Showing wrong SKU for barcodes in the POS

Hi Team,

We have uploaded some item in to RMS for which SKU's data is flown to POS but not the bar-codes. So we deleted the SKU's in the POS and also disabled them in the ITEM_LOC (RMS System) table.Again we uploaded the items freshly  new SKU's were created and they reflected in the POS successfully.But already some order and transfers has been created on the old SKU's  so we just updated the ITEM_MASTER  table in RMS  like replacing the new SKU's with the old SKU's and deleted the new SKU's in the POS system only, disabled them at ITEM_LOC (RMS )table.
