  Modify the Layer Type: If you have access to the backend, you can try to change the layer type of the variant to 'customer_base' using transaction codes like SE80 or SE11, depending on where the variant is defined.
  Recreate the Variant: If modifying the existing variant is not feasible, consider deleting the problematic variant and creating a new one with the correct layer type.
