One of my customer is looking for 'In stock filter' on category landing page in POS. Products are having different inventory dimension like size, color, style and configuration. I remember there was 'product availability' as a filterable attribute in Commerce website.
Can someone share details on how it works. As in Does it maintain separate view etc which keeps inventory at product level to enable filter in PLP. I don't want to call the service as many time as products (variant) belongs to a selected category.
