Understanding a Report

Ok guys and gals,
As I stated not long ago. I am a NEWBIE to GM Parts Management. Every Month my boss has me print off a report - Inventory Value List - Dealer.
This month I did it and he comes back with questions I can not answer. So here I am. The report says my % SP value of Inventory is 44. So to me that means 44 % of my inventory is covered by RIm. And my % non SP value of inventory is 56. So to me that means 56 percent of my inventory is not covered by RIM. Am I correct? If I run this report over a years span the numbers are pretty consistent across the board. My boss wants to see the percentages reversed. How Do I go about doing that. I have been trying to get a handle on the RIM situation But I am still learning. When special parts are ordered, They are billed ASAP. Most of the time Billed when ordered. I keep outside purchases to a min from places like NAPA, Oreilly ect.
What Am I doing wrong? any help would be greatly appreciated.
