REMOTE FUNCTION CALL
A Function which is executed in REMOTE SYSTEM (Not in present System)
or
These are Special types of Functions which are used to communicate with remote servers
The remote servers are sap to sap server,
sap to non-sap server.
Functions are of two types.
1.Normal Function :
These are executed in the same system and can't be executed in remote system.
2. Rfc Functions :
These are executed in Remote system.
RFC Functions are Created in SE37 with Option REMOTE ENABLE
In Normal Function We Use Pass By Reference as Importing and Exporting Values.
In RFC Function We Use Pass By Value as Importing and Exporting Values as we need to have Separate Memory in Present System and Remote system.
It Means it uses 2 Memory.
Normal Function are called by Statement CALL FUNCTION 'XXX'.
RFC Functions are Called by Statement CALL FUNCTION 'XXX' DESTINATION 'YYY'.
Here Destination Means The RFC Destination.
RFC DESTINATION
It is a Connection / Link between Two Systems.
SM59 is the Tcode .
Basis Team Create RFC DESTINATION.
We use the DESTINATION in our program while Calling RFC.

EXAMPLE PROGRAM ON RFC:
STEP 1:
At First we will create a RFC
DESTINATION between 800 to 810 Systems.
Basis Team Will Create RFC
DESTINATION in Real Time.
Go to Tcode
SM59.
Select ABAP CONNECTION Folder
and click on CREATE
ICON.
Provide a
name to it and some description as below
Click on TECHNICAL Tab and Select
Target Host As HOST NAME.
Click on LOGON & SECURITY Tab.
Provide LOG
ON Detail as below.
Here we need
to provide 810 Client Details.
Click on Save Button.
We will get
an Information Message as below.
Press Enter.
Click on REMOTE LOGON ICON To Test
it.
When we
clicked on Remote Logon.
We will move
to 810 System.
You can see the 810 System Details at the
Bottom end of the Right side Screen.
Come Back
now.
We will be
in 800 System.
CREATING RFC FUNCTION
Before
creating any Function we need to create a Function Group.
Go to Tcode
SE80 and Select Function And provide a name to it .
Press Enter.
Click on YES
and provide some Description to it as below and Click on SAVE.
Go to Tcode SE37.
Provide a
Name and Click on Create
Icon.
Provide the FUNCTION GROUP Name
and DESCRIPTION.
Go to ATTRIBUTES Tab.
In Processing Type Select The Option REMOTE ENABLED MODULE.
Go to IMPORT tab and provide a
Parameter and select the Check
Box PASS VALUE Means PASS BY VALUE.
Go to EXPORT Tab and Provide a
Parameter and select the Check
Box as PASS VALUE Means Pass By Value.
Go to SOURC CODE Tab and write
the logic.
Save and
Activate IT.
CALLING THE RFC INTO OUR
PROGRAM (SE38).
Go to Tcode SE38.
Create a program.
And call our
RFC function what we
created in SE37.
To Call Our
Function.
Just click
on PATTERN Button.
Select CALL
FUNCTION and give the Function Name.
Click on
Enter.
Provide the DESTINATION NAME What we
created in SM59 Tcode as below.
Here we need
give the inputs from 810 system then it will fetch data from it.
OUTPUT OF 810 System
