Top 50 Sap Bw Interview Questions You Must Prepare 02.Mar.2024

These are variables used in calculations in the query; for example take a customer discount report where each customer is given a different percentage discount; you create a formula variable for the discount percentage and use it in the calculated key figure.

You can create a start condition (transaction: SWB_COND) and set it to start if the notification type is M@Just make sure to document this because months from now you might not remember why it starts selectively for some and not others. For the second question - if you are trying to notify the agent that they have a task, then try placing this standard task into a custom 2 step workflow template. The first step of the template should send an express mail then the next step should automatically send the task.

• ODS: Provides granular data, allows overwrite and data is in transparent tables, ideal for drilldown and RRI.
• CUBE: Follows the star schema, we can only append data, ideal for primary reporting.
• MultiProvider: Does not have physical data. It allows to access data from different InfoProviders (Cube, ODS, InfoObject). It is also preferred for reporting.

Use the AWB -> Reporting agent and select the value set icon on the left.

Performance. Sending 1 mail to 20 recipients will cost considerably less performance than sending 20 individual mails. If the mail is sent as a SAP Office mail (as opposed to e-mail, fax...) disk space will also be a factor because the SAP office mail will only exist once in the database, with references being created for each of the recipients.

The only time you need to cons ider individual mails with a dynamic loop is when the text of the mail varies from one recipient to another.

Time dimensions are automatically converted; for example if the cube contains calendar month and your transfer structure contains date, the date to calendar month is converted automatically.

Exception is not a filter (like condition) but used to highlight reports with different colors for unusual key figures; for example you may want to show red for all accounts receivables that are older than 90 days and yellow for older than 60 days.

This is a group of events which complete independently of one another; use this to check the successful status of multiple events; for example you can trigger a chain event if all loads are successful.

The transformation rules for data from source system to info source/communication structure.

a. Number of records. 
b. Summarization ration (compression) .
c. Last used date — remember if you don’t see any recent activity then this aggregate is not used.

Defines number of parallel processors in activation, mm number of data records and wait time.

A fact table at the center and surrounded (linked) by dimension tables.

a. access via OLAP engine.
b. infosets can join flat BW objects like master data attributes, etc.

These are defined as levels where information is maintained; example customer groups, divisions, etc.

This is to avoid inconsistency and make sure that only verified data is entered into the system.

From a query name or description, you would not be able to judge whether the query is having any exception.There are two ways of finding exception against a query:@Execute queries one by one, the one which is having background colour as exception reporting are with exceptions.@Open queries in the BEX Query Designer. If you are finding exception tab at the right side of filter and rows/column tab, the query is having exception.

By default the report shows overall results total and not the results total only for the filtered results; to display the right totals you should use “Summation” in the key figure properties instead of “Nothing defined”.

Yes, When you want to report on characterstics or master data, you can make them as info provider. Ex: you can make 0CUSTMER as info provider and do Bex reporting on 0 CUSTOMER;right click on the info area and select Insert characterstic as data target.

a. define the properties
b. create class types; this controls the classes assigned to them; for example class type can be material
c. create classes and assign to a class type; for example class could be digital cameras
d. assign objects
e. now searches can be done on classes; for example get all the cameras with 3.0 mega pixels.
f. These values are transferred to BW as Omaterial attributes

There are two fact tables for each info cube; it is the E table and the F table;

Operations data Source you can overwrite the existing data in ODS.

These kinds of key figures are not summarized (unlike sales, etc); examples are head count, inventory amount; these are always in relation to a point in time; for example we will ask how many employees we had as of last quarter. We don’t add up the head count.

This defines the maximum size of packet, max no of records per packet, the number of parallel processes, etc.

a. Master data.
b. Transaction data.
c. Hierarchies. 
d. Database .
e. Aggregation.

These are non cumulative changes used to get the right quantity.

4(3 Sap defined and 1 customer defined).

HRPTDWO1 - for HR time related data.

a. first verify that the DB connection works from the server
b. AWB -> Source systems -> create
c. Select Database source system
d. Enter the database user name, password and connect string; for example Oracle enter the TNS name
e. Generate the data source using transaction RSDBC
f. Assign data source to info source
g. Maintain and activate communication structure and transfer rules
h. Create info package and load data

This is used in hierarchy authorization.

Defines the level of percentage change for realignment run will cause a reconstruction of aggregates.

a. you can load and activate ODS in parallel.
b. NoM table .
c. Secondary indexes are created in ODS objects itself .
d. Selective deletion.

An X will force the web report to display the variables entry screen.

a. I_T_FIELDS - list of transfer structure fields
b. I_T_DATA - internal table containing data for the master attributes; remember this contains all data
c. LUPDMODE - update mode
d. I_CHABASNM - basic characteristics
e. I_SOURCE - name of the info source

Using reporting agent you can fill values for a particular characteristic in the background; assume that every day you generate a detailed report on the top 10 products; to get the top 10 products you run another query with condition; so the parent query can be defined as a value set returning values for OMATERIAL.

The 3 SAP defined dimensions are…..
@Data packet dimension (P)… contains 3characteristics.a) request Id (b) Record type (c) Change run id
@Time dimension (T)….it contains time characteristics such as 0calmonth, 0calday etc
@Unit Dimension (U)…it contains basically amount and quantity related units.

This is tricky to explain but easy to implement once you know how.
Follow these steps (in later releases there is a wizard which takes you through the steps):
@In the terminating events view of the workflow step activate the "obsolete" event and give it a name.
@Specify a deadline period for the step.
@Specify a name for the event. This adds new branch from the step.
@Add a new step to the deadline path. This step must be of type "process control".
@Select the control "Make step obsolete" and use the search help to specify the workflow step that has the deadline. Only steps with obsolete paths defined will be displayed (see step 1).

a. it enables queries that do not contain a authorization relevant object that have been checked in info cube.
b. it allows summary data to be displayed if the user does not have access to detailed data; for example if you create 2 authorizations for one user one with Sales Org  and customers and second with sales org 1000 and customers  the user sees all customers for sales org 1000 and only summarized report for other sales org.

• Using this option we can write ABAP code for Units / Currencies conversion. If we enable this flag then unit of Key Figure appears in the ABAP code as an additional parameter. For example, we can convert units in Pounds to Kilos.

This is to group leaves together automatically; so when a new value is added to a characteristics it is added to the proper interval automatically.

Only one characteristic is allowed per line item dimension.

a. 1_VARTYP - variable type 1 — characteristic, 2- hierarchy node , 3-text, 4- formula, 5-hierarchy.
b. I_IOBJNM - name of the info object.

If you are defining prices then you may want to set “no aggregation” or you can define max, mm, sum; you can also define exception aggregation like first, last, etc; this is helpful in getting headcount; for example if you define a monthly inventory count key figure you want the count as of last day of the month.

If the flag is set, no master data is stored; this is only used as attribute for other characteristics; for example comments on a AR document.

If you this is not enough for you will probably want to write your own ABAP routines for generating the text and generating the attachments to go with the text.

Use the function group SO01 which contains functions of the form SO_*_API1 which are ideal for creating your own sophisticated messages. There are plenty of advantages of how these are used within the SAP system.

• Using BADI we can transform Open Hub Data according to the destination requirement.

a. new status only; this sends records of changed records; only ODS and cube can not be used.
b. additive delta — just change in key figures is sent; can be used in ODS and in cube.
