Channel 2: Join a company that is or will soon implement SAP. After the project is completed and supported for a certain period of time, I have the ability to join a consulting company as a full-time implementation consultant.
Channel 3: self-study, with the help of forums and Q groups, self-study with IDES as the platform, and then apply when the time is ripe.
Channel 4, good luck, just happened to meet the consulting company to recruit novice consultants.
