Hi Andrew, The ad_group_criterion.cpc_bid_micros value will change the Max CPC of the specific keyword (or other criterion). If you want to change the max CPC of the entire ad group, you have to do this through the AdGroupService since that service handles changes to the ad group itself.
I'm not exactly sure what you mean by "ad group level is an attribute of ad group criterion". The AdGroupCriterionService only makes changes for the ad group criteria and not for the ad group as a whole. If this still doesn't answer your question, please share a screenshot of the UI showing metric you are trying to change via Reply privately to author so I can further investigate the issue.
