CIF Header
The CIF Header record (HD) occurs at the start of the file and provides information such as when the file was generated and, for update extracts, the file reference of the last file that was processed. This is important, as CIF update extracts must be processed in order, as they are effectively set of changes since the last extract generated for a particular profile.
