  • Item 2.
    • In messages INR^U06 “Automated Equipment Inventory Request”, fields of the INV segment serve as filtering criteria. From the logical point of view, when no filtering on inventory item ID and/or inventory item status is desired, the corresponding fields INV 1 and INV 2 do not need to be populated. But currently they are required in HL7. It is proposed to make them conditional C(O/R), with the condition that MSH-9 1 equals to “INR” and MSH 9 2 equals to “U06”.
    • Due to the backward compatibility requirements defined in Chapter 2.8.2.c.4 " Existing required fields may be made conditional if a new trigger event has been applied. The condition must be specified such that the field remains required for the pre-existing trigger events." Since this is an existing trigger event, this change cannot be made.

  • Item 4:
    • Segment INV in INR^U06^INR_U06 shall be optional in order to enable queries without filtering on particular inventory item attributes
    • Due to the backward compatibility requirements defined in Chapter 2 existing required segments cannot be made optional.

The CR is changed: instead of redefining INR^U06^INR_U06, INR^U14^INR_U14 is introduced. --Dmytro (talk) 11:31, 17 March 2015 (EDT)
