Error A product with the same code already exist

I have first searched the forums before posting. I have found the problem listed, but in the context of exporting or importing product information in CSV files.

My problem is with a routine addition of a new product, with a variant.

I have one product variant: shoe sizes.

If I create a new product with a product code, and add the variant, the shoe sizes are added to the product codes as s suffix, but with to the wrong size. So in the table, I would see [productcode]_33 for shoe size 17.

That requires that I do it manually. That's OK, we can deal with that, although I wish the size would match the addition to the end of the main product code.

The real big problem is this: When we try to add the products we started getting the error "a product with the same code exists."

I deleted all the ones created automatically and just tried to just add each variant manually - one by one. Same problem "a product with the same code exists." Even when that's not true.

I ran the Hikashop database check. No change.

So I am stuck and cannot help the client add product.

I keep deleting and re-adding product. No luck.

I did not see duplicates in the actual mysql database either.

Any thoughts?

You have always been patient and helpful and I thank you in advance.

With kindest regards,

Nadine
