You can use the CALL FUNCTION statement to call remote functions, just as you would call local function modules. However, you must include an additional DESTINATION clause to define where the function should run:

CALL FUNCTION Remotefunction

DESTINATION Dest

The Remotefunction field can either be a literal or a variable. The field Dest can be either a literal or a variable: its value is a logical destination (for example, "hw1071_53") known to the local SAP System. You can define logical destinations in table RFCDES using transaction SM59, or using the following menu path:  Tools Administration, Administration Network RFC Destinations .
