Hi,
Have you checked for some SCN blogs on this topic?
Here are some of the basic ingredients you need to get Workflow and Webdynpro to play together nicely:
- the execution of a dialog workitem triggers a Webdynpro application (configured via SWFVISU)
- the workitem id (WI_ID) is passed to the Webdynpro when it is triggered
- the Webdynpro reserves the workitem, using SAP_WAPI_RESERVE_WORKITEM
- the Webdynpro reads the workitem container using SAP_WAPI_READ_CONTAINER
- the Webdynpro presents this information on the screen to the user, and also provides them with some buttons to push (NB you have to build these screens!)
- the workitem is completed by calling SAP_WAPI_WORKITEM_COMPLETE (or by raising a terminating event). You can also make changes to the workitem container using SAP_WAPI_WRITE_CONTAINER
Good luck! The first one you build is the hardest, but it's plain sailing after that.
I think Webdynpros are great for presenting workitems to the user - you can provide a lot of sexy contextual information to help them make their decision.
cheers
