for example, if you disable primary key constraint, it is possible to enter the duplicate value in primary key column and commit the same data in table. Problem will arise if you try to enable the primary key. If your table is small it easy to judge what rows have invalid values but this problem will become a junk when your table is big, say millions of row. but not to worry oracle database has a process to identify those row which have some invalid data as per the constraints.Therefore, data that passes the validation process is loaded into OWE and MDW target tables, while data that fails the validation process is redirected to separate error tables in the OWS.This ensures that flawed data never finds its way into the target OWE and MDW tables.In this step, you select the Access tables that you want to upsize to the SQL Server database.Select the tables that you want to upsize, and then use the arrow buttons to move them to the Export to SQL Server list.
