When trying to upload your Census XML file into COLLECT, you may receive this message: An error occurred uploading the file. Please contact your system administrator.
It will include a line such as PartnerUKPRN, value= _ for LearningAimsOnRoll and a message saying something such as Unable to convert or Input string was not in a correct format.
This error appears when the UKPRN has been incorrectly set to a figure that includes non-number characters and/or is not 8 characters long. Correct the UKPRN following these instructions.
Once you have corrected this, regenerate your census. Download your census again and re-submit the new file.
