New Attachment functionality

I am in the process of identifying where the new attachment functionality for each module.  Is there any documents that are available that have the navigation, page, record that now has the attachment functionality in 9.1

I search metalink and found a document for Expense.  It would be great if I could get this information for the AP and Treasury modules.  For example of what I am looking to idenify is:

·        Create Expense Report – Expense Report Entry

o   Object:  EX_SHEET_ENTRY

o   Employee Self-Service, Travel and Expense Center, Expense Report

o   Location:  Header
