We are dealing with huge payloads and are storing the bulk of data in a separate schema outside of the BPM engine. This data will be surfaced via ADF-BC in a human task UI. I am looking for a method in the BPM API that exposes task access permissions for the logged in user. For example, a particular human task has payload access for Reviewers set to Read. I want to verify the logged in user has permission to update the payload before calling a commit in the BC.
