Get runtime workitem ID

Wed Jan 5 03:23:27 EST 2005

I think the message below contains the answer to your question. I used it
myself to find out if a method is called from a work item

* Started from work item?
DATA:
  t_requester TYPE STANDARD TABLE OF swotobjid,
  l_workitem  TYPE swwwihead-wi_id.
FIELD-SYMBOLS:
  <requester> LIKE LINE OF t_requester.

CALL FUNCTION 'SWO_QUERY_REQUESTER'
     TABLES
          requester = t_requester
     EXCEPTIONS
          not_found = 1
          OTHERS    = 2.
IF syst-subrc = 0.
  LOOP AT t_requester
       ASSIGNING <requester>
       WHERE objtype = 'WORKITEM'.
    l_workitem = <requester>-objkey.
  ENDLOOP.
ENDIF.

Hi Alon/Darrell,
Interesting, these were the sort of hacks I was hoping for, but alas don't
play nicely in an attribute. I also found SWO_QUERY_REQUESTER, which - like
SWE_WI_GET_FROM_REQUESTER - gets its info from memory (under different
id's).
However the swo_%invoke at least told me why it won't work: The requester
in
the case of an attribute is the object itself, which kinda makes sense.
(Unless I'm missing something?). Argh, so close and yet so far.

Interestingly enough, the attribute gets invoked twice during the running
of
the workflow (once at startup, and once at container operation), so that
counters any performance hit I was trying to avoid. This is a bit of a
performance-intensive bit of code. I thought attributes were only evaluated
on an as-needed basis...? Oh, well.. method it is.

Thanks both for your input, it's fun to go digging around the internals on
occasion, but now Friday becons and I am getting too thirsty for this.

Cheers & happy weekend.
Mike
