Gretings, I am having issues changing prices using file exchange, I download my file CSV & open in Excel (also tried open office ods), change the pricing in the speadsheet. I change the item number from "scientific ?" format back to a number (no decimal places) so that it looks like an item number. I save the file again as a csv file & upload. I am continually get the following message "Error - Input data for tag <Item.ItemID> is invalid or missing. Please check API documentation.|Item.ItemID|" I have a mixture of single line items (each with it's own ItemID) & some listings with variants which all fall under the one ItemID. The Error codes Reference does not cover this. Any advice / guidance would be appreciated.
