Determine if called as RFC

[Former Member]

Anyone know of a way that I can programmatically determine within a function module if it has been called as an RFC or not ?

Have looked at SY variables but doesn't seem to be one.

TIA

Hi,

If the function module exists in table TFDIR with mode set as Remote(fmode field = R) ,then it can be called as an RFC.

Hope this helps.

Thanks.

Hi Philip,

If any FM is called as an RFC it needs a Destination (remote Client).

So if your FM is a RFC only, then you provide the destination detail which you already know. Otherwise its a normal one.

Hope this helps you to some extent.

Hi Philip,

first in the attributes of a function module u can see,whther the function module is RFC enabled or NORMAL.if the radio button is checked for RFC then its a RFC FM.Also the RFC FM needs the destination .

for example..

CALL FUNCTION <FUNCTION MODULE NAME> DESTINATION 'DESTINATION NAME'.

If it is called like this ,then it is AN RFC enabled FM.

Hoping ithelps u.

Thanks for your replies so far but maybe I need to rephrase the question.

I understand that in the attributes of a function mod. you can set it as rfc or normal. Though if it is flagged as rfc it can actually be called normally as well.

I want to be able to write some abap code within my function module that will tell me whether it has been called as a RFC or as a normal call.

Thanks again

Simple option is keep a export parameter System_id as optional . While calling the FM pass the SY-SYSID to it. Inside the FM check

if system_id = sy-sysid.

*Then it is not called with any RFC destination

Else.

*Then sy-sysid will return the destination system so

system_id will not be equal to sy-sysid.
