Changing the Default Browser Detection

1. Application parameter WDALLOWEDUSERAGENTS

If you want to specify that users can only run Web Dynpro ABAP applications in browsers supported in PAM, use application parameter WDALLOWEDUSERAGENTS.

More information: Application Parameters and URL Parameters

2. Implementation of a Business Add-In (BAdI)

A BAdI allows you to activate specific browsers to run applications in. This also functions for browsers that are not recognized by Unified Rendering browser detection.

Follow the procedure below:

1. Implement BAdI WD_BADI_USER_AGENT_DETECTION, and create BAdI interface IF_WD_BADI_USER_AGENT.

   For more information about BAdI implementation, see Business Add-Ins (BAdIs).

2. In the BAdI you can change the attributes of the two parameter groups, lightspeed_info and user_agent_info. You can parse the user agent string yourself and change the browser settings. The tables below describe the attributes and their values.

   • Attributes of lightspeed_info

     Attribute	Data Type of Attribute	Description and Possible Values
     supported	abap_bool	X for supported: Browser is fully supported X for tolerated: Browser is not supported by PAM, but is tolerated anyway. No value for supported or tolerated: Browser is neither supported nor tolerated.
