Transferring Stock from one Stock Code to Another
If you mistakenly received an incorrect stock code from an Australian supplier as part of an invoice which had a number of other (correctly entered) stock items you can either reverse your whole receipt or just use the Jiwa – Inventory – Stock Transfer to move the stock using the "from Part No" to "To Part No" facility.
Don't forget to save and activate your entry.
Note I am assuming that the costs you entered into the supplier invoice was correct for the part you thought you were entering in, not the part number you mistakenly entered.
