Writing an internal table to a WF container for an already triggered WF From Web Dynpro

Hello Margaret,
Yeah that's exactly the what i was trying to do which is to pass data from Web Dynpro to Workflow in the middle of the process. I was trying to avoid the FM SWE_EVENT_CREATE because i thought there should be a more intuitive way of passing an internal table to workflow. I've used the the method if_swf_cnt_element_access_1~element_get_value and I was able to read a structure so thought that if_swf_cnt_element_access_1~element_set_value should work for setting data as well. It didn't work for some reason. It could be that i'm missing something in the code i've pasted before. Someone has suggested that i convert the table into XML and do other conversions but that seems to be an overkill for something that i think should've been more straight forward to achieve. I did try the local event and it did work so i guess i'll stick with that for now.
Thanks a lot for the suggestion.Ali

While searching for this topic, most of the posts i found showed how to do it while raising the event via the FM SWE_EVENT_CREATE. The event container for this fm is swcont which is compatible with the macros. For example the following would work:

So instead i tried completing the work item using FM SAP_WAPI_WORKITEM_COMPLETE but that fm has the type swr_cont for its container parameter which is not compatible with the macros container type and hence it was dumping when i used it. Same thing for the FM SAP_WAPI_WRITE_CONTAINER.
