You have to segregated the amount as per the Hsn then make total of bill a+b+c =d
Like that you segigate all and then reconcile with the total amount your segregated and bill total same or not in excel first
Then file the segregated amt in portal with same bill no and date only different HSN code and amt and you're new total invoice amt after segregated
