CALL - Call a System Function:

Note

This statement is for internal use only.

It cannot be used in application programs.

Note

As of Release 6.20, you should use Kernel Methods instead of system functions.

Syntax

CALL cfunc.

Addition:

... ID id1 FIELD f1 ... ID idn FIELD fn

Effect

Calls the system function cfunc. The relevant function must exist in the file sapactab.h. If you change or recreate a function, you have to compile and link the SAP kernel again. For this, you need the C source code files.

Normally, external programs should be called by RFC with CALL FUNCTION ... DESTINATION.

Addition

... ID id1 FIELD f1 ... ID idn FIELD fn

Effect

Passes fields to the called program by reference. With "ID id1", you specify the name of a formal parameter, and with "FIELD f1" the relevant field from the ABAP/4 program. If a formal parameter expects an internal table, the latter is passed in the form "FIELD tab[]".

Example

DATA RESULT(8).

CALL 'MULTIPLY' ID 'P1' FIELD '9999'

ID 'P2' FIELD '9999'

ID 'RES' FIELD RESULT.

Note

With some critical C functions, the system automatically performs an authorization check. If the user does not have the appropriate authorization, a runtime error occurs. You can check the authorization with the function module AUTHORITY_CHECK_C_FUNCTION.
