HANA live view

[Former Member]

Hi Experts,

Any answer why SAP HANA live is build completely on Calculation views ( even for master data ). Does it recommends us to use CV in our modeling as well.

Thanks & Regards,

For extending HANA Live views there is SAP HANA Live Extension Assistant - SAP HANA Live for SAP Business Suite Administrator's Guide - SAP... - please use this.

If you are building your own, you should use A/B testing to see works best in your scenario. SAP did so much optimization for HANA Live that really it doesn't matter if you use Attribute Views, Analytic Views, Calculation Views. If your model is syntactically sane then they will all perform the same in SPS09.

Only when you have very large data volumes (>1-10bn rows) do you need to be careful.

Thanks John for your response.

Could you please elaborate more in detail of this sentence.

If your model is syntactically sane then they will all perform the same in SPS09.

Is there something big change how the views work in back end in SPS09?

No, the changes happened in SPS07 and SPS08. They did a lot of optimizations of calc views because of HANA Live. As a result, if you build a model different ways, you should find they all perform the same.

Hi Siva,

I think the SAP HANA Live views were created only in Calculation views to make it more simple.

In terms of what you should be doing. I would recommend reading a bit more about modeling and then determining what view is best in what situation.
