prestashop. What is the "Show all IDs" option in Import Products for?

Question

Prestashop

I welcome everyone! Despite the description, I don’t understand what exactly this function does c2n.me/3xAUtEi ? "They will increase automatically by 1", they are like autoincrement, so they increase automatically by 1, why then this option?

Answer 1

Incorrect translation. When importing, you can either use the ID from the imported file, or regenerate the ID. In the first case, new products are not created, but those that already exist with the same IDs are overwritten. In the second case, new products with a new ID will be created.
