CALL FUNCTION 'ZTEST_RFC' DESTINATION 'SAPXI'

TABLES

T_TAB = ITAB.

how can i change this to Asynchronous RFC?

Hello,

You need to put IN BACKGROUND MODE at the call function command.

Hi,

Use IN BACKGORND TASK.

CALL FUNCTION 'ZTEST_RFC' DESTINATION 'SAPXI'

IN BACKGOURND TASK

TABLES

T_TAB = ITAB.

Any error, you can check in the transaction SM58.

The task just has to be a valid input. you dont need to declare anything. You have to add one more form to receive results inside which you will use RECEIVE RESULTS FROM FUNCTION 'your_function_name '

I GOT SHORT DUMP..

Exception condition "COMMUNICATION_FAILURE" raised.

A RAISE statement in the program "ZGIRI" raised the exception

condition "COMMUNICATION_FAILURE".

Since the exception was not intercepted by a superior

program, processing was terminated.

EXCEPTIONS

Hi,

Have you check the RFC destination SM59 connection ( Test Connection) ?

Looks like problems with XI.

In the XI, is the communication channel is OK?

Regards,

Fernando

Re: RFC

Former Member — Fri, 02 May 2008 19:26:11 GMT

If commnication channel is not setup correctly then why only 1 field values pass to XI?

i mean itab emp no: and emp name there

1 abc

2 xyz

3 dsf

in xi it is showing like

no values for emp name.

pls help on this issue..
