Quote To Order Conversion Filtering based on Custom Fields

 Hi,

I have a requirement where only selected products at my quote line items are moved to Order line Item.

For this purpose i have given made use of Advance options of Signals. Under Quotes --> Orders View --> we have a Sales Order Button.

Sales Order button calls signal AutoOrderSalesQuote which calls datamap QuoteToSalesOrder. This signal uses Fins DTU BS and Advanced Option in the data map works. Here in advance Option i have given search spec and its worked fine as per my requirement.

Now my Question is will it work if i make use of Custom Fields for this search Spec. i have tested on my Local by giving Source Filter Specification with value [Auto Order Flag] = "Y" where Auto Order Flag is my custom field. but it did not work. if any one have come across such situation please help me on this.
