When shall we use “execute in SQL Engine”?

Observation: In one graphic calculation view, a script-based calculation view is used. If “execute in SQL engine” is not selected, the calculation results

  1. Are correct in HANA data preview
  2. Are correct in Lumira
  3. Are wrong in Analysis for Office
  4. Are wrong in Design Studio

Question: what is the best practice regarding “execute in SQL engine”? In which situation must this option be selected? In which situation must this option be kept empty?

    If the results differ with the SQL engine option selected, that most likely has to do with the semantic differences in how e.g. NULL are handled by the CE- respectively the SQL functions.

    Please check and in case this doesn't cut it

    • Nope, I don't have specifics of the mentioned clients.

      As a SAP employee you may want to open internal support messages in case of wrong result sets.

      Given your information, the SQL Engine flag and the wrong results coincide in 50% of the cases. That seems to be similar to rather chance and not correlation.

    The document attached to note 1857202 - SQL execution in Calculation Views should answer most of your questions.

      I read the notes but still don’t understand when to use SQL engine.

      In our case we have a CV that for some queries the SQL engine flag make better performance but for other SQL queries we get OOM (which we don’t get without this flag).

      I there any rule of thumb?

      We are in SP11.

    Hi all,

    I am also facing some issues and differences between HANA studio and Design Studio. When I am executing the view in HANA studio I am getting results for calculated columns, in Design Studio only 0 is shown. Can this be related to the same issue?

    I tried to have different settings with the SQL engine flag, but for me it didn't help.

    I will follow up with Ye on an internal ticket as well, but I hoped somebody faced the same issue and found a solution for that.

    Thanks a lot,
