How to use user defined types in ALV- Factory method
In traditional ALV, the field catalogue must be created before calling the REUSE_ALV_GRID_DISPLAY. In ALV OOPS using Factory method the field catalogue is not required. Check the example below
We have created a structure with some
fields from BKPF and an internal table with the structure created.
We have created instance for ALV using the
internal table without creating the field catalogue and calling display method
to display ALV output.
The ALV created using Object oriented
method is very simple when compared to traditional ALV. Also, it is reusable
and improves performance.
You can also use new open SQL syntax using
@DATA to create the internal table type.

REPORT ztest_alv.
TYPES: BEGIN OF ty_bkpf,
bukrs TYPE bukrs,
belnr TYPE belnr_d,
gjahr TYPE gjahr,
xblnr TYPE xblnr1,
END OF ty_bkpf.
DATA: it_bkpf TYPE TABLE OF ty_bkpf.
DATA: lo_alv TYPE REF TO cl_salv_table.
START-OF-SELECTION.
SELECT bukrs belnr gjahr xblnr
FROM bkpf
INTO TABLE it_bkpf
UP TO 10 ROWS.
IF sy-subrc IS INITIAL.
cl_salv_table=>factory(
IMPORTING
r_salv_table = lo_alv
CHANGING
t_table = it_bkpf[]
).
lo_alv->display( ).
ENDIF.
