Leadership less focused on career develoments: Sometimes is unclear the path for growth in each role and it feels that it may take longer than expected to grow , which is why a lot of competitors steal great talent form SAP. Although there are great leaders all around the company, a lot of them are way more focused on achieving the results than on the growth of their team, so there's room for improvement here.
Other than that, SAP is by far the best company I've worked for and HIGHLY recommend it.
