I can't find InterCompanyAutoCreateOrders of CustTable on the Table Browser in DAX2009

We have a Dynamics AX2009 server　include GLS layer but we can't find InterCompanyAutoCreateOrders of CustTable on the Table Browser even if this is set by Yes on the Visible’s property.　More and more If　we get a value of this using DictField class, It was the value of No.

Could anyone tell me why it occurred?

Thanks
