Buyers, like for example some marketplaces, might require models to be mapped towards categories as a first step in the validation process.
The reason for that is that each category could have different requirements regarding what data to be needed, or what data to be mapped.
For example, a buyer might require more information for models mapped to a category called "jacket" than for models mapped to categories like "shirt" or "trouser".
After the first validation of a publication towards a buyer requiring model mapping, validation error regarding model mapping will be shown.
When models has been mapped, the publication should be re-validated to see if any further data mappings is required, and/or any data is missing.
In the example above models mapped to category "jackets" has received validation errors as the buyer require "season" and "materialPercentage" to be uploaded for models mapped to that category.
