Hello,

eligibility for MBA lateral entry is :- a candidate should have a PG diploma degree in business management.

if you have done MBA then you can't do it again. if you want to know or have knowledge n skills then you have to read it as external course. for learning, you can get many private webpages who provide it.

if you want job option in supply chain management then you can take course from universities like edx, course-era. they provide certificates approved by international universities when you qualify the exam.

You can show-case the certificate to your interviewer as and when they ask for which will represent that you studied and have some knowledge regarding the domain.

Hope it helps!
