If you are using a test
environment and staging new data for a new data source for the first
time, you might not want to implement duplicate-data checking macros.
To do so, on the Duplicate Checking page
of the Staging Parameters tab of the staging
transformation, set the Enable duplicate checking field
to No. This setting provides more flexibility
as you process different types of sample files. Once you are satisfied
with the results of your tests, you can purge the IT data mart and
choose whether to implement duplicate-data checking by specifying
parameters in the staging transformation.
Note: If you edit the generated
source code to modify the mode for duplicate-data checking, then your
changes to the code are lost if the job is regenerated or redeployed.
Although you can save the functionality of the source code to the
local file system, the original source code is preserved. In addition,
the mode for duplicate-data checking is not updated in the SAS Metadata
Repository entries.
