When you use a mapplet in a Mapplet transformation, Data Integration renames the transformations in the mapplet at run time.
When you use a mapplet in a Mapplet transformation, the mapplet might contain transformations with names that conflict with other transformation names in the mapping. To avoid name conflicts, Data Integration prefixes the names of the transformations in the mapplet with the Mapplet transformation name.
For example, a mapplet contains an Expression transformation named Expression_1. You create a mapping and use the mapplet in the Mapplet transformation Mapplet_Tx_1. When you run the mapping, the Expression transformation is renamed to Mapplet_Tx_1_Expression_1.
If a mapplet contains another Mapplet transformation, Data Integration also prefixes the transformation names with the second Mapplet transformation name. For example, the mapplet in the previous example also contains a Mapplet transformation named MappletTx, which contains FilterTx_1. In the mapping, FilterTx_1 is renamed to Mapplet_Tx_1_MappletTx_FilterTx_1.
Data Integration truncates transformation names that contain more than 80 characters.
Note: Data Integration only renames transformations in mapplets when the mapplet is used in a mapping created after the April 2022 release.
