Mobile Enterprise Buyer (SAP Library - mySAP Supplier Relationship Management)

Mobile Enterprise Buyer

Use

Users can log on to the Enterprise Buyer system using a WAP-enabled cellular phone or any other WAP-enabled front end. This allows them to perform many procurement tasks completely independently of any docking station. These mobile applications are part of the standard system setup for Enterprise Buyer.

Example

Managers can approve shopping carts while on business trips far away from the office.

The start URL for the mobile scenarios is:

http://<host_name>.<domain_name>:<port>/scripts/wgate/wapbbpstart/!?~language=<language>

where <language> = de or <language> = en, for example.

The initial screen is displayed in the relevant language.

Integration

You can either use your own WAP gateway or you can use a WAP gateway service from a telecommunications provider. If you have your own gateway, you can position it behind your firewall. This means that communication is via a dialup line as far as the WAP gateway, that is, a secure connection going behind the firewall. Beyond this point, communication is via HTTP. If you are using a WAP gateway service, the dialup line stops outside your firewall with the less secure HTTP communication starting outside the firewall.

The graphic shows a standard configuration with a WAP gateway located behind the firewall.

Prerequisites

You require the following:

WAP-enabled mobile device
WAP gateway
WML-enabled catalog that supports OCI

You have configured your Web server to handle the MIME (Multipurpose Internet Mail Extensions) types required for WAP. These are as follows:

File extension	MIME type
Wml	text/vnd.wap.wml
Wmlc	Application/vnd.wap.wmlc
Wmls	text/vnd.wap.wmlscript
Wmlsc	Application/vnd.wap.wmlscriptc
Wbmp	image/vnd.wap.wbmp

If you have your own Web server, you define the MIME types using the Web server's administration tools. In Microsoft IIS, you have to enter the types on the Properties page of your site on the tab card HTTP Headers. If you are not using your own Web server, inform the administrator or provider running the Web server.
