No result if one field is blank

Question

Hi all,
in my module pool screen i have 4 input fields (no selection or ranges, its like parameters). To get the value based on that i am using this query.
  SELECT *
          FROM LTAK
          INTO TABLE GT_LTAK
          WHERE LGNUM = GV_LGNUM
          AND   KQUIT NE 'X'
          AND   BNAME = LV_BNAME
          AND   BWLVS = LV_BWLVS
          AND   BENUM = LV_BENUM.
If i fill all these 4 values i am getting the output. If i leave a field blank i dont get the result.
Can anyone please help me.
Regards,
Nik

Hi,
Create the ranges and pass to the where condintion to the select instead of the parameters.
If you pass the blank in the parameters then the select will check with blank values in the table instead if you use the ranges then blank values will not be considered in the selection.
RANGES : R_BNAME FOR LTAK-BNAME,
                 R_BWLVS FOR LTAK-BWLVS,
                 R_BENUM FOR LTAK-BENUM.
IF NOT LV_BENUM IS INTIAL.
R_BENUM-SIGN = u2018Iu2019.
R_BENUM-OPTION = u2018EQu2019.
R_BENUM-LOW = LV_BENUM.
APPEND R_BENUM. CLEAR R_BENUM.
ENDIF.
