The Method CombinedReportAll enables access to the entire data set stored on the WMTP. A record transfer is defined within this specification as a transfer of a “copy” of the records and not a “move” of the records because the server retains the original log entries. The signature of this Method is specified below.
Signature
CombinedReportAll (
[out]WMTPOutputDataType[]CombinedReport
);
