SAP

This would depend which track you would want to take up and generally consultants get that clarity after 3 - 4 years of being consultants. For an I.T. company there are typically 2 tracks:
Consultant: Wherein you spend more time on the system and eventually graduate to being a Principal Consultant / Technology lead by gaining more experience and in varied projects. Formulate high solutions for new implementation or work on complex requirements or integrations. It might also involve management of competency & resources within the organization.
Project/Delivery Management: Wherein you spend more time managing resources & client servicing and providing more depth to client portfolios by suggesting implementation of updated tools or new functionalities. Clients also expect you to be a partner and not just a vendor who only does what he is told to. It also involves pitching for new clients & getting new projects for the organization.
Most often it has been found that these 2 roles are merged in many companies.
Additionally, being a part of an internal IT team for product based company, there are opportunities that involve progressing towards CXO functions where you can manage a number of technologies (depending on the scope of the organization).
