Check if field has value 0 - zero value on field

Question

Hi,
I've got the following code:
DATA: v_qtd TYPE i.
SELECT-OPTION s_qtd FOR v_qtd.
I'm using a Z table Z001 and there's a numeric field there that's filled with values >0 (greater then zero).
If I have 6 materials and only 4 have the field QTD with a value:
MAT 1000 QTD 1
MAT 1002 QTD 5
MAT 1003 QTD 1
MAT 1005 QTD 2
MAT 1001 and 1004 exist but don't have any entries in table Z001.
I'm making a report to get the values from table Z001 depending on how s_qtd is filled.
My problem is how can I get the materials 1001 and 1004? How can I check if s_qtd is the value 0 (zero)?
If I check s_qtd IS INITIAL then I get all the materials (1000 to 10005).
If I check s_qtd-low = 0 it's the same as IS INITIAL.
IF s_qtd IS INITIAL.
     (all materials 1000 - 10005)
ELSE.
     IF s_qtd IS NOT INITIAL.
          (materials with entries in Z001 1000, 1002, 1003, 1005)
     ELSE.
          (never gets here)
I can't check s_qtd-low = 0 and s_qtd-high = 0 because it's the same as s_qtd IS INITIAL.
Thank you.

Hi Carlos,
Try the below code:
TABLES: z001.
DATA: it_z001 TYPE TABLE OF z001,
wa_z001 TYPE          z001.
SELECT-OPTIONS: s_num for z001-qtd.
START-OF-SELECTION.
IF s_num-low is INITIAL and s_num-high is INITIAL.
SELECT *
from z001
INTO TABLE it_z001.
ELSEIF s_num-low is not INITIAL and s_num-high is INITIAL.
SELECT *
from z001
INTO TABLE it_z001
WHERE qtd eq s_num-low.
ELSEIF s_num-low is NOT INITIAL and s_num-high is not INITIAL.
SELECT *
from z001
INTO TABLE it_z001
WHERE qtd BETWEEN s_num-low and s_num-high.
ELSEIF s_num-low is INITIAL and s_num-high is NOT INITIAL.
SELECT *
from z001
INTO TABLE it_z001
WHERE qtd BETWEEN s_num-low and s_num-high.
ENDIF.
LOOP AT it_z001 INTO wa_z001.
WRITE:/ wa_z001-mat, wa_z001-qtd.
CLEAR: wa_z001.
ENDLOOP.
