Knowledge of SAP ABAP Test Answers
·
1. ABAP has built-in types like C, I,
N, STRING, or X. If you use these types for defining data objects, which of the
following statements are correct?
Answers:
• If you want to
define a two-byte integer data object, you use the follow-ing syntax: DATA
xyz(2) TYPE i.
• If you create a
data object without explicitly specifying its type, it will become type C with
length 1.
• If you define a
data object with type D, two or four digits will be re-served for the year,
depending on the user's settings.
• A data object of type
STRING has a fixed length that will automatically be set when the first value
is assigned to this data object. This length cannot be adjusted thereafter.
2. During an upgrade project to SAP NetWeaver
7.0, you are asked for a strategy to convert the implemented classic BAdIs to
the new BAdI type.
What do you recommend?
Answers:
• Perform the
migration of customer BAdIs and BAdIs that are provided by SAP With the
available migration tool.
• Use the procedure for
semi-automatic migration because of existing differences between classic and
new BAdIs.
• Perform a
completely automated migration of all existing classic BAdIs with the available
migration tool.
• Create new
BAdIs because a conversion of classic BAdIs is not foreseen.
3. Among the most frequently used enhancement
concepts in ABAP, you find customer exits. Which of the following statements
about customer exits are correct?
Answers:
• If a customer
exit is not implemented, the program offering this customer exit will dump
(terminate abnormally) at runtime.
• Within one SAP
system, a customer exit can have a maximum of one implementation.
• Within one client of an
SAP system, a customer exit can have multiple implementations.
• Once a customer
exit has been implemented in an SAP system, the implementation can be changed,
but it cannot be deactivated any more.

What do you recommend to solve this problem?
Answers:
• Modify all dynpros that
use data from the plausibility checks.
• Implement new
plausibility checks for every dynpro change.
• Implement the
same plausibility checks in the User Exit "before save".
• Implement an
additional program to correct the wrong data field values.

screen (dynpro).
• By default, a
column header will be taken from the data element which is used for specifying
the type of the column.
• When a report
with an ALV Grid Control is executed in background processing, the program will
terminate abnormally since controls can-not be addressed in background
processing.
• The ALV display
is automatically refreshed when the data in the data-base table is changed.

installation is independent from the existing installation and all functions of
the package will be activated at once.
• The
installation is done via OSS so that the projects themselves do not require
administrative knowledge.
• The
installation of a whole package is required, but it is possible to activate
only parts of it.
26. You analyze the complexity of a
customer-specific program to determine the expected maintenance efforts.

28. Internal tables are used in ABAP to store
mass data. Which of the following statements about the relationships between
internal tables and database tables are correct?
Answers:
• An internal
table can be linked to a database table so that the content of the internal
table is updated automatically as soon as the content of the database table
changes.
• A data base
table XYZ can be used for the definition of an internal table like this: DATA
itab TYPE TABLE OF xyz.
• A data base
table in the Dictionary can be defined with reference to an internal table from
an ABAP program.

huge number of rows to be dealt with in a program, it might improve the
program's performance if you define a database table in the program instead of
an internal table.
