51 51  N-n (pronounced 'N to N') mappings describe rules where a specified combination of values in multiple source Components map to specified values in one or more target Components. For example, when mapping a partial Series Key from a highly multidimensional cube (like Balance of Payments) to a single 'Indicator' Dimension in a target Data Structure.

133 133  The above behaviour can be okay if the series XMAN_Z_21 contains observations for different periods of time then the series XMAN_Z_34. If however both series contain observations for the same point in time, the output for this mapping will be two observations with the same series key, for the same period in time.
