Best Practice to investigate HCP Document Repository issues

Hi,

Our HCP product is using HCP's Document Repository to store business documents from Fiori apps. Occasionally we encounter issues from Doc. Repo., such as files are missing or only part of files are listed, etc.

I would really appreciate it if HCP Doc. Repo. experts can provide us some tips/tricks and best practices on how to investigate those issues, say where to find logs and how to interpret common issues from the logs, etc.

Thanks and best regards,

Ken Huang
