Passing date parameter

Hi..

I'm a newbe using Oracle e bussiness suite 12 and developing report use Oracle Report Builder 10.1.2.0.2.

I have a problem with passing date parameter from oracle report builder to oracle application.

I set the user parameter :

name  = date_start

data type = date

width = 11

input mask = DD MON RRRR

on sql query :

TRUNC(OE_ORDER_LINES_ALL.SCHEDULE_SHIP_DATE) >= TO_DATE((:date_start),'DD-MM-YYYY HH24:MI:SS')

on application, i set the value to : FND_STANDARD_DATE

when i run it on my EBS application, i entry : 01-JAN-2013

but the result was "Completed error"

and the error log was :

Current NLS_LANG and NLS_NUMERIC_CHARACTERS Environment Variables are :
