Count sheets/Abc classes

We have a series of smart numbers for example they begin with 004 or other sequences. What I am trying to do is create these in a goup for that section of the store room that they can use from year to year without re-entering lets say 50 items in that group.

I have tried abc classes and groups and have that all defined.

I then go to schedule a count sheet for that group and get no results on the report. I have created a new count with only that abc class. I have read the count sheet oracle documentation and still have not been able to create a count sheet without having to enter the items over and over again.
