If listing belongs to more than one category, the second category must also support multi-variation listing.
Listed product must meet the next condition (If at least one of the condition is not met, Bundle, Configurable and Grouped products will not be listed; Simple with Custom options product will be listed as a simple product without variations):
The quantity of product variations is not more than 5.
The quantity of values of each variation is not more than 60.
The sum of quantities of all possible products combinations is not more than 250.
