51. What are the techniques involved in using SAP supplied programs?
Do you prefer to write your own programs to load master data? Why?
52. What are logical databases? What are the advantages/disadvantages of logical databases?
ANS:-
To read data from a database tables we use logical database.
A logical database provides read-only access to a group of related tables to an ABAP/4 program.
adv:-
The programmer need not worry about the primary key for each table.Because Logical database knows how the different tables relate to each other,and can issue the SELECT command with proper where clause to retrieve the data.
i)An easy-to-use standard user interface.
ii)check functions which check that user input is complete,correct,and plausible.
iii)meaningful data selection.
iv)central authorization checks for database accesses.
v)good read access performance while retaining the hierarchical data view determined by the application logic.
disadv:-
i)If you donot specify a logical database in the program attributes,the GET events never occur.
ii)There is no ENDGET command,so the code block associated with an event ends with the next event
statement (such as another GET or an END-OF-SELECTION).

ans:-
we will look into the error log file (SM35).
61. What do you do with errors in BDC batch sessions?
ANS:-
We look into the list of incorrect session and process it again. To correct incorrect session we analyize the session to determine which screen and value produced the error.For small errors in data we correct them interactively otherwise
modify batch input program that has generated the session or many times even the datafile.

71. What are IDOCs?
ans:-
IDOCs are intermediate documents to hold the messages as a container.
72. What are screen painter? menu painter? Gui status? ..etc.
ans:-
dynpro - flow logic + screens.
menu painter -
GUI Status - It is subset of the interface elements(title bar,menu bar,standard tool bar,push buttons) used for a certain screen.
The status comprises those elements that are currently needed by the transaction.
73. What is screen flow logic? What are the sections in it? Explain PAI and PBO.
ans:-
The control statements that control the screen flow.
PBO - This event is triggered before the screen is displayed.
PAI - This event is responsible for processing of screen after the user enters the data and clicks the pushbutton.
74. Overall how do you write transaction programs in SAP?
ans:-
Create program-SE93-create transcode-Run it from command field.

76. What are step loops? How do you program pagedown pageup in step loops?
ans:-
step loops are repeated blocks of field in a screen.
77. Is ABAP a GUI language?
ANS:-

What is the XXXXXTOP program?
ans:-
ABAP/4 program.
DYNPRO
79. What are the include programs?
ANS:-
When the same sequence of statements in several programs are to be written repeadly they are coded in include programs (External programs) and are included in ABAP/4 programs.

ANS:-
Should start with Y or Z.
84. How do you find if a logical database exists for your program requrements?
ans:-
SLDB-F4.
85. How do you find the tables to report from when the user just tell you the transaction he uses? And all the underlying data is from SAP structures?
ans:-
Transcode is entered in command field to open the table.Utilities-Table contents-display.

ans:-
91. What are the different elements in layout sets?
ans:-
PAGES,Page windows,Header,Paragraph,Character String,Windows.
92. Can you use if then else, perform ..etc statements in sap script?

ANS:-
The application layer of an R/3 System is made up of the application servers and the message server. Application programs in an R/3 System are run on application servers.

For cardinality one out of two (domain or data element) should be the same for Ztest1 and Ztest2 tables. M:N
Cardinality specifies the number of dependent(Target) and independent (source) entities which can be in a relationship.
