Notes
-
For logics in the "Collect" category (hereinafter: Collective logic), result data that meet the following conditions are output:
-
The input source of the first input handler is below the loop point.
-
The output target of the Collective logic is above the loop point.
Therefore, the result data of the Collective logic can't be output if the output schema is of table model type because the output target can't be set above the loop point.
= Hint =In case of outputting the aggregation result to a table model type component, first aggregate data using XML type output schema, and then output the result to the table model type component using Mapper.
-
-
The value of single input node will be output if output schema is not set to loop mapping.
