Checking conditions in SELECT statement

Question

Hi All,
I am relative new to ABAP and I would like to ask a question about checking conditions in SELECT statement in the "WHERE" part.
There are two checkboxes at the selection screen and each should disable one of  conditions (marked with two stars) in the SELECT mentioned below.
My question is, whether there exists an option how to solve this problem without using solution like:
IF checkobx1.
SELECT (without one condition)
ELSEIF checkbox2.
SELECT(without other condition).
ELSE.
SELECT (with both conditions)
  SELECT  qprueflos qherkunft qaufnr qsa_aufnr qmatnr qwerkvorg
          qpastrterm  qpaendterm
          qverid qobjnr vobjnr AS objnr_fa vauart
    FROM qals AS q INNER JOIN vkaufk AS v
    ON qaufnr = vaufnr
    INTO CORRESPONDING FIELDS OF TABLE gt_qals
    WHERE q~prueflos IN s_pruefl
      AND q~stat35     EQ space
      AND q~werk       EQ loswk
      AND q~herkunft IN s_herk
      AND q~offennlzmk EQ 0
      AND q~offen_lzmk EQ 0
      AND q~pastrterm IN s_startt
      AND q~paendterm LE s_endt
      AND v~auart IN s_auart.    "('ZCPA', 'ZCPK', 'ZCBA').

Hi,
With this, I think u can directly read into WHERE clause
IF checkbox1.
    v_where = '& BETWEEN ''&'' AND ''&'' '.
    REPLACE '&' WITH key_field INTO v_where.
    REPLACE '&' WITH field_LOW INTO v_where.
    REPLACE '&' WITH field_HIGH INTO v_where.
    CONDENSE v_where.
ELSEIF  checkbox2.
    v_where = '& BETWEEN ''&'' AND ''&'' '.
    REPLACE '&' WITH key_field INTO v_where.
    REPLACE '&' WITH field_LOW INTO v_where.
    REPLACE '&' WITH field_HIGH INTO v_where.
    CONDENSE v_where.
ENDIF.
select * into corresponding fields of table ITAB
             from (table_name)
            where (v_where).
In this key_field is your fieldname in the where clause and field_low, field_high are range of values.
If i write static query it looks like this
RANGES: MATNR1 FOR MARA-MATNR.
  MATNR1-LOW = MATNR_LOW.
  MATNR1-HIGH = MATNR_HIGH.
  MATNR1-SIGN = 'I'.
  MATNR1-OPTION = 'BT'.
  APPEND MATNR1.
select * into corresponding fields of table itab
from mara where matnr BETWEEN 'M100' AND 'M200'.
Hope it helps u
thanks\
Mahesh
