In contrast to other languages where we need to make use of its basic value to initialize the variables, in SAP we don't have to make such thing. Besides initialize or clear a variable with its basic value like integers to zero and strings to space(s), in SAP we can make use of the command 'CLEAR' that can also be used with any variable and structure. For example:



The same applies to work areas;

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12

TYPES: BEGIN OF ty_data,
  matnr TYPE matnr,
  value(2) TYPE n,
  erdat TYPE erdat,
END OF ty_data.

DATA wa_data TYPE ty_data.
wa_data-matnr = '1'.
wa_data-value = '01'.
wa_data-erdat = sy-datum.

WRITE: 'Work area with data', wa_data.

CLEAR wa_data. " All members initialized

WRITE: / 'Work area cleared', wa_data.

DATA: lv_number TYPE n, lv_char type c.
lv_number = 1.
WRITE lv_number.
CLEAR lv_number. " Initialize to 0
WRITE lv_number.

lv_char = 'A'.
WRITE lv_char.
CLEAR lv_char. " Initialize to space[s]
WRITE lv_char.
