Hi

In Zoho Books, as regards to Credit Note. From Invoice, when we create a new associated Credit Note, is it possible to copy the Invoice Number into the Credit Note Number field?

For example the Invoice number is 2021-003 (where the suffix "003" is auto incremented) with every new invoice.

When we create a new Credit Note from this invoice, we would like to copy 2021-003 into the Credit Note number for editing. Currently the mechanism of Auto-incremental of suffix value for Credit Note can't be linked to Invoice Number, as it seems it is a standalone incremental.

Is this possible or a possible custom function exist for this?

Many thanks
