I call you and you call me

You you call a function via RFC you need to provide the RFC DESTINATION for the remote system:


CALL FUNCTION ‘ZSNEEZED’
  DESTINATION ’sistema_longe_daqui’.

What if, for some reason, the function running in the remote system needs to call a function in the original system? How would you do it?

It’s simple. SAP helps you. There is a predefined RFC DESTINATION called BACK which represents the original caller system.


FUNCTION ZSNEEZED.
(…)
CALL FUNCTION ‘ZBLESSYOU’
  DESTINATION ‘BACK’.
(…)
ENDFUNCTION.

Automatical.
