It means to know very well, thoroughly in any business, to know how to act in any circumstances: who to contact, what to do, etc.д. In some cases, this is what they say about the arrangement of affairs by acquaintance, i.e.е. When a person has useful connections in the business, which makes it easy to bypass all the obstacles and get what you want.
