Hi! I use 1.7.7.2 and I have problem with my import:
I have products with combination color and size
All products with same color have the same index (reference) so for example if I have 10 sizes then their will have same index.
It is possible to have same index for this products - at the moment on import I only have imported one of each colors - it means presta takes index as unique.
Any idea how can we change this? It should be possible to have product with the same index ... ?
Index as a key is not selected on import so it must not be unique ?
