This idea has been merged into another idea. To comment or vote on this idea, please visit PL-I-446 Bulk delete for products, variants and data.
If we would like to delete variants there are no other way currently then to select in the pim and click delete.
If there are many variants/products to delete this is very time consuming.
IDEA:
Make it possible to delete all products from a product list.
In that way you could easily filter out the products you want to delete and save that as a product list and then add an action to "delete all products in this product list form the PIM"
