Using 'Greater than/less than' in dynamic where condition

Question

Hi Guys,
I am trying to use a logical expression with GT/LT condition in dynamic where, butits giving dump  "expression worngly parenthesised' . My query runs perfectly fine when the logical expression does not have 'GT/LT' . Is there a different way of using GT/LT in dynamic where or is it not posiible at all?? Please find my query below -
IF vendor IS NOT INITIAL.
      i_where_clause = 'a~lifnr = vendor'.
      APPEND i_where_clause.
      CLEAR i_where_clause.
    ENDIF.
    IF to_date IS NOT INITIAL.
      i_where_clause = 'a~zzearliestdep LT to_date'.
      APPEND i_where_clause.
      CLEAR i_where_clause.
    ENDIF.
    IF from_date IS NOT INITIAL.
      i_where_clause = 'a~zzlatestdep GT from_date'.
      APPEND i_where_clause.
      CLEAR i_where_clause.
    ENDIF.
  SELECT aebeln alifnr azzearliestdep azzlatestdep
            bebelp belikz b~kzabs
       INTO CORRESPONDING FIELDS OF TABLE i_podetails
       UP TO max_hits ROWS
       FROM ( ekko AS a INNER JOIN ekpo AS b
               ON aebeln = bebeln )
       WHERE a~ebeln = ebeln AND
            (i_where_clause).

Hi,
Try this -
IF vendor IS NOT INITIAL.
  i_where_clause = 'a~lifnr = vendor'.
  APPEND i_where_clause.
ENDIF.
IF to_date IS NOT INITIAL.
  if i_where_cause[] is not initial.
    i_where_clause = 'AND'
    append i_where_cause.
  endif.
  i_where_clause = 'a~zzearliestdep LT to_date'.
  APPEND i_where_clause.
ENDIF.
IF from_date IS NOT INITIAL.
  if i_where_cause[] is not initial.
    i_where_clause = 'AND'
    append i_where_cause.
  endif.
  i_where_clause = 'a~zzlatestdep GT from_date'.
  APPEND i_where_clause.
  CLEAR i_where_clause.
ENDIF.
Cheers.
