At the beginning of N+1, you must declare the quantities placed onto the market for year N corresponding to the validated styles in phase 1.
Refashion will send you the list of validated styles for the different types of eco-modulation and for which the sales figures must be declared.
The declaration of the quantities for eco-modulated styles will be done through an excel file to import on the extranet.
For more details, please consult our eco-modulations' guide.
