The non-native environment uses distributed processing and processes data on different nodes. Each node does not have access to the data that is being processed on other nodes. As a result, the runtime engine might not be able to determine the order in which the data originated. So, when you run a mapping in a non-native environment and you run the same mapping in the native environment, both mappings return correct results, but the results might not be identical.

Each of the run-time engines in the non-native environment can process mapping logic differently. In the non-native environment, Informatica transformations might be fully supported, supported with restrictions, or not supported. Similarly, in the native environment, some Informatica transformations and transformation behavior might not be supported.
