Integrating Web Dynpro for ABAP into ABAP Workflow

Question

We have a requirement to create a User Interface via Web Dynpro for ABAP, and use that information to start off a workflow, transferring the data from the Web Dynpro application into the container of the Workflow.
Also later in the workflow, we would like an approval step to invoke a Web Dynpro that displayes the data, and an approve/reject button to be pressed that feeds that data back to the Workflow.
Has anybody done this, or does anybody know how to do this? We do not have the possibilities to use CAF in this project yet.
Kind Regards,
Tony.

Hi,
This is of course possible. Starting the workflow with Web Dynpro or from classic ABAP dynpro doesn't really differ. Just build your web dynpro as you would build a transaction, and from the submitting/execution phase, you just launch the workflow. Launching the workflow can be done with couple of different techniques (=function modules) and it has been discussed many times here.
Also the approval part shouldn't cause any problems. Just build an application which takes as a parameter for example the work item ID (or any other relevant parameter that you can imagine, which you can use to retrieve the needed data that you want to display). Then from the web dynpro application you can call for example a function module, which can complete the work item. Or another option is that you will raise an event (again with a function module), which your approval task is waiting for.
Once again, it isn't really that different from classic dynpro (or any other technique) - the same approaches can be utilized.
