Please go through the collection of some basic inline declarations frequently used in ABAP new syntax coding.
*<!-- Declaring variables without data element --> DATA(lv_text) = 'My Text'. *<!-- Select statement --> *-- Single field SELECT SINGLE bukrs FROM bkpf INTO @DATA(lv_bukrs). *-- Multiple Fields SELECT SINGLE bukrs, belnr FROM bkpf INTO (@DATA(lv_bukrs), @DATA(lv_belnr)). *-- Work Area SELECT SINGLE bukrs, belnr, gjahr FROM bkpf INTO @DATA(ls_bkpf). *-- Internal Table SELECT bukrs, belnr, gjahr, budat, bldat FROM bkpf INTO TABLE @DATA(lt_bkpf) WHERE bukrs = @lv_bukrs AND belnr = @lv_belnr AND gjahr = @lv_gjahr. *<!-- Creating instance of class using NEW keyword instead of CREATE OBJECT --> DATA(lo_object) = NEW zcl_my_class( ). *<!-- Return parameter of a method in OO-ABAP --> DATA(lv_return) = zcl_test_class=>meth1( ). *<!-- Method parameters --> lo_object->my_method( ( IMPORTING iv_param = DATA(lv_value) ). *<!-- Looping at internal tables --> LOOP AT lt_itab INTO DATA(ls_line).
