    Hi,

    when using a scripted view, there are SQL-Statements that are not supported by the calculation engine. In this case Hana switches to the row engine to calculate the result. This has impact on the performance. Calculation view normaly executed in the calculation engine.

    Best Regards

    Hi Thorsten,

    Thanks for the response.

    I think Row Engine comes in the scenario when there are row based table involved. But here you have mentioned that in scripted view executed in Row Engine as Calc Engine is not supported.

    So my question is that, whether Scripted calc view is executed via Row Engine every time ?
