In principle, both a combination of a DPA and SCCs as an annex (with the SCCs taking precedence in the event of conflicting clauses) and the sole use of only the SCCs are possible. In this respect, it is an individual company decision. The advantage of the SCCs is that they can be concluded quickly and without problems due to their unchangeability. An additional DPA, however, offers the advantage that it can contain more extensive regulations or individualizations, which it does in many cases.
