I have some products which are out of stock. I have marked them as not for sale/not for purchase.
I no longer need the products in dolibarr so i need to delete them.
The delete button is disabled and on mouse over it shows “product is used”
You should delete all datasets which refer to the product first.
Otherwise you (say) want to look up an old order - BUT your request could not be fulfilled, because the pointer to the product in this order is “dangling” (going nowhere).
