IS_IPTR_TOTAL is a pre-defined user-defined field. This toggle enables clients to choose which time code sets to use for transaction totals in [IPTRB] and [IPTRE]. Only the time code sets they wish to use for transaction totals should have this toggle checked ON. If there are no time code sets with this toggle turned ON, the system will dynamically choose up to 15 time code sets to display in both [IPTRB] and [IPTRE].
