SAP ABAP Project Real time Questions
Dear ABAPER's this post gives the list of SAP ABAP Project Real time Questions and Answers which are asked in various interviews by the top MNC companies. This post definitely will help the ABAPers who are going to attend interviews with 2+ and 3+ experience. Dear ABAPers refer this post for more details.
Q) What is Extended Program Check(EPC) ?
Ans: Doing an
EPC would ensure the removal of mistakles we tend to overlook when we do the
code-walk-through or initial testing.
The program,
although syntactically correct may have some unnecessary code, unused variables
etc.
EPC,
advantages are
With the help
of EPC we can find out the
Absolete(Out
Dated) stmts
Authorization
checks
Problematic
Statements
Any hidden
messages
through this
we can increase the consistency of the program and the performance can also be
increased.
For this
Execute SE38 then program then check a EPC.
Difference
Between EPC and Code Inspector :
Code
inspector is the tool that gives you a picture of what could be the pain points
in terms of performance of the program. It tells you the execution time, etc,
that determine the performance of the program.
SCI Checks
for the following:
Syntactical
check
Security
check
Performance
check
Search
Function
Extended
Program Check give information of the possible errors that can cause a short
dump of the program during execution like Call function interface errors,
Program interface errors, etc. Also info about the translations and texts is
given in it
Extended
Program check
Any
obsololete stmnt used or not
Syntactical
check
3)Any unused
code in the program like routines
Q) What is ASAP Methodology?
Ans : The ASAP solution was developed to ensure the
successful, on-time delivery of a project. SAP delivers the AcceleratedSAP
(ASAP) methodology for project management and system implementation.
Developed by SAP to
optimize the success of implementing the SAP Business Suite, ASAP streamlines
the implementation by providing templates, methods, tools, and accelerators
that have been built on the success of thousands of previous SAP
implementations.
The ASAP methodology
adheres to a specific road map that addresses the following five general
phases:
1. Project Preparation,
in which the project team is identified and mobilized, the project standards
are defined, and the project work environment is set up;
2. Blueprint, in which
the business processes are defined and the business blueprint document is
designed;
3. Realization, in which
the system is configured, knowledge transfer occurs, extensive unit testing is
completed, and data mappings and data requirements for migration are
defined;
4. Final Preparation, in
which final integration testing, stress testing, and conversion testing are
conducted, and all end users are trained; and
5. Go-Live and Support,
in which the data is migrated from the legacy systems, the new system is
activated, and post-implementation support is provided.
ASAP incorporates
standard design templates and accelerators covering every functional area
within the system, as well as supporting all implementation processes.
Q). What is Code
Inspector?
Ans : The Code Inspector (transaction code SCI) is a
tool for checking Repository objects regarding performance, security, syntax,
and adherence to name conventions.
Using
the Code Inspector (transaction code SCI),
you can check individual objects or Set Of Objects for performance, security,
syntax, and adherence to name conventions.
There are messages that
are always important, that always need action,like:
-> performance error
and warning messages regarding missing index
support;
-> select single
statements without fully qualified key
-> calling functions
with a wrong interface
(will lead to run time errors)
-> submitting
programs and calling transactions that do not exist
-> using obsolete
statements (like on change) and functions (like ws_download)
-> subroutines with
not typed formal parameters
-> bad error
handling: no checking of return codes after SQL statements,
CALL FUNCTION statements etc
-> inefficient
internal table use (sequential access to internal tables will lead to
serious performance problems if the internal table is large and the access is
done repeatedly)
Q) What is OSS
Note?
Ans : Problems could not be solved by both of the
above, are referred to Online Service Support (OSS) of SAP Itself.
SAP tries to solve the
Problem, sometimes by providing the perfect OSS Notes, fits to the error and
rarely SAP logs into our Servers (via remote log-on)for post mortem the
problem.
(The Medical check-up
client, connections, Login id and Passwords stuff are to be provided to SAP
whenever they need or at the time of opening OSS Message.)
There are lots of OSS
Notes on each issue, SAP Top Notes and Notes explaining about the process of
raising a OSS Message.
Sometimes SAP Charges to
the client / Service company depending on the Agreement made at the time of
buying License from SAP.
Note :
We Can check all
the available OSS Notes through SAP Transaction SNOTE.
