Before you import metadata, you can configure the import file to generate value tests. For example, to generate value tests for the CustDetail_CustStage table pair, add the following lines at the end of the table pair definition in the import XML file:
When you import metadata from an XML file, you can overwrite repository objects that have the same type and same name as the objects you import. If you do not overwrite objects and an object with the same name and same type exists in the repository, Data Validation Option does not import the metadata.
When you import the metadata, you can also edit the metadata. You might change the metadata based on the environment in to which you import the metadata. For example, you can change the connections, flat file locations, Data Validation Option repository, and PowerCenter repository that stores Data Validation Option objects.
