Teradata @ your service ID would help you open incidents on defects/concerns/documentation/general information related to teradata.
This service is available to the companies which are running teradata.When a Incident is opened, teradata would ask for site ID to validate your request.
I suggest you to have your manager apply for a TD@YS ID for you.Once you get the ID you will have access to all the documentation,software patches,orange books related to Teradata.Through TD@YS Id you will be able to contact Teradata customer service when there is any problem with your teradata software/installation.
Teradata identifies your companies teradata installation through site IDs. for example if your company name is Bingo and you have two installations of teradata, say development and production.Teradata would identify each installation using a site ID say for eg:- BNG01 for dev and BNG02 for production.
So when you raise a incident with teradata for production issue you should provide site ID as BNG02.
