Multimedia Objects 
Use
You use the SAP Documentation Management System that comes with the SAP system to create or store such elements as formatted text and images (or for electronic media, even video and audio) for your product catalog. Each element is considered a separate document; you assemble these elements within the catalog component and link them to the articles and/or layout areas you have already assigned to the piece.
When you assign an article to a layout area, the basic text and associated documents can be automatically copied from the article master data. In Customizing for product catalog types, you can specify whether text and documents are to be copied automatically or not, and if so, which kinds.
You can display formatted text, images, and so on, by choosing Display Original in the pop-up dialog box where you link the documents to the product catalog. Assuming that the appropriate customizing has been done in the Document Management System, this will start the appropriate application, opening a separate window to display the text or image. While that application is open, you can edit the Product Catalog window.
Prerequisites
You will need to assign each document a document type that allows linkage to layout areas and layout area items. Document type L01, which comes with SAP Retail, allows this linkage.
Although a document may be of type L01, it can have an associated file with one of a number of different formats, such as .doc, .txt, .jpg, .wmf, .avi, .wav.
Integration with the Online Store
Normally an article can have up to three multimedia objects assigned to it: a large image, a small image, and a sound file. You can change the Customizing settings to display additional multimedia objects (for example, .avi or .wav files). You assign these objects in product catalog maintenance and they will appear as hyperlinks in the online store at the product detail level. Depending on whether the customer's browser or viewer application supports a particular file format, clicking on a hyperlink will cause the object to be displayed or be downloaded to his or her PC. Images in .jpg or .gif format will appear as thumbnails next to the hyperlinks.
Multimedia objects are not normally shown in lists, but you can change the Customizing settings and alter the HTMLBusiness template so that they do appear in lists as well as for individual shops and products.
