Execute reserves workitem (was: work items getting reserved)

[Breslavets, Sergey]

Hi Michael,
 
normal status flow (happy path) for the dialog workitem look like this:
READY -> SELECTED(RESERVED) -> STARTED(IN PROCESS) -> COMPLETED.
 
the processing logic for a workitem is a little different on the web. If you are
executing your workitem from web inbox (transaction BWSP), control is NOT passed
to the function SWW_WW_EXECUTE which normally calls object method to process the
workitem. Instead, the ITS service associated with the web transaction for the
task is called (BWWF_WI_DECI for user decision) - this ITS service drives
execution of the workitem.
Since the function SWW_WW_EXECUTE (which is normally responsible for changing
the workitem status from "RESERVED" to "STARTED") is not called when the
workitem is executed from the web, the status is left unchanged as "RESERVED".
 
Also, you can change appearance of your user decision on the web by setting your
using a custom task/ITS service for the user decision step, or customizing ITS
service for workflow inbox altogether (copy service BSWP to e.g. Z_BWSP and
modify) - that's what we did for our implementation.
 
regards,
sergey

Hi Sergey,
I'm afraid I'd have to disagree with you. When a user executes a
decision task it's status normally changes to STARTED (at least it does
so for quite a few other decision tasks in our system). If the user
backs out, it remains STARTED.
Perhaps there is a difference in SAP versions - I'm working on a 4.6c
system.
 
The other curious coincidence is that this particular task will not
execute in a full screen, so I'm all but convinced that this behaviour
is linked.
 
Thanks for your input though!
Cheers
Mike
