If you receive the following error message when trying to import wear results via the Edit Wear Measurement screen, try exporting a spreadsheet first. The reason is that a new "Ref" column has been added to the Results table to allow the collection of pipe wear data.
If you normally import results rather than entering them individually, and if you have a spreadsheet set up to do this, you may receive the error message above. You can add the "Ref" column into your existing spreadsheet, but the recommended method is to use the Export Data button as shown below. In this example, you will receive a blank spreadsheet with the header rows correct and ready to be imported back in. An example is attached, which can also be used if you prefer.
