Input Table Mapping dialog
The operators that precede the Sub-Flow operator as inputs must map to the datasets that are the starting point for the sub flow. Use this dialog to map these elements.
The mapping is a one-to-one relationship between the inputs and the datasets in the sub flow. Corresponding tables should have the same columns as those used in the sub flow.
In the dropdown list, specify the sub-flow table dataset that maps to the input. See Sub-Flow for information.
