Attachments API - FND_DOCUMENTS_PKG, FND_ATTACHED_DOCUMENTS_PKG

Working on attachments need some knowledge of how an attachment functions (Definitions, Entity, Document Category, Entities and Blocks, Primary Keys in attachments (If exists)) in Oracle Apps. To understand the below API and what it actually does its advisable to read the Attachments Chapter in Developers Guide.

Primary Key information that uniquely identifies the product (such as the product_ID).

Below API takes single file from a shared drive and inserts into fnd_lobs. Then it's attached to a particular Id (like order_id, invoice_id..) using the combination of pk1_value, entity name and category. In this example i used PDF as attachment. Quering the table fnd_document_datatypes will give different attachment types.

This sample shows how an attachment API works. You can use it to customize/enhance to requirement.
