Sap Reports Interview Questions and Answers
What are the SET Parameter and GET Parameter?
To use parameter IDs, you need to “set” (store) values
in the global memory area and then “get” (retrieve)
values from this parameter ID memory area. §IIn the case
of an online program, you will “set” values from screen
fields and you will “get” these values for screen
fields. §YYou can perform this “set/get” function two
ways: § Use the ABAP statements “SET PARAMETER ID” and
“GET PARAMETER ID”. § Use the field attributes “SPA” and
“GPA” . §RRemember that parameter IDs can only be used
with ABAP Dictionary fields because parameter IDs are
linked to data elements. The appropriate data elements
must have a parameter IDs for this “set/get” function to
work.
What are Text Elements?
Text elements makes program easier to maintain program
texts in different languages.
These are used for maintainig list
headers,selectiontexts in programs
What is an Interactive Report?
An Interactive report allows the user to participate in
retrieving and present data at each level.while
classical report doesn't have access to interact
What are Layout set Elements?
layout set elements are
1.header 2.peragraph formats 3. character formats 4.
windows 5. pages 6.page windows
Distinguish between setscreen and call screen?
In the case of setscreen the entire processing of the
current screen takes place and then the system branches
out to next screen.if u want to branch out to the next
screen without processing the current screen then LEAVE
SCREEN should be used along with SET SCREEN.
CALL SCREEN is usually used for pop up screens.
What is ABAP Memory and SAP Memory?
Answer1;
SAP memory is a memory area to which all main sessions
within a SAPgui have access. You can use SAP memory
either to pass data from one program to another within a
session, or to pass data from one session to another.
Application programs that use SAP memory must do so
using SPA/GPA parameters .
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.
Answer2;
1. SAP memory is for cross-transaction Applications and
ABAP/4 memory is transaction-specific.
2. The SAP memory, otherwise known as the global memory,
is available to a user during the entire duration of a
terminal session. Its contents are retained across
transaction boundaries as well as external and internal
sessions. The contents of the ABAP/4 memory are retained
only during the lifetime of an external session. You can
retain or pass data across internal sessions.
3. The SET PARAMETER and GET PARAMETER statements allow
you to write to, or read from, the SAP memory. The
EXPORT TO MEMORY and IMPORT FROM MEMORY statements allow
you to write data to, or read data from, the ABAP
memory.
Explain Check Table and Value Table ?
check tabke works at table level and value table works
at domain level.
check table is nothing but master table that u will
create with valid set of values.
value table it provides the list of values and it will
automatically proposed as a check table while creating
foreing key relationship
How many types of Standard Internal Tables?
- STANDARD TABLE:
The key is, by default, set to NON-UNIQUE. You may not
use
the UNIQUE addition.
- SORTED TABLE:
Unlike stadard tables, sorted table have no default
setting
for the uniqueness attribute. If you do not specify
either
UNIQUE or NON-UNIQUE, the system defines a generic table
type, where uniqueness is irrelevant. You can use
generic
types to specify the type of generic subroutine
parameters.
- HASHED TABLE:
Hashed tables have no default setting. You must use the
UNIQUE addition with hashed tables. You may not use
NON-UNIQUE.
What is Refresh in Internal Table?
'Refresh' is the keyworld which clears the contents of
an internal table body.
What is the Difference Between Collect and Sum?
COLLECT allows you to create unique or summarized
datasets. The system first tries to find a table entry
corresponding to the table key. The key values are taken
either from the header line of the internal table itab,
or from the explicitly-specified work area.
If the system finds an entry, the numeric fields that
are not part of the table key (see ABAP number types)
are added to the sum total of the existing entries. If
it does not find an entry, the system creates a new
entry instead.
The way in which the system finds the entries depends on
the type of the internal table:
- STANDARD TABLE:
The system creates a temporary hash administration for
the table to find the entries. This means that the
runtime required to find them does not depend on the
number of table entries. The administration is
temporary, since it is invalidated by operations like
DELETE, INSERT, MODIFY, SORT, ...). A subsequent COLLECT
is then no longer independent of the table size, because
the system has to use a linear search to find entries.
For this reason, you should only use COLLECT to fill
standard tables.
- SORTED TABLE:
The system uses a binary search to find the entries.
There is a logarithmic relationship between the number
of table entries and the search time.
What are the ways of creating Tables?
There are two ways to create table
1) top-down approach
2) bottom-up approach
What are Function Modules?
Answer1:
Function modules is a extranal subroutine.we can call it
to outside the program.its a mini program. its used for
redues the coding,easy to find error.
Answer2:
Function modules is like a small program (is not a
suboutine because sub-routines are not standalone
objects-i.e we cannot execute them alone) which are
similar to 'functions' in C.
We can pass the varible and get the return values even
with out knowing what is happening in its code.
They are standalone programs-i.e.we can debug and
execute them alone unlike subroutines and macros and
includes.
What is CAT?
"CAT" Computer Aided Test Tool. Used to create test
cases for application testing purposes.
