Local Reference Data
The contents of local reference data files should be checked to ensure that all appropriate data mappings have been made between local and LLWR codes.
The Date Active From and Date Active To fields are available for all LLWR reference data (including local), to enable dates to be recorded as per the LLWR user manual. This is intended to help cross-check against values which have been retired from the collection.
This applies to the following local reference data:
-
LLWR Domicile (local) (LP08)
-
LLWR Ethnic Origin (local) (LN17)
-
Primary disability and/or learning diff (local) (LP30)
