How do limitations apply to product variations?

For a product with combinations (product variations), the minimum and maximum quantity settings distinguish a shared limit from values specific to each combination.

In the module’s settings on the product editing page, the “Consider the variations as a single product” option lets you choose the scope of the values you enter:

• Yes — shared product limits: enter the product’s minimum and maximum quantities. The shared check uses the sum of the quantities of its combinations in the cart. For example, with a shared maximum of 5, 3 units of one combination and 2 of another reach the limit; 3 + 3 exceed it.
• No — settings per combination: enter the minimum and maximum quantities in each combination’s section. You can set a maximum of 3 for one combination and 4 for another: a cart containing 3 + 4 meets these two separate limits.

For these minimum and maximum quantity fields, 0 means no limit is set in that field. This does not describe batch rules.

After changing modes, save and reopen the settings to check the stored values. Test adding products from the product page and changing quantities with the buttons and input fields in the cart, using several combinations.
