[su_box title=”1. Inline Declarations” style=”soft” box_color=”#f0ab00″]Now you can declare the variables and field-symbols at the same position where you are using them. Inline declarations are possible only for DATA and FIELD-SYMBOL.
DATA lv_name TYPE string. lv_name = 'SAPLEARNERS.COM'.
DATA(lv_name) = 'SAPLEARNERS.COM'.
DATA: lw_mara TYPE ty_mara, LOOP AT lt_mara INTO lw_mara. WRITE: lw_mara-matnr,lw_mara-ernam. .... ENDLOOP.
LOOP AT lt_mara INTO DATA(lw_mara). WRITE: lw_mara-matnr,lw_mara-ernam. .... ENDLOOP.
DATA: lw_mara TYPE ty_mara. READ TABLE lt_mara INTO lw_mara INDEX 1.
READ TABLE lt_mara INTO DATA(lw_mara) INDEX 1.
TYPES: BEGIN OF ty_mara, matnr TYPE matnr, ersda TYPE ersda, ernam TYPE ernam, laeda TYPE laeda, aenam TYPE aenam, END OF ty_mara. DATA: lt_mara TYPE STANDARD TABLE OF ty_mara. SELECT matnr ersda ernam laeda aenam FROM mara INTO TABLE lt_mara UP TO 10 ROWS.
SELECT matnr ersda ernam laeda aenam FROM mara INTO TABLE @DATA(lt_mara) UP TO 10 ROWS.
[su_box title=”2. Constructor Expressions” style=”soft” box_color=”#f0ab00″]A new type of expression called constructor Expressions are introduced to construct results of specified types and their contents. Below are the list of constructor expressions[su_list]
- NEW creates object
- VALUE creates values
- REF get references
- EXACT perform a lossless assignment or calculation
- CONV convert values
- CAST performs an up cast or down cast
- COND and SWITCH enable conditional expression
[su_highlight]Syntax: VALUE Operator [/su_highlight]
TYPES: BEGIN OF ty_old, f1 TYPE c, f2 TYPE c, f3 TYPE c, END OF ty_old. DATA: ls_old TYPE ty_old. ls_old-f1 = 'A'. ls_old-f2 = 'B'. ls_old-f3 = 'C'. WRITE: ls_old-f1,ls_old-f2,ls_old-f3.
TYPES: BEGIN OF ty_new, f1 TYPE c, f2 TYPE c, f3 TYPE c, END OF ty_new. * creating intial values using constructor expression - VALUE DATA(ls_new) = VALUE ty_new( f1 = 'A' f2 = 'B' f3 = 'C'). WRITE: ls_new-f1,ls_new-f2,ls_new-f3. * changing the initial values using '#' ls_new = VALUE #( f1 = 'X' f2 = 'Y' f3 = 'Z'). WRITE: ls_new-f1,ls_new-f2,ls_new-f3.
