How to call function module/ class method of another system.

[Former Member]

Suppose now i am working in System A. And i need to check the system Status of System B, System C, System D....

my design is to provide an interface. and each system realize the interface individually.now my question is how cani call the interface, because they are in different systems.

of course i know about the host name, port and logon information over these systems.

who can give my some suggestions or other solutions.

thanks in advance.

Hello,

If u want to call a FM of the other system then that FM should be a RFC enable on one.

<b>CALL FUNCTION func DESTINATION dest.</b>

Effect

Executes the function module from an external source (as a Remote Function Call or RFC); dest can be a literal or a variable.

Depending on the specified destination, the function module is executed in another R/3 or R/2 System. Externally callable function modules must be flagged as such in the Function Builder (of the target system).

Since each destination defines its own program context, further calls to the same or different function modules with the same destination can access the local memory (global data) of these function modules.

To maintain existing destinations, choose Tools -> Administration, Administration -> Network -> RFC destinations

Note

Under certain circumstances, an RFC may trigger a database commit. For this reason, RFCs must not be used between pairs of SQL statements that open and close a database cursor (such as SELECT... ENDSELECT).

Hi Johney,

For a function module, you need to use option "Remote-enabled Module" of Attributes part.

Please read these help links:

Hi,

if you want to call another class in another SAP system you could check the Posting Connector which is able to call function modules and class methods in other SAP systems via RFC destination. It requires some additional customizing and is generic.

As far as I know it also supports a concept to call Function Modules that are not RFC enabled.

Thanks,
Alfred
