Identify the statement(s) that is/are true. A change run...
a. Activates the new Master data and Hierarchy data
b. Aggregates are realigned and recalculated
c. Always reads data from the InfoCube to realign aggregates
d. Aggregates are not affected by change run
ANSWER(S): A, B
Change run activates the Master data and Hierarchy data changes. Before the activation of these changes, all the aggregates that are affected by these changes are realigned. Realignment is not necessarily done by reading InfoCubes. If these are part of another aggregate that can be used to read data for the realignment, change run uses that aggregate.
