Loading flat files to Teradata

[Cbick]

I am new to Teradata. I am trying to load a flat file created in SAS into Teradata. I have already created my populations and have been told that I need to load the flat file into Teradata and then recreate my segment populations over again. Can a flat file be loaded into Teradata without recreating work that has already been done?

Thanks.

Your question is very vague, but if the poulation identifier is an element of the input file, I don't know why you would have to do the work over.
