Configuring the tMemorizeRows component

Procedure

Double-click the tMemorizeRows component to open its Basic settings view on the Component tab.
In the Row count to memorize field, type in the maximum number of rows to be memorized at any given time. As in this example you need to compare ages of two customers for each time, enter 2. This component memorizes two rows at maximum at any given moment and always indexes the new incoming row as 0 and the previous incoming row as 1.
In the Memorize column of the Columns to memorize table, select the check box(es) to determine the column(s) to be memorized. In this example, select the check box corresponding to age.
