Description
Many sites sending PV files send files even if the content is unchanged. This puts a tremendous load on the UKRDC which would only increase it also has a significant impact on the log data file sizes. To help alleviate this the file deduplication routines check to see if the received file is essentially unchanged from the previously received file for the patient from the sending unit. If it isn't then it is not passed on. There is a connection in place to deal with files being rejected due to lack of PV memberships so that files will be allowed through after the program membership has been created on PV even if the next received file is flag as duplicate. There may still be a need to back load older files.
