    Additional information

    XJACS201 is derived in both the Student record (Cyy051) and AP student record (Cyy054). In the Student record it sits on both the Cyy051_SJ and Cyy051_CO tables, created from the XJACS01 and MODSBJ fields respectively. In the AP student record it sits on only the Cyy051_SJ table, created from that record's XJACS01 field.

    Please note: XJACS01 on the _SJ tables differs from MODSBJ on the _CO table in that the former field permits the return of generic subjects (those ending in '000'), whilst the latter does not. Valid entries A0, B0, C0, D0, F0, H0, K0, L0, M0, N0, P0, Q0, V0, W0 and X0 cannot be derived from MODSBJ as a result.

    From 2012/13 the underlying JACS subject coding frame adopted the JACS3 subject codes.

    Revision history

    Date Version Notes
    2016-06-16 4.2.1 Field length reduced from three characters to two, which aligns with the format required for the output. No change to function.
    2014-10-16 4.1.3 Additional information section amended to allow for the use of this field in the Cyy054 AP student record.
    2013-01-17 4.1.2 Minor typographical edits to four valid entry labels for consistency with other labels. P0 and V0 now use an ampersand rather than 'and'. C9 and I9 now use lower case throughout. D0 label amended to include 'veterinary sciences' to more accurately reflect the content. No change to meaning.
    2013-01-17 4.1.1 Amended to reflect changed codes and labels in JACS3. Deletion of technical specification stage that specified the remapping of G010, G020, G910 and G920 as these codes are not included in JACS3. ZZ is no longer a valid entry in this field.
    2010-04-09 3.1.3 Additional information updated to describe where this field exists, and to make explicit reference to mapping in technical specification
    2009-07-17 3.1.2 Clarification of use of 'G0' and 'G9' in Additional information
    2009-03-13 3.1.1 New output values of G91 and G92 added. Format changes. Field type added
    2008-07-26 2.1.2 Typographic error corrected - amend reference in technical specification from _FTE table to _CO table
    2008-05-14 2.1.1 Amended to reflect changed codes and labels in JACS2, including new output values of G01 and G02
    2008-01-01 1.2.1 Amended to reflect 2007/08 record structure – now refers to Cyy051_FTE table. Added R8 – European Studies, remove G9
    2007-02-06 1.1.2 Changed to allow XJACS201 to also be calculated from SBJ on the _CO table
    1994-01-01 1.1.1 Created
