When i use createOrReplaceInventoryItem from my application for an account that has a subscription, i get an error regarding manufacturer even though i indeed add MNP and Brand.

On the other hand when i do the same request for an account that does not have a subscription, the item gets created without any errors.

Does the fact that one request is for an account with subscription affect the createOrReplaceInventoryItem call ?

Do requests regarding accounts with subscriptions need any additional actions ?

Got any tips ?
