SAP BW/BI Interview Questions and Answers - 2

11.What use marker in MM? Marker update is just like check point. ie it will give the snapshot of the stock on a particular date ie when was the marker updated. Because we are using Noncumulative keyfigure it will lot of time to calculate the current stock for example at report time. to overcome this we use marker update Marker updates do not summarize the data.. In inventory management scenarios, we have to calculate opening stock and closing stock on a daily basis. In order to facilitate this, we set a marker which will add and subtract the values for each record. In the absence of marker update, the data will be added up and will not provide the correct values.
 12.Tell me web template? You get information on where the web template details are stored from the following tables : RSZWOBJ Storage of the Web Objects RSZWOBJTXT Texts for Templates/Items/ Views RSZWOBJXREF Structure of the BW Objects in a Template RSZWTEMPLATE Header Table for BW HTML Templates You can check these tables and search for your web template entry . However, If I understand your question correctly , you will have to open the template in the WAD and then make the corrections in the same to correct it.
 13.What is dashboard? A dash board can be created using the web application Designer (WAD) or the visual composer (VC). A dashboard is just a collection of reports, views and links etc in a single view. For e.g. igoogle is a dashboard. A dashboard is a graphical reporting interface, which displays KPIs (Key Performance Indicators) as charts and graphs. A dashboard is a performance management system When we look at the all organization measures how they are performing with helicopter view, we need a report that teaches and shows the trend in a graphical display quickly. These reports are called as Dashboard Reports, still we can report these measures individually, but by keeping all measures in a single page, we are creating single access point to the users to view all information available to them. Absolutely this will save lot of precious time, gives clarity on decision that needs to be taken, helps the users to understand the measure(s) trend with business flow creating dashboard Dashboards : Could be built with Visual Composer & WAD create your dashboard in BW, (1) Create all BEx Queries with required variants,tune them perfectly. (2) Differentiate table queries and graph queries. (3) Choose the graph type required that meet your requirement. (4) Draw the layout how the Dashboard page looks like. (5) Create a web template that has navigational block / selection information. (6) Keep navigational block fields are common across the measures. (7) Include the relevant web items into web template.
(8) Deploy the URL/Iview to users through portal/intranet The steps to be followed in the creation of Dashboard using WAD are summarized as below: 1) Open a New Web template in WAD. 2) Define the tabular layout as per the requirements so as to embed the necessary web items. 3) Place the appropriate web items in the appropriate tabular grids 4) Assign queries to the web items (A Query assigned to a web item is called as a data provider) 5) Care should be taken to ensure that the navigation block.s selection parameters are common across all the BEx queries of the affected dataproviders. 6) Properties of the individual web items are to be set as per the requirements. They can be modified in Properties window or in the HTML code. 7) The URL when this web template is executed should be used in the portal/intranet 

14.How can you solve the data mismatch tickets between r/3 and bw? Check the mapping at BW side for 0STREET in transfer rules.Check the data in PSA for the same field.If the PSA is also doesn't have complete data then check the field in RSA3 in source system. 
16)What is replacement path tell me one scenario? 

17.What is difference between PSA & IDOC? BI7 is PSA used only for Data load from Source System into BW 
18). what we do in Business Blue Print Stage? SAP has defined a business blueprint phase to help extract pertinent information about your company that is necessary for implementation. These blueprints are in the form of questionnaires that are designed to probe for information that uncovers how your company does business. As such, they also serve to document the implementation. Each business blueprint document essentially outlines your future business processes and business requirements. The kinds of questions asked are germane to the particular business function, as seen inthe following sample questions:1) What information do you capture on a purchase order?2) What information is required to complete a purchase order?Accelerated SAP question and answer database:The question and answer database (QADB) is a simple although aging tool designed to facilitate the creation and maintenance of your business blueprint.This database stores the questions and the answers and serves as the heart of your blue print. Customers are provided with a customer input template for each application that collects the data. The question and answer format is standard across applications to facilitate easier use by the project team.Issues database: Another tool used in the blueprinting phase is the issues database. Thisdatabase stores any open concerns and pending issues that relate to the implementation. Centrally storing this information assists in gathering and then managing issues to resolution, so that important matters do not fall through the cracks. You can then track the issues in database, assign them to teammembers, and update the database accordingly. 
19). How do we gather the requirements for an Implementation Project? One of the biggest and most important challenges in any implementation is gathering and understanding the end user and process team functional requirements. These functional requirements represent the scope of analysis needs and expectations (both now and in the future) of the end user. These typically involve all of the following:- Business reasons for the project and business questions answered by the implementation- Critical success factors for the implementation- Source systems that are involved and the scope of information needed from each- Intended audience and stakeholders and their analysis needs- Any major transformation that is needed in order to provide the information- Security requirements to prevent unauthorized useThis process involves one seemingly simple task: Find out exactly what theend users' analysis requirements are, both now and in the future, and buildthe BW system to these requirements. Although simple in concept, in practicegathering and reaching
a clear understanding and agreement on a complete setof BW functional requirements is not always so simple. 

20) How do we decide what cubes has to be created? Its depends on your project requirement. Customized cubes are not mandatory for all the projects. If your bussines requirement is differs from given scenario ( BI content cubes ) then only we will opt for customized cubes.Normally your BW customization or creation of new info providers all are depending on your source system.If your source system other that R3 then you should go with customization of your all objects.If your source system is R3 and your users are using only R3 standard business scenarios like SD,MM or FI... etc., then you dont want to create any info providers or you dont want to enhance any thing in the existing BW Business Content. But 99% this is not possible. Because surely they should have included their new business scenario or new enhancements.For example, In my first project we implemented for Solution Manager BW implemention. There we have activated all the business content in CRM. But the source system have new scenarios for message escalation, ageing calculation etc., According their business scenrio we could't use standard business content. For that we have taken only existing info objects and created new info objects which are not there in the business content. After that we have created custom data source to info providers as well asreports.
