Currently I have the Product Key setting in Tracking Manager set to SKU.
However, it would be great if you can add the parent SKU variables to the rows in the cart_product_list object on the cart page along with the child SKU which is currently being added.
In the end, it would be ideal if the following 3 types of SKUs were added to the cart_product_list object rows:
1) Product Attribute Combination SKU
2) Simple SKU
3) Grouped SKU
Our catalog utilizes all 3 types of SKU's depending on product, so if any are unavailable due to catalog setup, then that value can be empty string.
Essentially some of my tracking needs require the parent SKU.
I'm running up against a migration deadline - would be awesome if this could be done in next week or two.
Let me know if any questions.
