PXSelector with left outer

Hi Team,

I need to filter out vendors who are not in the my custom table (HMRCVendorRegisterDetail). I wrote following but it is not showing me the results. Any alternative for this?

Only one vendor code is exists in the HMRCVendorRegisterDetail table 

[PXSelector(typeof(Search2<BAccount.bAccountID, LeftJoin<HMRCVendorRegisterDetail, On<BAccount.bAccountID, 
            Equal<HMRCVendorRegisterDetail.bAccountID>>>, Where<BAccount.type, Equal<BAccountType.vendorType>,And <HMRCVendorRegisterDetail.bAccountID, Equal<Null>>>
            >),
                    typeof(BAccount.acctCD),
                    typeof(BAccount.acctName),
        SubstituteKey = typeof(BAccount.acctCD),
        DescriptionField = typeof(BAccount.acctName))]
