System-Defined Mapping Outputs
System-defined mapping outputs are mapping outputs that each mapping generates. You do not have to configure the aggregation for system-defined mapping outputs. You can pass system-defined mapping outputs to workflow variables.
A mapping returns the following types of system-defined mapping outputs:
- numberOfTargetRows
- The number of rows that the mapping wrote to the target.
- numberOfSourceRows
- The number of rows that the mapping read from the source.
- numberOfErrorRows
- The number of error rows that the mapping generated.
Configure the workflow variables to assign the system-defined mapping outputs to on the Output tab of the Mapping task Properties view.
The following image shows the system-defined mapping outputs on the Output tab:
