Thanks. I know the document link to EBS application, but I could not find any CRM documents on this link.Please select your application release from the link referenced above and search for CRM -- You should find CRM manuals there ("Oracle Applications CRM System Administrator's Guide").
I am not sure whether there are some links documents on CRM which built on EBS R12 edition.
And Oracle has released the CRM on Demand Release 19. I also not sure it refer to R12 or it is a standalone product.Oracle CRM On Demand Documentation
