Problem with Reportfilter function in webi

Hi All,

webi 3.1 version

source sap bw cube-->data federator-->universe-->universe-->webi report

created webi report on top of universe, webi query filter contains 1.employee no ln list prompt

                                                                                                       2. start date of activity between (enter start date) and (enter end date)

webi columns like  region, workcenter, employee name, ...etc.,

dont have region obj in bw, we have created region obj (@prompt ) based on workcenter.

now, i have 3 employees 1.301(emp name :cat user 01)

                                         2. 302(emp name: cat user 02)

                                         3. 303(emp name: cat user 03)

each emp contains 2 rows of data 1 for billable and another for non billable., but client want to see in single row so applied =reportfilter function for both region and work center so data is coming in single for each row.

for 301 and 302 there is no region and workcenter data, having data only for 303

if i run individually 301 or 302 i am getting black cells for region and wrkcenter bcz there is no data

but if i run 301, 302, 303 at a time im getting the region and wrkcnter data of 303 to 301 and 302.

but 1st and 2nd row of region and work center should be balck, but it displying the 303 data to 301 and 302.

how to resolve this?

please help me on this..
