I uploaded 4,000 skus with an "as-of-Date" sku date of 10/1/21 as type "non-inventory". I know see that invoices can't access those skus unless the invoice is after the 10/1/21 "as of date", further that in the skus loaded the sku has the date as "start". How can I change the Start Date, in bulk (4,000 skus). The import will not allow a "as of date" prior to the 10/1/21 from the prior import. Is there an inventory adjustment import like I would use on an annual inventory?
