Linking an excise supplementary invoice to multiple invoices in Release 5.x

The provision to link a supplementary invoice to multiple invoices has been removed in Release 5.0 as it was creating calculation errors while filing returns.

If supplementary invoice is linked to two separate invoices created during different return periods, then the invoice value will reflect in the returns filed for both periods. This will result in filing wrong returns.

To avoid this error, supplementary invoice framework has been changed to link to a single invoice, and not multiple.
