# Troubleshooting

# Duplicated serials

Usually this happens because serial was programmed before creation in ERP:

Solution:

Download calibration files from serial without selected product:

**Solution**

<p class="callout info">Looking at the blade file, we found the problem was with serial on sale order.</p>

The problem was, the serial **DB20119714** was not added on order sale item with "**Link existing instrument serial number**" button.

The serial was not found, because the product of sale order item was not listen under "**Configurator data**" section (**Eligible products when enter serials input**)

of the **SER.0000001.000** product. Once added, the serial was shown in the drop down, could be selected and then linked to the sale order item. After this, the print displayed the correct data.
