filter crosstab ds_1 to bar chart ds_2

Hi,

is there a chance to send the drill down + plus or - minus?

crosstab had a datasource_1 hierarchie with four  measure (columns).

In the bar chart i need only the

in the crosstab i need all measures

parent/child                    acmon       lastmon          w1          w1

+ Umsatzvermögen     120.00          140.00          11          9

parent drill down 3 childs

- Umsatzvermögen     120.00          140.00          11          9

       1.child                    40.00            40.00           5           2

       2.child                    40.00            50.00           3           4

       3.child                    40.00            50.00           3           3

when i datasource_1 bond to a bar chart then the bar chart show by closed parent the first line and open parent the 3 childs that ist OK but i need in the bar chart only the first measure acmon and lastmon. My idea copy the datasouce_1 to datasource_2. Hide the last two measures in datasouce_2 and bind it to the bar chart.

When i drill down (click plus parent) what filter i need from datasouce_1 to filter setting datasouce_2? the tech. parent/child is A000036

Thanks for any help or idea
