Duplicate Document Detection

Why:

To prevent data redundancy and double processing (Inflated costs).

What:

Identify and flag duplicate document uploads based on file hash and extracted data.

• Supplier
• Document ID
• Subtotal
• No of Line items
• Gross Total

Add a filter do duplicate docs

Acceptance Criteria:

• Unique file hash generated for each document.
• Duplicate alerts are shown to the user during upload.
• Option to “View Existing Document” when a duplicate is detected.

Edge Cases:

• Same document with minor edits or re-scans.
• Files renamed but identical in content.
• User orders 40 bricks. Vendor delivers the first 20, then delivers the second 20. System shouldn’t mark this as a duplicate as while the DN will be identical, it’s not a duplicate
