Q: Is there an easy way to try Errored items in Sku Fetch again without starting over?
A: You can put check marks on the errored items and then click Move Selected to Draft.
Or
You can set the view on your item list to 100 items per page, type in the word Error into the search and click the Select All on Current Page button then click Move Selected Items to Draft. Then repeat on page 2 and so on if there are more.
Then you'll go to your Draft List tab where you can continue editing the items and finish processing.
