wrong Invoice number format derived from order

-- HikaShop version -- : 3.1
-- Joomla version -- : 3.7
-- PHP version -- : 7.1

I followed the instructions for the "Order number format" at www.hikashop.com/19-documentation/hikash...hikashop-config.html but it gives unexpected results for the "Invoice Number format". My "Order number format" is: My "Invoice number format" is: That results in the expected 00000380617 for the order but in the unexpexcted 38i for the invoice. Why is it not taking the entire order_id into account?

Hello,

I'm afraid the results are correct.
Please do not mix up "order id" and "order number".

Regards,

Ok, so I mixed it up. Now how do I get the desired invoice number "00000380617i"? Thanks

EDIT: I tried but the variable order_number does not seem to exist.

Hi,

You need to use that format too for the invoice number format: {id size="7"}{date format="my"}

Now {order_number} should work too unless the order is being created as already confirmed and thus the order_number is not yet set when the invoice number is generated in that particular case.
