I need to replace the A column values with the I column values. Both tables have barcodes, all barcodes are unique because it identifies the product codes. But the two tables will have a match e.g. A1 is same as I1 becasue E1 and K1 are same barcodes and that is the same product code. Left column is just old version of product codes and the right one will be the new ones. Thanks
