Please read very carefully the note which I mentioned.
Not all corrections can be performed by running the report in update mode (according to SAP) and if you attempt perform manual corrections before their support expert investigates the situation, it will be more difficult for him/her to investigate and suggest the best approach.
I believe that the people, who stated that the report can correct such inconsistencies, first contacted SAP support and ran it in update mode only when/if the support expert asked them to do that.
Not following the correct procedures is one possible reason to have that kind of problem in the first place, please do not deviate from the note recommendation.
