Performance problems / slow response times with high volume w orkf lows

[Alon Raskin]

Hi Peter,
 
We had similar problems on one of my old projects. The problem was made worse
by the fact that the users had dynamic coloumns configured in their inbox. I
debugged the Inbox code and found that sap would instantiate a new object for
every coloumn even though the attributes/coloumns could be derived from the
same instance.
 
What we ended up down was write a custom report which replicated the
functionality that the users required (Forward, Resubmit, Execute, etc). The
report was tailored for a specific workflow which was the main culprit. It was
much more efficient the then Inbox because it was not generic.
 
I do agree with Alan though. You may want to ask yourself why every user has
thousands of Work Items in their inbox? Are they overloaded? (i would say yes).
Perhaps you need some more agents to Work the inbox.
