What is lock Object ?
Lock Object is a relationship defined in the Data Dictionary
between a main table and
possible secondary tables
lock object is used to prevent the several users to access the
samedata record at the same time.
Select option work like _____________on Selection Screen ?
The system treats select-options like an internal table.
This table will have four
columns - sign high low and option.This is used to set teh
attributes on the select
Which sysgtem variable have current value during execution ?
BDC OK_code
What is the main point while using controll bareak in internal
table ?
when you are using control break commands.internal table must be
sorted with keyfield.and control-break commands must be used in
between the LOOP and ENDLOOP
only.
The Precautions taken care while using Control Break Statements
are:
1.Sort theinternal table before we use Control Break
Statements.
2.We Must compulsory place
the Control Break Statements with in loop ....endloop.
EX:(Sample Code)
sortitab by vbeln.
loop at itab.
at first.
write:/ 'VBELN'.
endat.
at new
vbeln.
endat.
at end of vbeln.
endat.
at last.
endat.
endat.
endloop.
if we want some more informationplz mail to my id

We are using Control break statements for calculations perfus.
Before using control breakstatement should be sort and these
statements should be used in between loop and
endloop except on change off
What is Field sysmbol ?
You can use field symbols to make the program more dynamic. In
this exanmple the
name of a table control is substituted
by a field symbol. Thus you cal call the formwith any internal
table, using the name of the tabl?control as a parameter.
Example
form insert_row
using p_tc_name.
field-
symbols type cxtab_control. "Table control
assign (p_tc_name) to.
* insert 100 lines in table control
-lines =100.
Field Symbol is very much conceptually similar with Pointers in
c language.

STOP.
Effect :The statement STOP is only to be used in executable
programs
EXIT.
Effect :If the EXIT statement is executed outside of
a loop, it will immediately terminate the current processing
block.
BACK.
Effect : This statement positions the list cursor on the first
position of the first line
in a logical unit.
So "Cancle" is not an exit command
Explain about roll area , Dispatcher, ABAP-Processor.
Dispatcher recieves the request from client and assigns the
request to one of the workprocess.
Roll area: Each workprocess works in a particular memory that
memory is known as Role Area, which consists of User context and
sessiondata.
ABAP- Processor
How do you connect to the remote server if you are working from
the office for the client in remote place.
WAS web application server or ITS are generally used for this
purpose. If you are sittingat your office with a server which is in
the system and the other server is at the clients
place you can generate IDOC, intermidiate documents which carry
the data you want totransfer or the documents you want to transfer,
these IDOC are interpretted by the
system at the recieving end with the message class with which it
is bound with. If youwant to logon a system which is very
distant..then remote login can be used this
depends on the internet speed.
How do you see the authorization checks
In the interactive reporting, the first event you enter is
"initialisation" that is used for the
authorization checks , mainly the administrator is responsible
for that purposes and heonly has the authority for that.
What is difference between dialog program and a report?
using reports
we can dispaly the data
insert and modify the data
* its executable program
where as in dialog programming
we can create our own screens and transactions
we can't execute directly this
Using Report: we can dispaly, insert and modify the data.Its
executable program.
Dialog Programming: we can create our own screens and
transactions.we can't executedirectly this.
