Negative sign in Front of Currency Field

Hi Experts,

I am facing one problem in displying the amount in currency field on ALV Output.

My requirement is to show the - Sign in front of the amount i.e. field name BSEG-DMBTR but I am not getting the -ve sign in the table

Based on Debit and Credit indicator I have to show the -ve Sign in front of amount field for example  I want to shown the amount field like '-1234.56'

Thanks in advance for your help
