DBDataSource with Conditions doesn't filter

Hi,

I have created a custom table using SQL (instead of User Table)

I am able to retrieve the data from the table without a problem. However, Condition Object does not filter,my codes as below

oCondition = oConditions.Add

oCondition.Alias = "ItemCode"

oCondition.Operation = SAPbouiCOM.BoConditionOperation.co_EQUAL

oCondition.CondVal = itemcode

Does the Condition object work on custom table?
