CALL METHOD - dynamic_meth

Syntax

... (meth_name)
  | cref->(meth_name)
  | iref->(meth_name)
  | (class_name)=>(meth_name)
  | class=>(meth_name)
  | (class_name)=>meth ... .

Alternatives:

1. ... (meth_name) ... .

2. ... cref->(meth_name) ... .

3. ... iref->(meth_name) ... .

4. ... (class_name)=>(meth_name) ... .

5. ... class=>(meth_name) ... .

6. ... (class_name)=>meth ... .

Effect

: These names are used to dynamically specify methods. For meth_name and class_name, character-type fields are expected, which must contain the name of a method or a class in upper case during the execution of the statement.

Alternative 1

... (meth_name) ... .

Effect

: This form is only possible for methods of the same class

Alternative 2

... cref->(meth_name) ... .

Effect

: This form is possible for all visible methods of objects. cref can be any class reference variable that points to an object that contains the method specified in meth_name.

Alternative 3

... iref->(meth_name) ... .

Effect

: This form is possible for all visible interface methods of objects. iref can be any interface reference variable that points to an object that contains the interface method specified in meth_name.

Note

In contrast to access using class reference variables, interface reference variables can only be used to access interface components, and not to access all components, even with dynamic access.

Alternative 4

... (class_name)=>(meth_name) ... .

Alternative 5

... class=>(meth_name) ... .

Alternative 6

... (class_name)=>meth ... .

Effect

: These forms are possible for all visible static methods. Both the class and method can be dynamically specified. The class class and the method meth can also be specified directly.

  CLEAR  :  gt_row_no,  gt_row_no[].

  CALL METHOD  grf_grid_0101_1->get_selected_rows
    IMPORTING
      et_row_no  =  gt_row_no.

를 예로 들면 다이나믹도 좋은데요. 그냥 perform 쓰시면 될 것 같네요.

ex) perform 예.

perform get_selected_rows changing grf_grid_0101_1

                                                     gt_row_no.

form get_selected_rows changing cl_grid type ref to cl_gui_alv_grid

                                                ct_row_no   type table.

  clear ct_row_no.

  CALL METHOD  cl_grid->get_selected_rows
    IMPORTING
      et_row_no  =  ct_row_no.

endform.

dynamic 보다는 그냥 편하게 perform 으로 대상 매개변수만 바꾸시는 것이

보시기도 편하고 사용도 그리 어렵지 않아 좋을 것 같습니다. ^^
