Dashboard to webi data duplicate

Hi Expert,

I have developed few dashboard which is of to access the webi report from it.

Functionality:

1. User will select the respective cost centre, FY and posting period.
2. The key value will be passed from dashboard to refresh the webi report.

The issue is that the CostCentre infoobject has been marked as key and text display in RSA1, so while passing the CC key value from dashboard to webi it cant able to fetch the required CC and it leads to data duplication.

Please help me on this and let me know if you need any further information.

Version BI 4.1 SP05 and Xcelsius 4.1 SP05

Regards,
