Problem Analysis: All Web Dynpro Applications Have Status STOPPED 

If you get the message that all the Web Dynpro applications have status STOPPED check if the Web Dynpro service, that is the Web Dynpro runtime environment, is correctly deployed and ready for use.

Check the service via Telnet: Enter the activating command add deploy, next command lss (abbreviation stands for “list services”). The list should contain the entry webdynpro for Web Dynpro, and the corresponding status should beSTARTED.

If this is not the case, the Web Dynpro runtime environment was not correctly installed. If this is the case, check the status of the system applications, which must always exist. Using command list_app you get an overview of the applications currently deployed. The list should contain sap.com/tc~wd~dispwda, and the status should be STARTED. If this is not the case, the Web Dynpro runtime environment was not correctly installed.
