Definition: Use if this RXG segment carries information about a single administration. Starts with 1 for the first scheduled give date/time transmitted by the pharmacy/treatment supplier for this order. Increments by one with each additional scheduled give date/time for this order.
If the RXG segment carries information about multiple administrations, this field's value is zero (0), since in this case a one-to-one matching with the RXA segment is ambiguous.
