Thanks a lot for this quick answer.

...Good news.
After that, it is not possible to create a pack, a serial or configure an HikaSerial plugin in the front-end
...After some thought, perhaps using Hikaserial is not useful for my client, because he is just looking for a unique number / identifier
per order, NOT per product. => the order number (or invoice number) is perhaps such a unique identifier ? Am I right ?
Thanks again.

PS : I have another question, but it's about Hikamarket only (search capabilities). => First I have to look for an answer in the forum, if I am happy to find one (...and anyway this is not the right place).
