UDO Registration

I'm trying to register UDO by coding with the Find series checkbox to be chacked.

This is my code

Dim bonUserUDOMD As SAPbobsCOM.UserObjectsMD = gonComCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oUserObjectsMD)

bonUserUDOMD.CanFind = SAPbobsCOM.BoYesNoEnum.tYES

But my UDO is registered with Find series Unchecked.

How to SOlve it?
