Hi experts.<BR>
<BR>
I am starting my WF through the SAP_WAPI_START_WORKFLOW in SE37.<BR>
<BR>
My WF consistst of a decision step with a secondary method, amodal method, which calls a custom method (call_url).<BR>
<BR>
The method call_url has been tested in SE80 and in WF with synchronous dialog chain(BMWP) where it works fine. <BR>
<BR>
Since UWL doesn`t support Synchronous dialog chain, I need to make a workaround.<BR>
<BR>
<BR>
Problem:<BR>
<BR>
When I start the WF and enter MSS to open the workitem, I can see the attachment (call_url method). However, when I try to click on the link for the attachment (which is going to execute my custom method) I only get an errormessage.<BR>
<BR>
The errormessage says: <BR>
"An error has occured during calling attachment. Try again and inform the system administrator about this problem".<BR>
<BR>
I have been checkin SU53, it is not an authorization issue.<BR>
<BR>
I have been reading Gatlings blog about secondary methods and searching the web about the issue with no luck.<BR>
<BR>
Any ideas how to solve it?<BR>
<BR>
Thanks in advance.<BR>
<BR>
Best regards,<BR>
<BR>
