Info Records Conditions Change History Tables

When a change is made to a info record condition the changes are logged in CDHDR & CDPOS. CDPOS includes the old and new value of the change but it doesn't tell me which specific condition was changed. For example I changed condition PB00 and went to CDPOS and could not determine from CDPOS which condition was changed. I am missing a table that would tell me the condition that was changed.

Any help would be greatly appreciated.
