RSWWCOND does not consider subcategory 001?

HI,

A customer workflow includes an activity with a condition to complete the workitem.

When I create a workflow instance, this wokitem gets status "waiting", because the requested start is a few days in the future.

But before the requested start happens, the condition to complete the workitem is fulfilled.

Actually I expect, RSWWCOND will complete this waiting workitem. In dubugger I could determinate it selects my item, an entry in table SWW_WIREGISTER exists. But the reports does delete the entry because the subcategory NE '002'." My workitem is of subcategory '001'.

What is the meaning of subcategory, and why is 001 not in scope for this report?

Thanks for any hints...

Jochen
