Thanks Suhas,
When using "Read from DataStore" to get the required fields from other DSOs.
In this case, transformation from DSO2 -> DSO3, DSO1-> DSO3 by using Read from DataStore,
Is the primary the primary key of DSO1 already indexed?
For the complex transformation eg the max or min of DSO1 , is it using routine and writing ABAP?
Your help is much appreicated.
Best Regards,
Keith
