>So my question is : Is it possible to Link SAP Workflows and Web Dynpro Apps. Or can I pass values to Dynpro Apps From Email Inbox of a user.
The answer is yes.
This sounds like a simple scenario. If you have an ABAP web dynpro application, you will have an URL to it. Then you place this URL to the email that is sent for the approvers.
Most probably you will have some kind of key or ID for the data that is going to be approved. Let's say you are approving invoices, so your key is the invoice number. You can for example build your approval application in a way that it takes this key as an parameter.
An URL for an web dynpro application can be built dynamically with the help of method cl_wd_utilities=>construct_wd_url. (The URL should be built just before you send the email from workflow. The needed key information should be available in the workflow container.
Just make sure that you build your application in a way that security/authorization issues are well taken care of. It is easy to forward emails etc...
