Account Type Expenses to be shown as negative values in SAP EPM Report

Hi,

I want SAP EPM report to show only Expenses as Negative values. At present all the P&L statement having positive values(INC and EXP)

I tried the Formatting with Specific member/ property like Account.ACCTYPE = EXP and  formatted the data field as -10000. This setting is not giving expected result.

Is there any easy way to get all the expenses as Negative values based on the account property?

Thanks.
