Hi everyone,
I am using Import Scenario to create Item Classes with Multiple Attributes, and this Import Scenario works:

But we need those attributes to be as variant so we define each attribute category as “Variant”.

But after Preparing and Importing, it fails with the error:

Can you please help how to set a multiple attribute with variant as category for Item Classes in Import Scenario? Thank you so much
PS: Some records we are importing has single attribute, others has 2, 3 or more
