Service categories are used to group publications together. For example in category 1, a main publication may have several smaller related publications underneath it, entering the main publication code in the category 1 of the other publications would link them together. Or, for example you could group together publications that are distributed overseas in category 2.
You can assign categories to Publications to group them together when they are being set up, see Publication Set Up.
