Hi @Glenn_Amazon,

I'm still having issues with editing my product packaging dimensions, specifically Item Package Length, Item Package Width, Item Package Height, Package Length Unit, Package Height Unit and Package Width Unit.

I created new SKUs with the same ASINs because we recently changed the packaging dimensions with our newest order. The new SKUs transferred the attributions from the older skus and have been locked.

As suggested by Brand Registry Support, I uploaded an inventory flat file with "Update" selected, not "Partial Update." The upload was accepted successfully, but the old attributions were still locked. I was then told to wait 48hrs for the new flat file changes to take place. After 48hrs, the attributions were still locked and un-editable even if saved with the new values. I have done this process twice already within the last 1-2 weeks because I receive the same automated suggestions from Seller Support.

Case ID 13594992801

Spreadsheet Upload Batch: 187669019591

Can someone from the backend change these attributes for me? I have tried everything suggested by Seller Support.
