*- type declarations
 DATA(lv_text) = 'Declaring variables'.
 DATA(lv_count) = 1000.
 
*- using value to create internal tables
 DATA lt_matnr TYPE STANDARD TABLE OF matnr.
 lt_matnr = VALUE #( ( 'a' ) ( 'b' ) ( 'c' ) ( 'd' ) ( 'e' ) ).
 
*- another way of declaring same with type
 TYPES:t_matnr TYPE STANDARD TABLE OF matnr WITH DEFAULT KEY .
 DATA(lt_data) = VALUE t_matnr( ( 'a' ) ( 'b' ) ( 'c' ) ( 'd' ) ( 'e' ) ).
 
*- filling data into an internal table with structure
 DATA:lt_bukrs TYPE RANGE OF bukrs.
 lt_bukrs = VALUE #( sign = 'I'  option = 'EQ'
 ( low = '0001' )
 ( low = '1000' )
 ( low = '2000' )  ).
 
*- declaring work area variable for loop
 LOOP AT lt_matnr INTO DATA(ls_matnr).
 ENDLOOP.
*- declaring field symbol variable for loop
 LOOP AT lt_bukrs ASSIGNING FIELD-SYMBOL(<ls_bukrs>).
 ENDLOOP.
 
*- declaring field symbol variable for read table
 READ TABLE lt_matnr ASSIGNING FIELD-SYMBOL(<ls_matnr>) INDEX 3.
 IF sy-subrc EQ 0.
 ENDIF.
*- getting same data with using table expression
 DATA(wa_matnr) = lt_matnr[ 3 ].
 
*- another examples of table expressions
 DATA(wa_bukrs) = lt_bukrs[ low = '1000' ].
 
*- check if line exists
 IF line_exists( lt_bukrs[ low = '1000'] ).
 ENDIF.
 
*- iteration with 'FOR'
 DATA(lt_material) = VALUE t_matnr( FOR ls_material IN lt_matnr ( ls_material ) ).
 
*- another use of 'FOR'
 TYPES : BEGIN OF t_year ,
   year TYPE numc4,
   END OF t_year,
   tt_year TYPE STANDARD TABLE OF t_year WITH EMPTY KEY.
 DATA(lt_years)  = VALUE tt_year( FOR i = 2000 THEN i + 1 UNTIL i > 2020 ( year = i ) ).
 
 LOOP AT lt_years ASSIGNING FIELD-SYMBOL(<ls_year>).
   WRITE / <ls_year>-year.
 ENDLOOP.
 
*- using 'COND' for declaring new variables
 
 DATA(lv_status) = 'S'.
 DATA(lv_status_text) =
   COND string(
     WHEN lv_status = 'A' THEN 'Aborted'
     WHEN lv_status = 'S' THEN 'Success'
     WHEN lv_status = 'F' THEN 'Failed'
     ELSE 'Status not found' ).
 
 WRITE / lv_status_text.
 
*- we can use 'SWITCH' for declaring conditional operators
 DATA(lv_status_text2) = SWITCH string( lv_status
     WHEN 'A' THEN 'Aborted'
     WHEN 'S' THEN 'Success'
     WHEN 'F' THEN 'Failed'
     ELSE 'Status not found' ).
 
 WRITE / lv_status_text2.
 
*- CONCATENATE is easy
 DATA(lv_time_string) = |Date: { sy-datum } / { sy-uzeit } Status: { lv_status_text } |.
 WRITE / lv_time_string.
 
*- you can use embedded expressions for many string operations
 DATA:lv_ebeln TYPE ebeln VALUE '490001'.
 DATA(lv_purc_no) = |{ lv_ebeln ALPHA = IN } |.
 WRITE  / lv_purc_no.
 
 DATA:lv_decimal TYPE p DECIMALS 10 VALUE '123.456789'.
 DATA(lv_money) = |{ lv_decimal DECIMALS = 2 } |.
 WRITE:lv_money.*- using case statement in database access
 SELECT werks,
        CASE WHEN land1 = 'DE' THEN 'IN'
             ELSE 'OUT'
        END AS country
   FROM t001w INTO TABLE @DATA(lt_werks).
 
 LOOP AT lt_werks  ASSIGNING FIELD-SYMBOL(<ls_werks>).
   WRITE: / <ls_werks>-country,<ls_werks>-werks.
 ENDLOOP.*- fill ranges/tables directly from select with default valuesDATA:lr_range TYPE RANGE OF matnr.
