Functionality
The function module determines whether there are work items in theBusiness Workplace of the specified user, and if so how many. Thefunction module takes active substitution into account.
To determine the number of work items, the function module calls theuser's worklist. If you have already called the user's worklist by analternative means, for example, by using SAP_WAPI_CREATE_WORKLIST, SAPrecommends that you determine the number of work items from the worklistinstead for performance reasons.

Description
This import parameter is used to control the level of detail the resultis to have. The parameter has a considerable effect on the performanceof the function module.

Value range
0,,The check is only to establish whether there is at least one workitem (parameter WI_COUNT = 0 or WI_COUNT > 0). It doesnot tell you how many work items are actually in the BusinessWorkplace. Nor does it establish how many work items there are for atask (not even for the established work items).
