I'm running Magento Enterprise 1.11.2.0 and my inventory is primarily shoes. I use 3 store views: EU, UK, and US. My size attribute across these 3 views allows me to specify equivalents for each regional sizing convention.
Some brands have slight variations in only one or two regions.
EXAMPLE: Brand A: UK 7 | US 8 | EU 41.5
Brand B: UK 7 | US 8 | EU 41
Brand C: UK 4 | US 6 | EU 36.5
Brand D: UK 4 | US 6.5 | EU 37.5
If I create an attribute label for each variation then when I am in the store view for a region that does NOT have a variation, the sizes repeat themselves in the layered navigation because Magento sees each attribute label as discrete.
EXAMPLE: A category page with only 1 item from Brand A and 1 item from Brand B viewed in the EU store is fine, but viewing the UK store displays layered nav like so:
Size:
UK 7 (1)
UK 7 (1)
Ideally this would display as:
Size:
UK 7 (2)
Any help strategizing would be greatly appreciated.
