Unable to set or update the StatisticalCode of an Item

[kiiiiiiiii]

Hi,

I'm encountering an issue when trying to set the StatisticalCode field on an Item:

• When creating a new item, the field seems to be ignored or not taken into account.
• When trying to edit an existing item to update its StatisticalCode, it doesn't work either.

Did I miss something or is there a specific configuration required?

Thanks in advance for your help!
