Thank you for your help.
If i want to consider penalty for the model that predict the wrong outcome, what is actual outcome? it is the output for instance in trainig dataset(target)?
In other word, the penalty considers while the models create(in training model) then in testing we accept the outcome of model that have best prediction?

yes,in above code dt was filled and have all the row that i want but there is database logon error .also i changed my code to below and there is no error but report is empty but dt is filled.
Dim cls As New Cls_Cust_Bill
Dim dt As New DataSet("DS_CustomerTransaction")
dt = cls.Search_Cust_Bill_RPT(ArrStr(0))
dt.Tables.Add("CustomerBill")
dt.Tables.Add("Transactions")
Dim oRpt As New Crp_Cust_suratHesab()
oRpt.SetDataSource(dt)
oRpt.SetParameterValue("filter", ArrStr(1))
CrystalReportViewer1.ReportSource = oRpt
CrystalReportViewer1.DataBind()

in second question ,I click ok and drag and drop my neccesary fields to the report.
my dataset has two adapter(CustomerBill,Transactions).but i have a error database logon failed.i think there is a poblem with my code behind:
Dim dt As New DataSet("DS_CustomerTransaction")
dt = cls.Search_Cust_Bill_RPT(ArrStr(0))
dt.Tables(0).TableName = "CustomerBill"
Dim oRpt As New Crp_Cust_suratHesab()
oRpt.SetDataSource(dt)
CrystalReportViewer1.ReportSource = oRpt
CrystalReportViewer1.DataBind()
