The warehousing application we use reads the barcodes from "item Identifiers" as opposed to "GTIN" i guess this makes sense as you could have the same product with different units of measure that each carry their own barcode.
However i go to...
Item > Actions > Item > Identifiers
... and "Edit in Excel" and it lets me bulk edit the identifiers. However this only works for a single product as the "item_No" field is a "Read-only" column?
Code | Item_No | Variant_Code | Unit_of_Measure_Code
Is there another way to bulk do this, as it would be crazy to do this for each product manually?
