hi anil
you are getting this error because currency conversion ratio is not maintained in TCURF screen.
first goto T code OBBS and check whether you have defined the ratio for currency EUR & INR. Chances are that the conversion ration are not maintained. define the ratio (1:1 or 1:10 as per your requirement) and then go to T Code OB08 and give the currency rates eur to inr.
kind regards
