ABAP Addition ... ID id1 FIELD f1 ... ID idn FIELD fn>
What does it do?Calls the system function cfunc>. A flat character-like data object containing the name of the function can be specified for cfunc>. The function must be entered in the file sapactab.h. Modifying a function or creating a new function requires the ABAP kernel to be compiled again and linked. This requires the C source code files.
Latest notes:If possible, use kernel methods> instead of system functions. External programs should be called using the RFC> mechanism: CALL FUNCTION... DESTINATION> >. With some critical C functions, the system performs an authorization check automatically. If the user does not have the appropriate authorization, a runtime error occurs. The authorization can be checked using the function module AUTHORITY_CHECK_C_FUNCTION>>. The use of the system function SYSTEM>, which can be used to execute operating system statements, is not recommended and can be deactivated using the profile parameter> rdisp/call_system>>. If called, it the function then raises a non-handleable exception. Specifying a system function dynamically is one of the dynamic programming techniques.

What does it do?Passes fields to the called program using pass by reference. ID id1> is used to specify the name of a formal parameter; FIELD f1> is used to specify the associated field from the ABAP> program. If a formal parameter expects an internal table, the latter is passed in the form FIELD tab>.
