Hi @thibaultb473199 , Does you instance has any Business Unit created?
If yes, then look for table 'business unit' and add new BU names
there.If not, then you need create one schema where you can enter names
of different 'business unit'. Also, each recipient will be associated
with one business unit, so create link between 'nms:recipient' &
'businessUnit' tables. Thanks,Jyoti
