Base Language in Create New Company

Hello,

when a user create a new company from BO application, he can choose in the creation form several parameter (name of the db, local settings...) and also the language in which the default data will be added (like the default status of the service call)

I'd like to know if the data is stored somewhere in a table (in SBO-COMMON or in the created comapny).

I need this value to add the own default data of my add-on in the specific language.

Someone knows where I can find this information ?

Thanks a lot for your help.
