Internet Expense Attachments using fnd_webattach.add_attachment

Hello All,

Our requirement is to add attachment to Expense Report header and Line level from PLSQL code. As we know that we can add attachments using fnd_webattach.add_attachment method from PLSQL.

But this method needs to pass function name and entity name as input along with primary key. I have two questions regarding calling this method to add Internet Expense attachments,

1) What FUNCTION_NAME should I pass to this so that I can view this attachment from Internet Expense responsibility too?

2) I found that OIE_LINE_ATTACHMENTS is the entity name for the line level attachments but when I tried to query it in FND_DOCUMENT_ENTITES table this entity name does not exist. Can some one explain why it does not exist in this table if it is used as attachment entity?
