This step acts as a mapping step to map from a set of input fields to CDM fields. The step is accessed in the Design window by choosing Transform->Map to CDM.

This step can be configured to map from any input fields, but can only map to CDM fields. In the step properties there are three tabs: Select & Alter, Remove and Meta-data.

The Select & Alter tab allows for fields to be selected for inclusion, and renamed. The Get fields to select button on the right-hand-side of the window can be used to automatically determine the available fields from previous steps.

The Remove tab is used to remove fields from the stream. This is useful to prevent unwanted fields from an input source being mapped to CDM (for example if there is no appropriate field to map to), or to remove temporary calculation fields from earlier steps.

The Meta-data tab allows definition of the mappings from the input fields to the CDM Fields. Select an input field in the Fieldname column, and choose a CDM field to map to from the dropdown in the CDM Field column.
