I m a mechanical engineer with close to 11 years of experience in product development, project management. I have completed post graduation in business administration. I m presently a Project manager in a product based company. My specialization is Computer aided design (CAD) I am planning to switch to SAP for better career opportunities. What module should i focus on? Is SAP-PLM a good option or should i look at PP, MM or something else? Kindly advise how should i go about learning the modules?
