I am working in the QM module for more than a year & now I am thinking of going for QM certification ........Can any one pls tell me what is the overall certification fees of the exam ...... & from where I can get the detail syllabus for that ..........
Check these links for certification info on two modules mentioned by you.
SAP Product Lifecycle Management- Quality Inspections (QM-IDI) [original link is broken]
You can search in http://www.sapfans.com/ under BookStore. I would rather suggest you to go through the documentation on help.sap.com. It is the best.
But, are you looking for certification material or general material on QM.
