I created a marketplace with two fields: a "Store Reference" field that the store owner fills, a "SKU" field I want to be unique and generated automatically.
On Drupal Commerce I want the SKU of my products to be generated automatically and made unique.
I want a sequence of numbers and random letters, for example a single SKU of 12 characters (number and letter).
There is a hash token in "Explore Available Tokens" and "Random". What is it used for?
Can it meet my needs?
Can it generate a unique code that will never be reused?
There are several store owners who can create products at the same time; the same SKU must not be generated.
