Data loss if mandatory fields are not set

[Sangi0]

We have added a check before saving the product, which is the presence of the inventory.
As you can see from the video, if Vendors forget to add the inventory they are warned, but in this case they loose all their listing.
Draft/autodraft doesnt work in this case.
