Disabling incoming fields

Disabling incoming fields

You can disable incoming fields to connect only the generated sequence in the output fields, NEXTVAL and CURRVAL, to one or more downstream transformations. When you disable incoming fields, you cannot connect the Sequence Generator transformation to upstream transformations.
When you disable incoming fields, at least one field from another transformation must be connected to the downstream transformation along with the Sequence Generator fields. For example, if the mapping contains a Sequence Generator transformation and a Source transformation and the Sequence Generator transformation is connected to a Target transformation, you must connect at least one field from the Source transformation to the Target transformation.
The following image shows a mapping where incoming fields are disabled in the Sequence Generator transformation:
The mapping canvas shows the Source transformation and the Sequence Generator transformation connected to the Target transformation.
You cannot disable incoming fields in an
elastic mapping
