This is called a mid-career switch. I am the best example here.
1- pick which business process you love the most. Sales/Procurement/Manufacturing/HR/Finance
2- Find a free course on the module you chose in open.sap.com
3- I always suggest getting certified - as you will learn the module completely. Learning hub is the best place
4 Read blogs / you tube videos /Linkedin articles on the module you are following
5 Once certified, be in touch with a recruiter for opportunities.
6 Post blogs /Article in Blogs.sap.com /Linkedin to get attention from recruiting agencies .
