What exactly is the SKU

I checked 1.2.0 and the SKU field is added to the products. I don’t really know what it is or why we need it (and certainly: why is it a required field?).

We do have the product name, why do we need the SKU field? Can’t this be autogenerated if it’s really necessary?

Edit: I sell services so you can imagine the need for an SKU is really not there… Would be great if it weren’t required. :wink:

It’s basically a unique identifier. Take a look here:

I don’t think it’s a good idea to be autogenerated, as many products came already with their own SKU.
I agree it shouldn’t be required, but this gives you a great chance to tidy up a little bit your services :wink:

For your info: I changed application/modules/products/models/mdl_products.php and looked for SKU and set the rules ‘required’ to rules ‘’. This works for me.
