Internal Table [DEFAULT] Expression

Internal Table [DEFAULT] Expression

SCARR table entries

While reading ITAB with key or index the DEFAULT expression can be added. In case the read is unsuccessful then the default value is assigned to the target value holder.

below here the s2nd read is unsuccessful, so the target  LS_SCARR2 is assigned to the default structure value.

SELECT * FROM scarr INTO TABLE @DATA(lt_scarr).
DATA(ls_scarr_def) = VALUE scarr( mandt = sy–mandt carrid = ‘XX’ carrname = ‘NOT ASSIGNED’  currcode = ‘XXX’ url = ‘NO URL’ ).

DATA(ls_scarr1) = VALUE #( lt_scarr[ carrid = ‘AA’ ] DEFAULT ls_scarr_def ).
DATA(ls_scarr2) = VALUE #( lt_scarr[ carrid = ‘ZZ’ ] DEFAULT ls_scarr_def ).
