With the Document Viewer, you can display documents either in a browser within the SAPGUI window or in a separate browser window.

Introductory notes

You can use the Document Viewer whenever you want to enable the user to display documents but not to change them. In contrast to conventional office integration technologies, the Document Viewer is supported by the SAP GUI for HTML.

integration

You are using the SAP GUI from version 4.6c. The Document Viewer is compatible with both the SAP GUI for Windows and the SAP GUI for HTML.

The following components must also be installed on your PC:

• Microsoft Internet Explorer version 4 or higher

• The desktop application required for the type of document you want to view (eg Word for DOC files)

You can use the SAP Business Document Service to store documents. The URL addresses or internal tables returned by the BDS can be used directly in the methods of the document viewer interface.

Features

With the Document Viewer you can display documents either in a browser within the SAP GUI (for Windows or HTML) or in a separate browser window.

In contrast to conventional office integration technologies, the Document Viewer is compatible with the SAP GUI for HTML.

The ABAP programming interface for the Document Viewer is available via the global interface i_oi_document_viewer.

The Document Viewer supports HTML as well as the following document types:

Document type	extension	ProgID in the registry
Microsoft Word document	.DOC	Word.Document
Microsoft Excel workbook	.XLS	Excel sheet
Microsoft PowerPoint presentation		PowerPoint show
Rich text format	.RTF	Application, the files of this type in the Windows dialog box Open with assigned
Portable document format	.PDF	Application, the files of this type in the Windows dialog box Open with assigned
Quicktime movie	.MOV	Quicktime.Mov
Lotus 123 workbook	123	Lotus123.Workbook
Lotus Word Pro document	LWP	Wordpro.Document
Visio graphics	VSD	Visio.Drawing

These document types are definitely supported. Depending on the range of functions of the web browser used, it may be possible to display further types.

The Document Viewer is based on the plug-in mechanisms of the web browser used. This determines the format of the document and the application required to start the document in order to display the document. To do this, the browser uses the following information from the Windows registry:

HKEY_CLASSES_ROOT \. ***	Content type and ProgID
HKEY_CLASSES_ROOT \ <ProgID> \ shell \ open \ command	Application path
HKEY_CLASSES_ROOT \ MIME \ database \ content type	extension

These entries can be created in the following two ways:

• When installing an application. When you install Word, for example, the file type .DOC is registered on it.

• The first time you open a file with an unregistered extension. In this case, the Open With dialog box appears , in which you must assign an application to the extension.

restrictions

It is currently not possible to edit or save documents in the Document Viewer.
