8.7.2 MFN/MFR - test/observation master file

The usage of the OMx segments in the Master Files MFN and MFR messages is described in Sections 8.3.1, "MFN/MFK - master files notification," and 8.3.3, "MFQ/MFR - master files query," above. Basically the segment groupings described below follow the MFI and MFE segments in those messages (replacing the [Z...] section as follows:

MFN     Master File Notification     Chapter
MSH     Message Header        2
MFI     Master File Identification     8
 {MFE    Master File Entry        8
   OM1    General Segment (Fields That Apply    8
      to Most Observations)
[other segments(s)]
 }

where other segments can be any of the following combinations:

MFI-1-master file identifier code = OMA, for numeric observations

  [
      [OM2]  Numeric Observation Segment 
      [OM3]  Categorical Test/Observation Segment
      [OM4]  Observations that Require Specimens
  ]

or

MFI-1-master file identifier code = OMB, for categorical observations

  [OM3  Categorical Test/Observation Segment
    [{OM4}] Observations that Require Specimens
  ]

or

MFI-1-master file identifier code = OMC, for observation batteries

  [OM5  Observation Batteries
    [{OM4}] Observations that Require Specimens
  ]

or

MFI-1-master file identifier code = OMD, calculated observations

  [OM6  Observations Calculated from Other Observations
   OM2]  Numeric Observation Segment

Note: A test/observation definition may have both an OM2 (numeric) and OM3 (categorical) segment included in case the value may be either numeric and/or categorical.
