Completion of workitem for webdynpro abap application - 2

Hi,

i start a webdynpro abap application from a workitem with BO WEBSERVICE, method PROCESSDIALOG. Terminating event is COMPLETED from BO WEBSERVICE.

After i complete the workitem with FM SAP_WAPI_WORKITEM_COMPLETE in the webdynro application, workitem is processed, but workflow is set to error.

error message:

Work item 000000400230: Object FLOWITEM method EXECUTE cannot be executed

Error when defining successor for node 0000000036

Error during result processing of work item 000000400232

Error when defining successor for node 0000000036.

When I execute the BO sepearately, I get an exception, " url_creation_failure "

I have gone through the below link. The thread is answered, but I could not find the solution.

Can any one suggest me the solution for this.

Thanks

Sai.
