• Question 34:

  Which features does SAP Analysis for Microsoft Office provide? Note: There are 3 correct answers to this question.

  A. Changing context menu entries

  B. Dragging measures in and out of the report

  C. Displaying data simultaneously in a table and a chart

  D. Including more than one data source

  E. Creating bookmarks for a navigation state

  Correct Answer: BCD

• Question 35:

  How can the delta merge process be initiated in SAP BW/4HANA? Note: There are 2 correct answers to this question.

  A. By setting a specific flag in the data transfer process

  B. By using a specific process type in a process chain

  C. By setting a specific flag in the transformation

  D. By using the SAP BW/4HANA data load monitor.

  Correct Answer: B

  The delta merge process is used to transfer data modifications from the delta storage to the main storage in SAP HANA database. It can be initiated in SAP BW/4HANA in the following ways:

  1.

  By using a specific process type in a process chain, called Trigger for DB Merge. This process type can be added to a process chain and linked to the loading processes that require a delta merge. The process type allows specifying the object type and name for the delta merge.

  2.

  By using the SAP BW/4HANA data load monitor, which is a web-based tool for monitoring and managing data loads. The data load monitor has an option to trigger a database merge for an object after a successful data load.

• Question 36:

  What is the request handling default setting for error handling in a data transfer process (DTP) in SAP BW/4HANA?

  A. Request is set to failed, error stack is written, and valid records are updated

  B. Request is canceled, records are not tracked, and tarjet is not updated

  C. Request is set to success, error stack is written, and valid records are updated

  D. Request is canceled, firt incorrect record is tracked, and target is not updated.

  Correct Answer: B

• Question 37:

  Which recommendations should you follow to optimize BW query performance? Note: There are 3 correct answers to this question

  A. Use fewer drill-down characteristics in the initial view

  B. Use characteristic filters that overlap

  C. Use exclude functions in the restricted key figures

  D. Use mandatory characteristic value variables

  E. Use include functions in the restricted key figures.

  Correct Answer: ADE

  Use fewer drill-down characteristics in the initial view: This can improve the query performance by reducing the amount of data that needs to be transferred and displayed at the start of the query execution. The user can drill down to more

  details later if needed.

  Use mandatory characteristic value variables: This can improve the query performance by restricting the data selection to a smaller set of values that are relevant for the user. The user can also change the variable values later if needed.

  Use include functions in the restricted key figures: This can improve the query performance by avoiding unnecessary calculations and aggregations that are done when using exclude functions. Include functions are also more efficient than

  selections or restricted key figures when filtering data.

• Question 39:

  What does a Composite Provider allow you to do in SAP BW/4HANA? Note: There are 3 correct Answers to this question.

  A. Combine Infoprovider using Join and Unions

  B. Join two ABAP CDS views

  C. Define new restricted key figures

  D. Create new calculated fields Integrate

  E. SAP HANA HDI calculation views.

  Correct Answer: ACE

  Combine InfoProviders using Join and Unions: This is what a Composite Provider allows you to do in SAP BW/4HANA. A Composite Provider is an InfoProvider that combines data from several analytic indexes or from other InfoProviders (by union or inner join or left outer join), and makes this data available for reporting and analysis. Storing the data in BW Accelerator or in an SAP HANA database also ensures faster access to data in the query.

  Define new restricted key figures: This is what a Composite Provider allows you to do in SAP BW/4HANA. A Composite Provider can define new restricted key figures based on the existing key figures of the underlying InfoProviders. Restricted key figures are key figures that are restricted by one or more characteristics.

  Integrate SAP HANA HDI calculation views: This is what a Composite Provider allows you to do in SAP BW/4HANA. A Composite Provider can integrate SAP HANA HDI calculation views as part of its data sources, using a virtual table or an external SAP HANA view. This can enable mixed modeling scenarios that leverage both SAP BW/4HANA and SAP HANA capabilities.
