System-Defined Mapping Outputs

System-Defined Mapping Outputs

A mapping or transformation can return system-defined outputs. You can use the mapping output in a subsequent run of the workflow or by the next task in the workflow.
You can persist the mapping output in the repository or bind the mapping output to a workflow variable. You can use the mapping output in a subsequent run of the workflow or pass the value to another task in a workflow, such as a Notification task or an Exclusive Gateway task.
For instance, a transformation can return a system-defined output, numberOfErrorRows, that contains the number of records that were invalid. You might review this information to monitor a process or to understand the quality of the data that a mapping processes.
The following table describes the output data produced by the Exception transformation in the mapping:
Transformation
Output Data
Datatype
Description
Exception
exceptionLoadCount
Integer
Number of records that contain unresolved data quality issues and require a manual review. The records may contain errors, or they may contain duplicate information.
The Developer tool lists a single instance of the exceptionLoadCount output even if the mapping contains multiple Exception transformations. Assign the exceptionLoadCount output to a workflow variable if the mapping contains a single Exception transformation. Otherwise, unexpected behavior may occur.
