Process how to delete a document reference (NB: you are not deleting the original document, just the referencing link).
Go to the Documents section and click the 'Import documents' button to the right
Click the 'Download template' button under the sub-heading 'Import document references'
The downloaded Excel sheet will include a new column called 'Delete'
The default input is set to False (i.e. not to delete the document reference(s)). To delete a document reference, please select the input True from the dropdown list in the relevant cell. Save the Excel template
Upload the updated list and the system will run a scan on items to be added as New (N), Updated (U) or Deleted (D)
Submit the template and the stated document references will be deleted / un-linked to the relevant valve
TIP: if you have a lot of valves (hundreds or thousands), you can delete all the 'not needed lines to be checked by the system' in the Excel file to be uploaded. The system will then be able to run the check much faster by going through only a few lines, rather than all of them in the spreadsheet. In the example above, when I want to delete only 3 document references - then the Excel sheet could look like this with only three rows to be uploaded and checked by the system
