In this scenario, since you parameterized the schema name, table name and configured the ports to be picked up dynamically, you can point the source to any table (passed from parameter file). In this case, you will build the mapping with one sample table and you will deploy the mapping with that data object. But you can pass any table at runtime and the mapping will work. You will NOT need to import the other tables into the MRS as data objects or deploy them as part of the applications
