Sap Reports Interview Questions and Answers
What is LDB?
Logical Database is an ABAP program which retrieves data
from various tables
Which are interrelated and provides a read only view of
the data.
What are the EVENTS in Report Program? What are EVENTS
In Interactive Report and Explain?
Classical Report Events are
LOAD OF PROGRAM.INITIALIZATION.
AT SELECTION-SCREEN.START-OF-SELECTION.
TOP-OF-PAGE.END-OF-PAGE.
END-OF-SELECTION.
Interactive events are
AT LINE-SELECTION.
AT USER-COMMAND.
TOP-OF-PAGE DURING LINE-SELECTION.
AT LINE-SELECTION:Allows the user to interact with the
lists.
AT USER-COMMAND:USed for handling Push buttons.
SET PF-STATUS:Provides User Interface.
What are the various techniques of BDC?
call transaction
session method
direct input method
What is SQL Trace?
SQL Tracer is a tool used to measure the performance of
ABAP program.
T.code :st05
What is LUW?
It is a span of time during which database records are
updated either
commit or rollback.
Have you worked with reading and writing data on to
files?
YES, open dataset <filename> for output. read dataset
<filename> from itab. close dataset <filename>.
Have you created tables in SAP? What are client
dependent and independent tables? How do you create
independent tables?
Tables which are having MANDT field is called as client
dependent tables. Tables which are not having MANDT
field is called as client dependent tables.
Have you used SM30 and SM31 transactions?
sm30 is used to view the ' Call Up View Maintenance '
and SM31 is to view the ' Table maintenance ' with
How many dictionary objects are there and list all
Available Dictionary Objects are Domains, Viwes, Match
Codes, Lock Objects, Structures, Data Elements, Intenal
Types.
What is the difference between transparent and non
transparent database tables?
Transparent tables have 1 - 1 cardinality b/w Data
Dictionary and Database, and non transparent ( Cluster
and Pooled) tables have Many - 1 cardinality.
Transparent table can access with using OPen & NAtive
SQL stmts where as Nontransparent only OPen Sql.
Transparent trables can store Table relevent data and
non transparent tables can store system data/
application data based on the transparent tables
What is meant by BDC. How many methods of BDC are there?
BDC -> BATCH DATA COMMUNICATION.
METHODS OF BDC-> Direct Input method, Batch Input
Session method, Call transaction method.
What are the difference between table controls and step
loops in dialog programming?
1. Function modules use a special screen to define the
parameters where as subroutines use the same ABAP/4
editor to define its parameters.
2. Tables work area can be commonly shared by calling
program and subroutine where as function modules do not
share commonly.
3. Calling a function module syntax (Call function.) is
different from calling a subroutine syntax (perform….).
4. With raise statement user can exit from a function
module where as exit is used in subroutines.
What is ALE, IDOC , EDI , RFC. Explain briefly.
ALE: application linking enabling
IDOC: intermediatary documents
EDI: electronic data interchange
RFC: remote function call
What is a binary search?
Binary Search is used in internal table for searching
the records. its means record searched one by one from
top & bottom both side.so its a easy nd fast way to find
the record.bt pointer searching is better.
Types of User Exits, what kind of work is done on these
exits?
File Exit, Menu Exit, Function Exit.
How will you find out where the user exits are
available?
CMOD : This transaction allows you to create a PROJECT
by identifying its ENHANCEMENT(S). After determining all
of the ENHANCEMENTS that are part of the PROJECT, you
will have to activate the PROJECT. You will still need
to code your user-exit; therefore, you may want to wait
until this step is completed before activating the
PROJECT.
§SMOD : This transaction allows you to create an
ENHANCEMENT, which you will include in a PROJECT, by
identifying its COMPONENT(S). In the case where SAP has
already created an ENHANCEMENT for its pre-defined
user-exits, you will not need to use transaction SMOD;
instead, you should just use transaction CMOD.
Have you created any transactions?
Yes,
We can use TC SE93 for creating our own transaction
code.
Difference between Table-Controls and Step-loops?
Table controls are modified / mproved versions of step
loops.
in controls we can do,
horizontal scrolling,
vertical scrolling,
scrolling in a perticular field,
resize the table,
can save the settings for future use,
can make selective columns editable,....etc
these things are not possible with step loops.
step loops are controlled by loop-endloop statements.
Import and Export
ABAP memory is a memory area that all ABAP programs
within the same internal session can access using the
EXPORT and IMPORT statements. Data within this area
remains intact during a whole sequence of program calls.
To pass data to a program which you are calling, the
data needs to be placed in ABAP memory before the call
is made. The internal session of the called program then
replaces that of the calling program. The program called
can then read from the ABAP memory. If control is then
returned to the program which made the initial call, the
same process operates in reverse.
How many interactive reports did you write?
In an Interactive Report, user can define maximum 20
secondary lists.
What is an “Unpack command”
UNPACK field1TO field2 .Unpacks the packed field field1
and places it in the field field2 with leading zeros. If
field2 is too short, it is truncated on the left.
