The document provides examples of various ABAP 7.x programming concepts including: 1) Variable definition, data types, function modules, and field symbols for looping through internal tables. 2) Different ways to assign values including using VALUE, VALUE #, and methods. 3) Conversions, conditions, switches, and string templates. 4) Pointers, internal tables with various assignment and selection techniques, and reductions. 5) Queries including selections into dynamic variables and tables with unions, cases, and calculations. 6) Object oriented concepts like new, casting, and interfaces.

ev_belnr = DATA(lv_belnr)
ev_gjahr = DATA(lv_gjahr)
ev_bukrs = DATA(lv_bukrs)
).

4. Data
DATA(lv_name) = class=>get_name( lv_kunnr ).

5. Field symbol
LOOP AT gt_itab
ASSIGNING FIELD-SYMBOL(<ls_itab>).
ENDLOOP.

6. Pointer
LOOP AT gt_itab
REFERENCE INTO DATA(lr_itab).
ENDLOOP.

7. Value assignment

8. Value
DATA(ls_kna1) = VALUE kna1(
kunnr = ‘1234567890’
name1 = ‘SAMPLE’
).

9. Value #
DATA ls_kna1 TYPE kna1.
ls_kna1 = VALUE #(
kunnr = ‘1234567890’
name1 = ‘SAMPLE’
).

10. Value # with method
DATA ls_kna1 TYPE kna1.
ls_kna1 = VALUE #(
kunnr = lv_kunnr1
name1 = get_name( kunnr = lv_kunnr1 )
).

11. Conv
check_doc(
iv_xblnr = CONV #( lv_aufnr )
).

12. Cond
get_date_interval(
IMPORTING
!ev_begin = DATA(lv_begin)
!ev_end = DATA(lv_end)
).
DATA(lv_status) = COND char5(
WHEN sy-datum LT lv_begin THEN ‘EARLY’
WHEN sy-datum GT lv_end THEN ‘LATE’
ELSE ‘OK’
).

13. Switch
DATA(lv_status) = SWITCH char10(
sy-msgty
WHEN ‘S’ THEN ‘PERFECT’
WHEN ‘W’ THEN ‘OK’
ELSE ‘ERROR’
).

14. String templates
DATA(lv_string) =
|Today is { sy-datum }| &&
| ,time is { sy-uzeit }| &&
| ,system status: { get_status( ) }|.

15. XSDBOOL
rv_result = XSDBOOL( sy-subrc eq 0 ).

16. Pointer
DATA(lr_ref) = REF #( lv_value ).

17. Internal tables

18. Assign / Index
ASSIGN lt_itab[ 3 ] TO FIELD-SYMBOL(<ls_itab>).

19. Assign / Key
ASSIGN lt_itab[
bukrs = ’1234’
belnr = ‘1234567890’
gjahr = ‘2018’
] TO FIELD-SYMBOL(<ls_itab>).

20. Assign / Hashed key
ASSIGN lt_itab[
KEY primary_key COMPONENTS
bukrs = ’1234’
belnr = ‘1234567890’
gjahr = ‘2018’
] TO FIELD-SYMBOL(<ls_itab>).

21. Reference
DATA(lr_ref) = REF #(
lt_itab[
bukrs = ’1234’
belnr = ‘1234567890’
gjahr = ‘2018’
]
).

22. Default
DATA(lv_name1) = CONV name1_gp(
lt_kna1[ kunnr = lv_kunnr ]-name1
DEFAULT space
).

23. Line check
IF line_exists( lt_itab[ kunnr = lv_kunnr ] ).
" ...
ENDIF.

24. Corresponding
DATA(lt_malzeme) = CORRESPONDING tt_malz( lt_mara ).

25. Corresponding / Mapping / Except
DATA(lt_malzeme) = CORRESPONDING tt_malz(
lt_mara
MAPPING material = matnr
EXCEPT meins
).

26. For
DATA(lt_liste) = VALUE tt_liste(
FOR ls_mara IN lt_mara
WHERE ( mtart EQ ‘ABCD’ )
(
material = ls_mara-matnr
text = ls_mara-maktx
)
).

27. For Groups
DATA(lt_bukrs) = VALUE tt_bukrs(
FOR GROUPS grp OF ls_bkpf IN lt_bkpf
WHERE ( gjahr EQ lv_gjahr )
GROUP BY ls_bkpf-bukrs
( bukrs = grp )
).

28. Reduce
lv_sum = REDUCE #(
INIT x TYPE menge_d
FOR ls_mseg IN lt_mseg
WHERE ( matnr EQ lv_matnr )
NEXT x = x + ls_mseg-menge
).

29. Secondary index
TYPES:
tt_bkpf
TYPE STANDARD TABLE OF bkpf
WITH DEFAULT KEY
WITH UNIQUE HASHED KEY k1 COMPONENTS bukrs belnr gjahr
WITH NON-UNIQUE SORTED KEY k2 COMPONENTS xblnr.

30. Queries

31. Select into dynamic itab
SELECT matnr, mtart, matkl
FROM mara
WHERE matnr IN @s_matnr
INTO TABLE @DATA(lt_mat).

32. Select into dynamic variable
