Webtrends Analytics 9 Adminstration Guide, November 2012
When modifying the campaigns.csv or products.csv translation files to use your own data, Webtrends recommends modifying these translation files rather than creating new ones.
If you are creating more than one version of products.csv or campaigns.csv, copy the original file and preserve the original column structure as described in Step 3.
It is technically possible to create campaigns and products drilldown reports based on a translation file that uses different number of dimension columns or a different order of dimensions than those used in the default CSV files. However, with this method, translation occurs once for each corresponding dimension in each report, rather than only once during Visitor History processing. The number of lookups required to create the drilldowns is thus much larger, and increases dramatically with any increase in the number of drilldown reports or in the size of the translation file. Because of the potential performance and scalability problems associated with these extra lookups, it is best to use only the methods described in this document to modify the campaigns and products translation files.
