Mapplet input

Mapplet input

Mapplet input can be an Input transformation, a Source transformation, or both.
Use an Input transformation when you want the mapplet to receive input data from one or more upstream transformations. You can use multiple Input transformations in a mapplet. When you use the mapplet in a Mapplet transformation, each Input transformation becomes an input group. Use multiple Input transformations when you have multiple pipelines in a mapplet, or when you want the mapplet to receive input from multiple upstream transformations.
You include one or more Source transformations in a mapplet to provide source data. When you use only Source transformations for mapplet input, the mapplet is the first object in the mapping pipeline and contains no input groups.
A mapplet must contain at least one Input transformation or Source transformation.
For information about configuring Input and Source transformations, see
Transformations
