Where to change automatic number prefix? still cannot find in Form Default

Dear Sir,

May I know where to change the automatic reference number prefix in Sales Invoice?

I could not find it in Form Default. The earlier set the automatic reference is wrong and I need to change it.

Thanks.
Regards,
Sandy

There is no automatic reference number prefix in Sales Invoices or anywhere else. If your business has prefixes, those must have come from a custom theme. You would need to modify the theme code. But custom themes are considered obsolete features. They still work for the time being, but will eventually be removed from the program.

I think you should ask yourself whether prefixes are really necessary. Transaction forms are all labeled, and the reference is clearly marked as such on the face of the transaction. Is it necessary to have a sales invoice, for example, that is prominently titled as such, carry a reference number like INV12345? Where is the value in that?

Hi, how about changing the automatic number ?
Thanks

Just change it - the automatic reference number is always created as +1 to the highest existing number

You can also change prior reference numbers with Batch Update.
