Same options with little tricky combinations

8. Few Q:s on ETL / Transformation..Ans: is Data Services.

9. Newest Connection method for Data Services ( TZHANA – 67)Ans: ODP (4.0)

10. What can you use to import data from SAP Business Warehouse into SAP HANA.

11. Extractors, ODP(Operational data provider ) which of the following tools can you use for

complex transformation

12. What is difference between Data Services and SLT and which does SAP recommend?

(Answer: DS is near real time, SLT is real time. SAP recommends SLT even if real time isn’t a

consideration)

13. Which technologies use the trigger-based approach? ( SLO, SAP LT, TDMS, Near zero downtime )

14. Why you use Data services for? ( load large volume of data , load data, transformation)

15. How do you import BW data to HANA, What connection do you use?

Options( data services, something like SSLE) data services via abap data flows.

16. You have to use ABAP data flows to transform large amounts of data into HANA from DS (this is

a question on the exam)

TZHANA- 67 ABAP data flows

17. SLT questions – When do you use it, how to make connections to HANA( DB) source is RFC,

there are also a few questions on Trigger Based replication in general (Page number 92 of

tzhana)

18. SD11 is the ERP transaction you have to use to see dependencies for tables you want to replicate

in HANA

19. You want to use a small look-up tables in your model for data ( i put ROW for this one) - This is

an actual question.

TZHANA: page number67. Read table via data flows

Page 7: HANA Associate

20. Which technology uses trigger based applications?

21. What can you use to import data from SAP Business Warehouse into SAP HANA?

Tzhana page 68: ODP (operational data provider) data replication API (extractors),custom

extractors through RS02.

27. Order of steps for BW?

28. Which one is related to SLO Technology?(I picked NearZero downtime,TDMS, SAP LT)

29. How DB trigger works?

Answers: Only relevant tables considered for DB recording, all relevant changes are recorded in

logging tables.

30. On controller module:

A. Ensures mapping between HANA DB structure and DB structure of source system.

B. Provides ability to conversion/migration values (date fields into strings)

C. Includes features to manage entire replication process in a holistic manner, e.g. provides

scheduling options to determine the frequency of data replication.

E. Triggers activities of WRITE module

Answers: ensures mapping between SAP HANA DB struc and source system.

31. From some options which one is used for single sign on (I remembered only one name excel)?

Near realtime

Profilt analysis with plan vs actual

2. Which application of hana will you choose?

Two confusing answers

1) COPA extractors.

2) Smart analytics

3) Some hana oil and gas application.

3. In the above either we have to choose copa or smart I choose smart? Copa is correct for near

realtime but it is not application it is the extractor.

4. Where will you create a custom attribute in analytic view

1) Calculation attribure

2) Calcualation measure

3) Restricted

4) Private

I choose calculation attribute ? know the difference between calculation att and

measure.\

5. How will you get the more than 5000 records

1) configure the array fetch of records.

2) configure the business layer

I eliminated the other two which is not valid but could not choose the right one between these

two finally I choose the array.

6. you have to have restrict a column? How will you do it? Control on business layer? Confusing

statements

7. In the prerequisites calculation view of the graphical type( confusing question) which options

you select

1) define foundation

2) define output

3) define projection

4) save and activate?

I choose first 3…..

Page 10: HANA Associate

May be with out projection we can do????????????

8. To activate a view on which schema you need rights.

SYS_BI / SYS_BIC/SYS_REPO/?

Ans: Sys_BIC

Note: SYS_REPO is needed to read from activated views…But the Q: is “to activate view” that’s the

tricky part. ☺

9. A View is activated or imported not sure …But Q is how will you activate dependent views..

Options “Activate one by one manually” / Cascade activation / ? / ?

I choose cascade activation??? Other answer close to this is active one by one manually….

Confused????

10. A view has been derived from another view? What can be changed?

Description / filters / description mapping / joins?

I choose description change.

Filters can be changed, description can be changed, joins,

NOTE: Derived view is “Read-Only” and Copied is ..Slide 121 TZHANA.

11. How do you check the calculation speed of the query ?

Choices Performance monitor in studio / ? / ? / ?

12. UNIOIN,JOIN,PROJECTION

Needed for calculation view graphics

13. Which inputs of models you select for the analytic view

1) Calc view (wrong ans)

2) Analytic view

3) Tables

4) Attribute view

I choose analytic and attribute( these are the models) one you choose attribute for sure

other one you have to between analytic and tables

14. Which_ inputs object you select?

1) Attribute view

2) Analytic view

3) Columnar tables

Page 11: HANA Associate

4) Calculation view

I choose columnar tables ( this is the object)

15. TZHANA Slide 176 – when to use Calculation View

Ans:: Key figures span across tables.

16. Attribute view with Key and non-keys… with hierarchies.

17. Lesson 8 PDF file “CO-PA for HANA” => Slide 16. Ans: ROOSOURCE.

18. A view is been changed, how do you check what are the other dependent views affected.

Options “ Where-Used-list “/ something related to documentation./?/?

19. A View is activated or imported not sure …But Q is how will you activate dependent views..

Options “Activate one by one manually” / Cascade activation / ? / ?

Venkat ans: MASS ACTIVATION USING THE QUICK LAUNCH.

20. What are the direct outputs of Analytic View?

Choices: Private Attribute / Key Attribute / Attribute View / Restricted Attribute / Calculated

Measure / Measure / Calculated Attribute / Restricted Measure

Private attributes, Measures, Calcualted measures, restricted measures.

<N ote: How to check these …for ex: understand the screen shot of Slide 144 check the nodes of

“Output” secton. Also check the RHANA – Demo for each chapter. Where the tutor walks thru

step-by-step creating all three different type of views. Pay more attention to what he clicks as

well as other options surrounding in the same screens.>

Note: Choices were only 4-5 but the same were repeating with different combinations for other

Q:s like “Direct output for Attribute View” and “also check for Calculated View”…Best is

understand the importance of each attribute and which will be the output for each view.

Also understand what are the inputs for the same above views?

21. Text mapping / description mapping? what type of join can it be compared with or what’s the

next closest match something close …..? Tricky Q: but should be easy to analyze if you know the

result of other joins.

Choices any one: inner join/left outer join /right outer join / referential join.

Note: choice did not have “Text join” ☺ . you need to choose the next best match from the

above.

Page 12: HANA Associate

BEST ANSWER IS LEFT OUTER JOIN.

22. What’s the pre-requisite or mandatory of analytic view? Tricky Q:.

Note: we generally think that it needs to have “1 attribute and 1 measure”.

But the choices are: One data foundation with more attribute view / One attribute view with

more data foundations /

Page 13: HANA Associate

23. What’s the pre-requisite or mandatory of analytic view? Tricky Q:.

Note: we generally think that it needs to have “1 attribute and 1 measure”.

But the choices are: One data foundation with more attribute view / One attribute view with

more data foundations /

24. Pre-requisite for data foundation is 1 attribute and 1 measure.
