Here is link to SAP Help Portal http://help.sap.com/ That can help you need.
You could purchase a book called SAP r/3 Plant Maintenance by Britta Stengl & Reinhard Ematinger. It is aimed at intermediate users but is very good. If you are completely new to PM, it may be aimed a bit high but there would still be value in reading it.
We are planning to implement SAP-PM. I have only come across old SAP R/3 manual; however, I suggest you please go through the SAP demo/tutor by visiting the website: http://help.sap.com/bp_utilitiesv1500/UTL_India/html/ In the above website, please select, Business Information. Then select, Preconfigured Scenarios. Then select scenarios like U70. Then download the required software before playing the tutor. There is a word document that supports understanding the tutor. Scenarios U70: Complete Order Process U71: Equipment Construction Management U72: Preventive Maintenance U73: Overhaul Management U74: Refurbishment Management U75: Work Clearance Management U76: Reliability Centered Maintenance U77: Raw Material (Coal) Procurement Regards.
