What data in included in the export?
The data is updated once every 24 hours, at 05:00 GMT, so may not reflect the most recent changes from the current day.
The CSV export will contain the requests made in the last three months by all of the users in your organisation.
Please note that in rare cases, the price of resources shown in the export may be subject to change once the fulfilment process is complete, and therefore may not always match up with what you will see in your Breakdown of Spend report.
