Hi Gurus,
We are in the process of building the SAP HANA views. As we know there are multiple options
1) Attribute , Analytic & Calc views
2) Scripted Calculation views and CE functions.
I have read many articles and as per SAP Documentation, they say build the information view with Attribute, analytic and calculation View (Graphical) If it does not suffice they go for scripted calculation view.
Just wanted to understand. Are there any limitations or any issues faced in the projects with scripted calc views. If we look at the John Appleby tips, it suggests that avoid SQL script unless it cannot be done with graphical views.
If we build the views with graphical method, then it seems the parallelism can very well achieved ,means query is split into multiple sub queries and executed in parallel as in Visualize plan.
If we write the Sql script, can this parallel processing achieved or not ? If the requirement can be achieved without writing script which method to choose.
I have included the 10 to 12 attribute views in analytic view then Calculation view; it seems there may be some performance issue which I am going to check. As we know we can use base table directly in calculation view. What is the best method to use .Can we use these base tables in calculation view directly or build the attribute views first, then analytic view and after that build calculation view.
As we know we use the attribute views from re usability perspective. Is there any other reason that we need to use attribute views instead of joining the base tables in calc view .
