SWI2_ADM1 doesn't find all orphaned items!

[Michael Pokraka]

Hi all,
Aside from this may be useful info for the list, I'm also in a bit of a dilemma over this one, it concerns SWI2_ADM1 - workitems without agents:
 
If a user is deleted from the system his/her items are not always orphaned. Also, if a workflow still gets sent on to a user who no longer exists, workflow just sends it and SWI2_ADM1 will not report it. Effectively this item is lost without deadlines or other secondary monitoring.
 
I have reported this to OSS, and their reply was pretty much that there is nothing worng/they aren't prepared to change it - technically speaking the item has an agent - even if it's a bogus user 'DOESNOTEXIST'. SAP have recommended we clone the report behind SWI2_ADM1 or do other development to track user deletions and periodically 'clean up' the workflow tables so that SWI2_ADM1 will find everything it should.
 
The dilemma is that client is not too happy about what they think falls under 'doesn't do what it says on the box', and even less happy about maintaing more cloned reports than necessary - or having to manipulate SAP tables.
 
I would welcome any opinions you might have, as I'm ... well, I'll keep my opinions out of this for now. If you've encountered the situation and have a different workaround, I wouldn't mind if you could drop a hint either.
 
Cheers
Mike
