Hi,
This option will work only for local connections.
Using a local connection, when connected to SAP NetWeaver BW InfoCube, the BW Reverse Sign
property is now taken into account when you select a dedicated option.
In BPC reporting for Account type INC and LEQ will be shown in reverse sign. It means if the values of these accounts are -ve in back end then in the reporting it will show as +ve.
In your case this option will not work. What you can do is, refer property of the account and convert sign in local member to meet your requirement.
Hope it helps...
regards,
Raju
