As advised by my friend CA. Bharat Hirde (when he was yet to qualify the CA Final), SAP consulting is not a good career choice for the qualified CAs, because you have to compete with non-CAs and nos. of implementation experience and SAP certifications bears more weightage than a professional degree and business processes / controls experience.
But in the auditing and management field in corporates, professionals with business processes efficiency and controls expertise always dominates.
Plese do also my old posts on this topic.
