IRE for non-cmdb classes in Robust transform map

[Amit D]

Hello, 

If you have IRE enabled for non-cmdb classes like core_company table and you have a robust transform map for it.

1. Will the robust transform automatically use IRE for company table instead of coalesce?

2. Do we need to enable IRE somewhere like we use CMDBTransformUtil in onBefore script in normal Transform map?

3. Has anyone tried IRE for non-cmdb tables without Integration hub ETL?

Thanks in advance.

BR,

Amit
