TOAD for SAP Error: Character set conversion

Hi all
I have this Error MSg:

Character set conversion is not available between client character set ‘iso_1’ and server character set ‘iso15’

sp_configure ‘enable unicode conversion’

enable unicode conversions 1 0 0 0 switch dynamic

What database you connect to? For ASE, Please change CharSet to iso15 see if it make difference.
