3753710 - Attachment Preview Disabled in SAP Business ByDesign Release 2602

After upgrading to SAP Business ByDesign release 2602, users are no longer able to preview attachments directly in the browser or in a new browser tab.

Instead of opening inline, attachments are automatically downloaded to the local machine.

This behavior is observed in scenarios such as:

• Opening attachments from business documents
• Viewing documents through Output History
• Accessing files through File Management

SAP Business ByDesign

1. Select any business document containing attachments or generated output documents.
   Example:
   Customer Invoice
   Sales Order
   Supplier Invoice
2. Open the Attachments tab or Output History section.
3. Select a PDF, Excel, Word, or other supported document.
4. Select attachment name or preview. 
5. Observe the document is Automatically downloaded.  

As part of SAP security best practices, SAP has disabled browser-based preview functionality for attachments and generated documents.

Previously, attachments could be opened directly inside the browser window or a new browser tab. Starting with release 2602, files must first be downloaded locally before they can be viewed.

This change is designed to reduce exposure to browser-based vulnerabilities and improve overall document handling security.

This behavior is expected and represents a product enhancement introduced with SAP Business ByDesign release 2602.

Users should:

1. Download the attachment to their local device.
2. Open the file using the corresponding native desktop application.

Example:

• PDF files → Adobe Acrobat Reader
• Excel files → Microsoft Excel
• Word documents → Microsoft Word
