DESCRIPTION: This field contains the internal batch identifier that was used during the generation of the batch message.
The Control ID of each individual message included in the batch is constructed from the value of this field and a sequential number separated by the '-' character.
TECHNICAL DESCR: The INTERNAL BATCH ID field is automatically populated with the identifier of the batch placeholder created by the CREATE^HLTF procedure. See the $$CREATE^RORHL7 and $$TMSTMP^ROREXTUT functions for details.
The actual batch control ID (BHS-11) is usually different from the value stored in this field.
