ALV에서 레이아웃 저장, 관리 기능만 추가하고 싶다면

1. Variant 변수를 선언하고,

DATA: GS_VARI TYPE DISVARIANT.

2. ALV Display전에

  GS_VARI = VALUE DISVARIANT(
                  REPORT   = SY-REPID
                  USERNAME  = SY-UNAME
          ).

3. ALV Display 할때
   IS_VARIANT, I_SAVE = 'A'

  GO_GRID->SET_TABLE_FOR_FIRST_DISPLAY(
    EXPORTING
      I_BYPASSING_BUFFER            = ABAP_TRUE
      IS_VARIANT                    = GS_VARI
      IS_LAYOUT                     = GS_LAYO
      IT_TOOLBAR_EXCLUDING          = GT_FUNCTIONS
      I_SAVE                        = GC_A
    CHANGING
      IT_OUTTAB                     = GT_LIST
      IT_FIELDCATALOG               = GT_FCAT
    EXCEPTIONS
      INVALID_PARAMETER_COMBINATION = 1                " Wrong Parameter
      PROGRAM_ERROR                 = 2                " Program Errors
      TOO_MANY_LINES                = 3                " Too many Rows in Ready for Input Grid
      OTHERS                        = 4
  ).
