The scenario is like this :-
We have prepared a Service Purchase Order for which service entry sheet, invoice verification and payment has been processed in the system with service tax @ 2.06% in june 2008.
But due to change in the service tax rate, the vendor has made an additional demand of service tax @ 4.12% on the SES process earlier. Hence we have to pay him a difference amount of service tax.
Can anyone suggest how to process this in MM.
Thanks in advance.
