- Using a auto-correct load option in a target table.
- Including Table Comparison transform in a data flow.
- Designing a data flow to completely replace a target table during each execution.
- Including a preload SQL statement to execute before table loads.
76. What Is Use Of Auto Correct Load?
It does not allow duplicated a data entering into a target table.It works like Type 1 Insert else Update a rows based on Non-matching and matching data respectively.
77. What Is Use Of a Array Fetch Size?
Array fetch size indicates a number of rows retrieved in the single request to a source database. The default value is be 1000. Higher numbers reduce requests, lowering network traffic, and possibly improve the performance. The maximum value is be 5000
78. What Are Differences Between the Row-by-row Select And Cached Comparison Table And Sorted Input In a Table Comparison Transform?
- Row-by-row select – look up a target table using a SQL every time it receives an input row. This option is best if a target table is large.
- Comparison table that has been cached — To save the comparison table in memory. When comparing the whole target table and a table fits in memory, this approach works well.
- Sorted input — To read a comparison table in order of the primary key column(s) using sequential read.This option improves the performance because Data Integrator reads a comparison table only once.Add a query between a source and the Table_Comparison transform. Then, from a query’s input schema, drag primary key columns into Order By box of the query.
79. What Is Use Of Using Number Of Loaders In a Target Table?
Number of loaders loading with the one loader is known as Single loader Loading. Loading when a number of loaders is greater than one is known as a Parallel Loading. The default number of a loaders is 1. The maximum number of a loaders is 5.
80. What Is Use Of a Rows Per Commit?
Specifies a transaction size in number of rows. If set to a 1000, Data Integrator sends a commit to underlying database every 1000 rows.
81. What Is Difference Between a Lookup (), Lookup_ext () And Lookup_seq ()?
lookup() : Briefly, It returns a single value based on a single condition.
lookup_ext(): It returns a multiple values based on a single/multiple condition(s).
lookup_seq(): It returns a multiple values based on a sequence number.
82. What Is Use Of a History Preserving Transform?
The History Preserving transform allows to produce new row in a target rather than updating an existing row. And can indicate in which columns are transform identifies changes to be preserved. If a value of certain the columns change, this transform creates new row for a each row flagged as a UPDATE in a input data set.
83. What Is Use Of a Map-operation Transform?
The Map-Operation transform allows to change the operation codes on data sets to produce a desired output. Operation codes: INSERT, UPDATE, DELETE, NORMAL or DISCARD.
84. What Is a Heirarchy Flatenning?
Constructs the complete hierarchy from a parent/child relationships, and then produces the description of a hierarchy in vertically or a horizontally flattened format.
- Parent Column, Child Column.
- Parent Attributes, Child Attributes.
85. What Is Use Of a Case Transform?
Use of a Case transform is to a simplify branch logic in the data flows by consolidating case or decision-making logic into a one transform. The transform allows to split a data set into the smaller sets based on a logical branches.
86. What are bunch of a tools available under business objects 4.0 platform?
A Business User tools : Business user tools are ones intended for the business user (example –HR manager or financial manager of any organization) which help them to view and manage the business reports to aid them in decision-making process.
Data manager tools : They are used to design the sematic layer between designer tool and its source of a data.
Designer tools : It provides a facility to design a query based on a reporting requirement.
87. What is a bi launch pad?
BI launch pad is the SAP BO BI 4.0 business user tool used for a broadcasting the reports. It provides interface to a SAP BO business intelligence platform repository that enables us to navigate to view & manage the business intelligence documents. It is the web based application/portal from where can access reports and organize a reports as per our need.
88. What is result of a query?
The result of query is a final report. A report is the business representation of a data.
89. Define a drill mod?
This is a kind of a analysis mode associated with the business objects and helps in breaking down data as well as viewing data from all the possible angles and levels of detail for a discovering the factor that has a caused good – bad result.
90. If business needs highly formatted reports, which tool would choose?
Would go with a ‘SAP crystal reports for an enterprise’ in this case as it gives more powerful formatting options.
91. What is personal connection?
Personal connection can be created only by the single user and it can’t be made used by a others. The details regarding such connection can be usually stored inside a PDAC.LSI file.
92. What are he different type of a connections available?
- Personal connection
- Shared connection
- Secured connection
93. What is a shared connection?
This is kind of connection that is usually made used by the other user via a server which is shared one. The details regarding a connection can be stored within a SDAC>LSI file which can be found within an installation folder of a business objects.
94. Which of connection did use in a project and why?
- In project, were using a secured connection as were working in a team and also reports had to be shared between a cross-functional team.
- Had to create a BO reports over the IDT universe and publish these reports. When it comes to the live project, the secured connection is the best kind of connection to use a because here we can limit the access to various users. Also, secured connection can be accessed from a different servers.
- The last and main reason of the using secured connection is that since it is saved in a repository, so if requirement is to publish the reports over repository, and will have to use a secured connection.
95. What is secured connection?
Secured connection is a kind of connection that can be helpful in a overcoming the various limitations associated with a former connections. The rights related with this kind of a connection can be set over documents as well as the objects. Universes can be brought inside central repository only by making use of a secured connection. The parameters regarding these connection care usually saved inside a CMS.
96. Explain idea of a universe in bo and its relevance with assignments have worked upon?
- A universe is the logical layer between backend and a front end of reporting. It is a metadata layer which isolates as technical complexities of the source system from a business user/report developer.
- In a universe, the required attributes and measures are picked up from a backend and arranged in a way want to use them further for reporting. In my project, and used to create IDT universe on top of the calculation views developed in HANA. These IDT universes were further utilized to create a BO reports.
97. Define a custom hierarchies?
The custom hierarchies can be used for explaining the universe for facilitating drill down that is customised and can happen between the objects from various or same classes considering a user requirements.
98. Define a context in a universe?
Context can beexplained as a particular path of join between a specific group of joins or tables for purpose of a particular query. A particular object that can be found inside a column of a table, belonging to a particular context is supposed to be compatible to all various kinds of objects belonging to same context. In the case of objects that are from various kinds of context, different kinds of a SQL can be generated, and the results can be merged inside a micro cube. This is for making sure that there is no incorrect result associated with the loop or any other kind of issue related with a join path.
99. How universes created in idt are made available in a bo?
Once universe is be created, and publish the universe using a secured connection and then import a universe in BO to make a report on top of it.
100. Define chasm trap?
Chasm trap is the condition that arises when the values inside a fact table get inflated at the time of measuring values from two different fact tables by considering a dimensions inside dimension table.
