"So my question is that do i need to have my degree from outside Germany recognized, and if not, then what should i do next with my APS, and is there place to submit my APS certificate during the application process."
1) You have to distinguish between two different purposes for which recognition of foreign educational qualifications may be relevant.
a) Recognition of a first university degree (usually a bachelor's program) which qualifies for a master's program.
This is currently only done for two specific master's program at Universität Hamburg, including "M.A. International Business and Sustainability".
Please read this document containing country-specific information, our FAQs and a step-by-step guide for using the Universität Hamburg recognition portal
b) Recognition of school and/or university degrees to apply for an undergraduate degree program. This admission requirement (a so-called "higher education entrance eligibility") applies to all bachelor's and state examination programs.
Most information on the website Recognition of foreign educational qualifications
relate to the recognition in regard to this general access to a German university, not tho the recognition of a bachelor's degree which qualifies for a specific masters program.
Therefore, the information in your screenshot is not relevant for an application for "M.A. International Business and Sustainability".
