Problem using keyword RANGES

Question

Hi All!
I am coding as below to do some validations :
RANGES : r_uname FOR syst-uname.
r_uname-low  = 'xxxxxx'.
r_uname-sign = 'I'.
r_uname-option = 'EQ'.
APPEND r_uname.
CLEAR  r_uname.
r_uname-low  = 'yyyyy'.
r_uname-sign = 'I'.
r_uname-option = 'EQ'.
APPEND r_uname.
CLEAR  r_uname.
IF sy-uname NOT IN r_uname.
But the if condition is not validating the values in r_uname. What I see is that sy-uname is a structure and r_uname is a Internal Table without a header line because of which the if condition is not validating .Any better coding to get this functionality.

Hi,
Chk A sample code.
Define a range:
Ranges: r_field for <table>.
if not field1 is initial.
r_field-sign = 'I'.
r_field-option = 'EQ'.
r_field-option-low = field1.
append r_field.
endif.
if not field2 is initial.
r_field-sign = 'I'.
r_field-option = 'EQ'.
r_field-option-low = field2.
append r_field.
endif.
if field1 is initial and field2 is initial.
r_field-sign = 'I'.
r_field-option = 'EQ'.
append r_field.
endif.
select * from <table> where field1 in r_field.
