General - How can I be sure that my data is submitted/sent to the Commission?

When data is sent to the Commission, the sender receives an automatic notification from SFC2014
On the search screen list of Programmes, Payment Applications etc, and in the 'General' section of the object under 'version information', check that the "current node" column is "Commission" and the "status" is "sent".
In each object (excluding Standalone/referring documents) a snapshot document is added to the 'associated documents' section of the object.
For single documents, check that the "sent date" is not empty.
