Plant Maintenance Implementation

Hi I have been asked to do my first implementation of the PM module specifically for maintenance lists for serial/ batch controlled items by a client. Can someone please assist in this with relevant documentation that will help.

Also I have a part b to this. The client has been specific in saying that unique identification of units could be achieved by either equipment masters which is what I would have chosen but he has also gave an option to achieve similar and quoted "this may be acheived by chapter 5 issue using batch or serial number". Has anyone ever heard of this terminology "Chapter 5 Issue", is it SAP?
