Why can't I click “Next” when the product import shows “0 items ready to import”? Do errors prevent me from continuing?

1. In “Review and Correct”, first check whether the system displays “Data processing is not yet complete: Comparing existing products in the system N/M. Import will be available after the comparison is complete.” Data still being compared is not yet counted as ready to import, so seeing “0 items ready to import” at this stage does not mean the data contains errors. Wait for the comparison to finish. 2. Once the comparison is complete, you can click “Next” as long as there is data ready to import. You do not need to fix all errors first. In this test, 886 items were ready to import and 93 items were marked “Has Errors”, and “Next” was still available.
