Hi Norm
There are many ways of doing that and I am sure that you have already reviewed some of these . To me, categorization of work is like a matrix which has multiple variables which can be used altogether for categorization. And categorization can go to the operation level too. But as I understand your requirement is at the order level:
- Maintenance Activity Type
-Processing group
-System Condition
-Business Area
-Enhancements/Custom Fields
-You can also create Ordr Groups - Transaction KOH1.
I hope this helps.
