If analytical accounting is managed in the folder, it is necessary to define the way in which the analytical dimensions are initialized in the header and in the invoice lines coming from the service request.
This definition is made via the setup of the default analytical dimensions.

SEEINFO If a product is associated with an account that is tracked analytically by a nature and no analytical dimension exists in no axis on the invoice line, the system will refuse to validate the invoice.
