Answer 1

Which client number you use for the current
project?
It depends on the client specifications.
You are running a report. It is taking long time for
execution. What steps will you do to reduce the
execution time.
Performance analysys can be done. There are some standards in coding also, for example "select matnr mbrsh meins from mara" is efficient than select *....
After running a BDC program in background, next
day morning when you see the results, few records
are not updated(error records). What will you do
then?
The error recors can be analysed using sm 35 and can change the code accordingly and run the process for error records( mode E )
You are given functional specs for a BDC program
and you need to decide whether to write a method
call transaction or a session. How u will decide?
Usually method will be described in functional specs. If not, it depends on the no. of records.
What is the difference between report and script?
we can not have the formating options in the reports.
what are the differences between scripts & smart
forms?
•     SAP Scripts are client dependent whereas Smartforms are client independent.
•     SAP Scripts require a driver program to display the output whereas in smartforms the form routines can be written so that it is standalone.
•     An integrated Form Builder helps to design Smartforms more easily than SAP Scripts
•     An Table Painter and Smartstyles to assist in building up the smartforms
•     On activation a function module is generated for Smartforms
•     It is possible to create a Smartform without a main window
•     Smartforms generates XML output which can be viewed through the web
•     Multiple page formats is possible in smartforms
what are enhancements?
is the concept of adding functionalities to the existing programs.
what are user-exits?
It is older version of enhancements
what is badi?
Object oriented concepts of user exits
what is the difference between user-exit & BADIs?
mentioned above
what is the difference between user-exit &
customer-exit?
customer exit is a part of user exit.( we have field exits etc  along with these)
how do you get functional specs when you are
assigned some object? (specs through email..??)
Usually through mails
How do you write technical specs?
It is like blue print of the program flow ( it looks like algorithm)
How do you write UTP?(unit test plan)
what is the difference betn end-of-page and end-of-selection?
end-of-page is used to trigger footer (usually), end-of-selection is user to mention the close of start-of-selection. ( it is not mandatory but, good programming practice).
if you write a write statement after end-of-selection, will that be triggered?
If the statement is not under the event, it wont.
how to create a button in selection screen?
selection-screen pushbutton is the event.
how to add a gui status in a selection screen?
can you call a bdc program from a report? how?
the program itself is a report, usually we call the screens from the report.
can you call a transaction from a report? how?
yes. Using call transaction <tcode>.
what are ALV reports? how they are different from normal reports?
Redirecting the output data into grid controls. We can drag and drop the fields as we wish and it looks rich comparitively.
what are the main events that are used in an ALV report?
Same as classical reports.
can you create an internal table dynamically?(at run time
what is the role of ST05 in performance tuning?
Cheers.
