re: Ora Apps ERD's

hi all,
  anyone working w/ the slew of Oracle Apps out there?   I'm looking to print out master ERD's, for each of the schema's --for learning purposes -- including the columns, joins, pk's, fk's and find that the eTRM's on metalink are woefully incomplete.    

  Any way around that, are there better/more complete resources.... other than reverse-engineering schema's with ERWin or some other tools.... which will involve extensive manual object alignment and the like?    

  thx much,
  Cos
