The approval(s) from truumaa do(es)n't fullfill the approvers requirements because:

• The approver's cost centre, ENGSPN, maps to the ENGINEERING business function. As the code that was changed is owned by PLATFORM, this approval won't satisfy our separation of duties check. We'll need an additional approval from someone in PLATFORM. This approval may still help satisfy other codeowner requirements.
