Invoice number is auto generated In Finance module.
We want the invoice number to begin from number 01 in each new academic year.
Please guide us how to solve it.

Unfortunately, the way invoice numbers are programmed, they are tied to the incremental database ID for that invoice, which must always be unique and cannot repeat. There is a notes section attached to each invoice, I suppose if you wanted to create your own invoice numbering system, you could add it to the notes to each invoice, but this may not be ideal and wouldn’t be automatic.
