Actually we have two group of customers. Both are having ability to see different products. But in the product page at the reviews section, for both customers, for ratings they should be able to see the rating of both products compinely.
Main product sku is 'mainsku' -> it is for normal group of cutomers then Other product sku is 'mainsku_CGG' -> it is for special group of
In both products's rating. Customers should be able to the rating as combined and calculated percentage rating of both.
mainsku->100% rating mainsku_CGG -> 80% rating
So in product page rating should be 90% (Average of two), and number of ratings also should be get added.
I don't know how to change the ratings collection here. Can anyone help here?
