Webdynpro and Workflow

Hi Experts,

               I have a requirement for creating webdynpro application and display business partner details into custom table using business partner number. And on displaying the business partner details. Creating a save button and on clicking on save button a workflow should be triggered. And in the workflow when the manager approves the workflow the business partner details should directly save into the custom table(Ztable).

Please can anyone suggest me some helpful answers.
