• Process designer and other functions.

• Business Explorer BEx is reporting and analysis tool that support query, analysis and reporting functions in. Using BEx, you can analyze historical and current data to different degree of analysis.

2)What is an InfoObject and why it is used in Unix ?

Ans:

• Info Objects are known as smallest unit in Unix and are used in Info Providers, DSOs, Multi providers, etc. Each Info Provider contains multiple Info Objects.

• InfoObjects are used in reports to analyze the data stored and to provide information to decision makers.

3) What are the different categories of Info Objects in  Unix system?

Ans:

Info Objects can be categorized into below categories −

• Characteristics like Customer, Product, etc.

• Units like Quantity sold, currency, etc.

• Key Figures like Total Revenue, Profit, etc.

• Time characteristics like Year, quarter, etc.

4) What is the use of Infoarea in Unix system?

Ans:

Info Area in Unix are used to group similar types of object together. Info Area are used to manage Info Cubes and Info Objects. Each Info Objects resides in an Info Area and you can define it a folder which is used to hold similar files together.

5) How do you access to source system data in BI without extraction?

Ans:

To access data in BI source system directly. You can directly access to source system data in BI without extraction using Virtual Providers. Virtual providers can be defined as InfoProviders where transactional data is not stored in the object. Virtual providers allow only read access on BI data.

6)What are different types on Virtual providers?

Ans:

• VirtualProviders based on DTP

• VirtualProviders with function modules

• VirtualProviders based on BAPIs

7) Which Virtual Providers are used in which scenario of data extraction?

VirtualProviders based on DTP −

Ans:

Ans: This type of Virtual Providers are based on the data source or an Info Provider and they take characteristics and key figures of source. Same extractors are used to select data in source system as you use to replicate data into BI system.

8) When to Virtual Providers based on DTP?

Ans:

• When only some amount of data is used.

• You need to access up to date data from a SAP source system.

• Only few users executes queries simultaneously on the database.

9) Virtual Provider with Function Module −

Ans:

This Virtual Provider is used to display data from non BI data source to BI without copying the data to BI structure. The data can be local or remote. This is used primarily for SEM application.

10) What is the use of Transformation and how the mapping is done in BW?

Ans:

Transformation process is used to perform data consolidation, cleansing and data integration. When data is loaded from one BI object to other BI object, transformation is applied on the data. Transformation is used to convert a field of source into the target object format.

Transformation rules −Transformation rules are used to map source fields and target fields. Different rule types can be used for transformation.

11). How do perform real time data acquisition in BW system?

Ans:

• Real time data acquisition is based on moving data to Business Warehouse in real time. Data is sent to delta queue or PSA table in real time.

• Real time data acquisition can be achieved in two scenarios −By using InfoPackage for real time data acquisition using Service API.

• Using Web Service to load data to Persistent Storage Area PSA and then by using real time DTP to move the data to DSO.

• Real time Data Acquisition Background Process −To process data to InfoPackage and data transfer process DTP at regular intervals, you can use a background process known as Daemon.

• Daemon process gets all the information from InfoPackage and DTP that which data is to be transferred and which PSA and Data sore objects to be loaded with data.

Ans:

To access data for reporting and analysis immediately after it is loaded,

14) What all data sources you have used to acquire data in Unix system?

Ans:

• SAP systems (SAP Applications/SAP ECC)

• Relational Database (Oracle, SQL Server, etc.)

• Flat File (Excel, Notepad)

• Multidimensional Source systems (Universe using UDI connector)

• Web Services that transfer data to BI by means of push

15) When you are using Unix.x, you can load the data to which component?

Ans:

In BW 3.5, you can load data in Persistence Staging Area and also in targets from source system but If you are using SAP BI 7.0 data load should be restricted to PSA only for latest versions.

16)What is an InfoPackage?

Ans:

• An InfoPackage is used to specify how and when to load data to BI system from different data sources. An InfoPackage contains all the information how data is loaded from source system to a data source or PSA. InfoPackage consists of condition for requesting data from a source system.

• Note that using an InfoPackage in BW 3.5, you can load data in Persistence Staging Area and also in targets from source system but If you are using SAP BI 7.0 data load should be restricted to PSA only for latest versions.

17) What is extended Star schema? Which of the tables are inside and outside cube in an extended star schema?

Ans:

In Extended Star schema, Fact tables are connected to Dimension tables and dimension table is connected to SID table and SID table is connected to master data tables. In Extended star schema you have Fact and Dimension tables are inside the cube however SID tables are outside cube. When you load the transactional data into Info cube, Dim Ids are generated based on SIDs and these Dim ids are used in fact tables.

18) How extended Star schema is different from Star schema?

Ans:

• In Extended Star schema one fact table can connect to 16 dimensions tables and each dimension table is assigned with 248 maximum SID tables. SID tables are also called Characteristics and each characteristic can have master data tables like ATTR, Text, etc.

• In Star Schema, Each Dimension is joined to one single Fact table. Each Dimension is represented by only one dimension and is not further normalized.

• Dimension Table contains set of attribute that are used to analyze the data.

19) which Data store object is used?

Ans:

DataStore object for direct update allows you to access data for reporting and analysis immediately after it is loaded. It is different from standard DSOs in the way how it processed the data. Data is stored in same format in which it was loaded to DataStore object for direct update by the application.

20) Explain the structure of direct update DSOs?

Ans:

One table for active data and no change log area exists. Data is retrieved from external systems using APIs.

• Below APIs exists −RSDRI_ODSO_INSERT: These are used to insert new data.

• RSDRI_ODSO_INSERT_RFC: Similar to RSDRI_ODSO_INSERT and can be called up remotely.

• RSDRI_ODSO_MODIFY: This is used to insert data having new keys.For data with keys already in the system, the data is changed.

• RSDRI_ODSO_MODIFY_RFC: Similar to RSDRI_ODSO_MODIFY and can be called up remotely.
• RSDRI_ODSO_UPDATE: This API is used to update existing data.
• RSDRI_ODSO_UPDATE_RFC: This is similar to RSDRI_ODSO_UPDATE and can be called up remotely.
• RSDRI_ODSO_DELETE_RFC: This API is used to delete the data.

21) Can we perform Delta uploads in direct update DSOs?

Ans:

As structure of this DSO contains one table for active data and no change log so this doesnt allow delta update to InfoProviders.

22) What is write optimized DSOs?

Ans:

In Write optimized DSO, data that is loaded is available immediately for the further processing.

23) Where do we use Write optimized DSOs?

Ans:

• Write optimized DSO provides a temporary storage area for large sets of data if you are executing complex transformations for this data before it is written to the DataStore object. The data can then be updated to further InfoProviders. You only have to create the complex transformations once for all data.

• Write-optimized DataStore objects are used as the EDW layer for saving data. Business rules are only applied when the data is updated to additional InfoProviders.

24) Explain the structure of Write optimized DSOs? How it is different from Standard DSOs?

Ans:

It only contains table of active data and there is no need to activate the data as required with standard DSO. This allows you to process the data more quickly.

25) To perform a Join on dataset, what type of InfoProviders should be used?

Ans:

Infosets are defined as special type of InfoProviders where data sources contains Join rule on DataStore objects, standard InfoCubes or InfoObject with master data characteristics. InfoSets are used to join data and that data is used in BI system.

26) What is a temporal join?

Ans:

Temporal Joins: are used to map a period of time. At the time of reporting, other InfoProviders handle time-dependent master data in such a way that the record that is valid for a pre-defined unique key date is used each time. You can define Temporal join that contains atleast one time-dependent characteristic or a pseudo time-dependent InfoProvider.

27) Where do we use InfoSet in BI system?

Ans:

• Infosets are used to analyze the data in multiple InfoProviders by combining master data charactertics, DataStore Objects, and InfoCubes.

• InfoCube −This is used for star schema, we can only append data, ideal for primary reporting.

• MultiProvider −It contains a physical data and allow to access data from different InfoProviders.

40) What do you understand by Start and update routine?

Ans:

• Start Routines − The start routine is run for each Data Package after the data has been written to the PSA and before the transfer rules have been executed. It allows complex computations for a key figure or a characteristic. It has no return value. Its purpose is to execute preliminary calculations and to store them in global Data Structures. This structure or table can be accessed in the other routines. The entire Data Package in the transfer structure format is used as a parameter for the routine.

• Update Routines −They are defined at the InfoObject level. It is like the Start Routine. It is independent of the DataSource. We can use this to define Global Data and Global Checks.

• When you are using x, you can load the data to which component?

• In BW 3.5, you can load data in Persistence Staging Area and also in targets from source system but If you are using SAP BI 7.0 data load should be restricted to PSA only for latest versions.

a) The key figures for a combination of characteristic SID values of the dimensions are stored in the fact table.

b) Changes to master data tables are only possible if new dimension keys are created in the fact table.

c) Both cumulative values and also key figures for non-cumulative values can be contained in the fact table. 

59) What is the dimension in BW? How would you optimize the dimensions?

Ans:

A dimension in BW is a collection of reference information about a measurable event in data warehousing. In this context, events are known as “facts”. For example, a customer dimension’s attributes could include first and last name, gender, birth date etc. To optimize the dimensions, do not add most dynamic characteristics into the same dimension and make the dimension smaller. Also, define as many dimensions as possible, and the dimension should not exceed 20% of the fact table size.

From meetings to project management programs and everything in between, there’s an endless list of tools and processes that project managers use to stay organized. Be sure to list as many tools as you can think of that you’re familiar with to demonstrate your knowledge of project management software and other tools.

Proactive Decision Making

• A project manager needs to be able to identify and prevent issues from impacting the project adversely. It is important that the candidate demonstrates the ability to take proactive steps, avoid procrastination, and not shy away from making tough decisions. Thus, candidates are often asked to share examples and real-life scenarios from their projects and life where they made proactive decisions. Here are a few such questions:

79) Give a few examples of proactive decision-making in your past projects and your life in general.

Ans:

It’s always important to take the initiative as a project manager, and your interviewer wants to see just how you do that. Think of specific project examples that included a lot of proactive decision-making, but don’t also be afraid to include examples that don’t include the workplace.

80) Can you give me a few examples of a time when you made a tough decision, and it backfired?

Ans:

This question is a tough one for candidates to handle as it tells the interviewer how honest you are with yourself and compels you to talk about an instance when you failed. Your interviewer wants to see how you handle setbacks because no matter how good you are at your job, they will happen. Most importantly, they want to know that you learned from these experiences. When you give your examples, explain how you used those setbacks to improve as a project manager overall.

81) What are some of the tools and resources you’ve used to develop your team?

Ans:

This is your chance to show your knowledge on some of the many different technologies that project managers use these days. Be sure to name any software programs, online tools, and other things that you’ve used to complete your daily tasks. Be sure also to explain that you are always open and eager to learn new tools or programs.

82) What is your delegation style?

Ans:

This is a question that is designed to ask about leadership skills. Explain what has been best for you and use examples of how your delegation style has worked well in the past. Even if you’ve never technically led a team before, it’s important to find an example of how you might’ve delegated in the past.

83) How easily do you delegate responsibility?

Ans:

Ans:Easily delegating responsibility is an essential quality of any project manager. Be sure to discuss a relevant example that assures the interviewer that delegating responsibility comes naturally to you.

84) How do you monitor and review the delegated responsibilities?

Ans:

As a project manager, it’s important to routinely stay on top of your team members’ tasks and responsibilities. Discuss how you do this with specific examples—whether it’s by scheduling brief meetings, using project management software, and so on.

• PMP Practice Exam Questions

• Challenge your project management skillsTAKE UP TEST

• Goal Focus

85). What are your career and project goals for the next six months?

Ans:

Be honest about any short-term project goals you have currently, as this shows the interviewer that you are enthusiastic about your projects and that you’re goal-oriented. When it comes to discussing your career goals, be sure to include the company you’re interviewing with as part of your goals. If you’re interviewing with a recruiter for job placement, you may not have a specific company in mind, and that’s okay—just be sure to be clear about what type of role you see yourself working in.

86)How do you control changes to your project?

Ans:

• Some level of change is inevitable, but as a project manager, it’s important to adapt to those changes quickly. Explain to your interviewer how you continue to keep your team on track whenever any project changes pop up.

Prioritizing and Time Management

• A project manager must tackle multiple tasks and issues. To be a successful project manager, you have to choose your battles wisely. Since resources are always limited, they need to be prioritized. Time is a valuable resource for the project because once lost; it cannot be recovered easily. As a result, Project time management is one of the key skills for any project manager. The following questions are asked to assess whether you are capable of taking up the responsibility for creating efficient ways to execute tasks:

87) How do you ensure that your project is always on track?

Ans:

Your interviewer wants to understand your work process and see that you’re detail-oriented. Explain how you check in with your team throughout a project. For example, you may want to point out that you believe effective and regular communication is key to ensuring that a project stays on track.
