6.12.2   Difference Detection Tool when Saving a Rating Period

If work is under progress with several instances of the same Rating Period at the same time, the Difference Detection Tool appears when a save is made. That gives the possibility of comparing the differences between the two trees. This is especially useful if two persons, unwitting, are working with the same tree at the same time. For more information about the Difference Detection Tool, see Section 9.4.
