parameter is_layout-edit = ‘x’, in the function module

REUSE_ALV_GRID_DISPLAY.

Q8) How to display totals and subtotals in ALV?

Ans:- In field catalog, we have an option called DO_SUM. By using this

option, we can display totals and subtotals in ALV.

Enhancements:-

Q1)+ What is enhancement?

Ans:- SAP provided some loopholes to enhance the standard functionality.

These are called as enhancements. Through Enhancements, we can

add our own functionality to SAP’s standard business applications

without modifying the original application. We can create

enhancements for specific programs, screens and menus.

Q2)+ How can you implement enhancements?

(or)

What are the enhancement types?

Ans:- Depending on their enhancement approach, enhancements are divided

into 2 types. One is Customer exit and another type is BADIs. So, by

using customer exits and BADIs, we can implement enhancements.

Q3)+ What is the difference between customer exits & BADIs?

Ans:- Customer exits BADIs

1) In customer exits, we do 1) In BADIs, we do enhancements

enhancements in procedural in Object Oriented approach,

Approach, that is, By using that is by using Classes &

function modules. Methods.

2) Through customer exits, we can 2) Through BADIs, multiple

Implement enhancement only functionalities are possible.

One time.

Q4)+ How many types of user exits?

Ans:- Totally 3 types of user exits.

1)Menu exit: Menu exits are used to enhance the menu options. By

Using menu exits, we can add items to the pulldown

Menus in standard SAP applications.

2)Screen exit: Screen exits are used to enhance the screen. By using

Screen exits, we can add fields to screens in R/3 application.

3)Function Module exit: Function module exits add functionality to

R/3 applications. They play a key role in

both menu and screen exits. When you add

a new menu item to a standard pulldown

menu, you have to use a function module

exit to define the actions that should take

place once your menu is activated.

Q5)+ What is the disadvantage of menu exit?

Ans:- The disadvantage of menu exit is, we can not enhance menu options

Individually. For example, if we want to change a menu option from

‘Disable mode’ to ‘Enable mode’, irrespective of our requirement, all

the menu options are enabled. That is the disadvantage of menu Exit.

Q6)+ How to find out the user exit?

Ans:- à Execute Transaction code SE93 to find out the package

à Open the transaction in Display mode

à Double Click on ‘program’ to open it

à Go to à Attributes & find out the package

à execute transaction code ‘SMOD’ to find out the
enhancement from the already identified package

Then we can get the available enhancements.

Q7)+ How to implement the user exit?

Ans:- à execute transaction code ‘CMOD’

à provide ‘project name’ & click on ‘Create’.

à provide ‘Short text’ & Save it.

à Click on ‘Enhancement assignments’

à Here we can implement user exits.

Q8)+ How to find out the BADIs?

Ans:- BDCDATA is the structure used in BDC to Upload the data.

Q2)+ What are the update modes available in Call Transaction method?

Ans:- 2 update modes.

1) Asynchronous update :

*In this mode, the called transaction does not wait for any updates

It produces to be completed.

*Execution is faster when compared to synchronous update.

*It is not recommended for processing any larger amount of

Data why because error analysis and recovery is less convenient.

2) Synchronous update :

*In this mode, the called transaction waits for any updates that

It produces to be completed.

*Execution is slower when compared to Asynchronous update.

*The called transaction is able to return any update error

Messages. So, error analysis and recovery is much easier.

Q3)+ What are the display modes available in Call Transaction method?

Ans:- There are 3 display modes in Call Transaction method.

A - display All screens

All screens and the data that goes in them appear when we

Run the program.

N - No screens (Background processing)

All screens are processed invisibly, regardless of whether

there are errors or not. Control returns to the program as

soon as transaction processing is finished.

E - display Error screens only

The transaction goes into display mode as soon as an error

In one of the screens is detected. We can then correct the

error.

Q4)+ What is the default updation mode in Call Transaction method?

Ans:- Asynchronus updation is the default updation mode in call transaction

method. In Asynchronus updation, if an error occurs while updating The

database, It skips the error record and continues the updating process.

Q5)+ What is the default updation mode in Session method?

Ans:- Synchronus updation is the default updation mode in Session

Method. In Synchronus updation, if an error occurs while updating

The database, the updating process will be stopped at that point.

Q6)+ What are the function modules used in Session method?

Ans:- (explanation - BDC 1pg of session method)

3 function modules are used in session method.

1) BDC_OPEN_GROUP

2) BDC_INSERT

3) BDC_CLOSE_GROUP

Q7)+ What is the difference between Call Transaction method & Session

method?

Ans:- Call Transaction Session

1) In Call transaction method, data 1) Whereas in Session method,

Updation will take place at the a session will be created and

REPORTS:-

Q1)+ How to get the checkboxes side by side/in a single line?

(or)

How to place the selection screen elements in a single line?

Ans:- By default, each selection screen element is placed in a new line, and

More than one element can be placed in the same line also. That is, by

placing them in between the ‘SELECTION SCREEN BEGIN OF LINE’,

‘SELECTION SCREEN END OF LINE’.

Syn., SELECTION-SCREEN BEGIN OF BLOCK B1 WITH FRAME.

SELECTION-SCREEN BEGIN OF LINE.

*provide the selection screen elements

SELECTION-SCREEN END OF LINE.

SELECTION-SCREEN END OF BLOCK B1.

The elements within the same line loose the selection text by default. And

which can be provided through “SELECTION-SCREEN COMMENT”.

Syn., SELECTION-SCREEN BEGIN OF BLOCK B1 WITH FRAME.

SELECTION-SCREEN BEGIN OF LINE.

SELECTION-SCREEN COMMENT 5(10) TEXT-003.

*provide the selection screen elements

SELECTION-SCREEN END OF LINE.

SELECTION-SCREEN END OF BLOCK B1.

Q2)+ How to create the text for check boxes?

(or)

How to provide user-friendly descriptions for selection screen elements?

Ans:- To provide user-friendly descriptions for selection screen elements,

Path: Go to àText elements à Selection texts

Enter the text, save it & activate it.

Q3)+ How to disable a field on selection screen?

Ans:- We can disable a field on selection screen, by using “AT SELECTION

SCREEN OUTPUT” event. In this event, loop the screen and in the loop,

We have to keep SCREEN-INPUT = ‘0’ for that particular field.

Q4)+ How to validate the entered values of the selection-screen?

Ans:- By using the event “AT SELECTION SCREEN”, we can validate

the entered values of the selection-screen. This event triggers before

leaving the selection-screen and this event is not only used to validate

the input of the selection-screen but also used to display user friendly

messages on the selection-screen itself.

The input is valid only when there is at least one record found in

The master data. If a record found, then SY-SUBRC value becomes

‘0’, if recode not found, then its value becomes <> ‘0’. In this way,

we can validate the entered values of the selection-screen.

Q5)+ What are the events in reports?

Ans:- 1) INITIALIZATION

2) AT SELECTION SCREEN OUTPUT

3) AT SELECTION SCREEN ON VALUE REQUEST

4) AT SELECTION SCREEN

5) START OF SELECTION

6) END OF SELECTION

7) TOP-OF-PAGE

8) END-OF-PAGE

9) AT LINE SELECTION

10) AT USER COMMAND

Ans:- 1) SY-LISEL

2) HIDE

3) GET CURSOR

Q7)+ How many secondary lists can we create in reports?

Ans:- 20 secondary lists.

Q8)+ How many types of messages we have in reports?

Ans:- 1) Error message (E)

2) Warning message (W)

3) Information message (I)

4) Abort message (X)

5) Termination message (A)

6) Status message (s)

Q9)+ In how many ways, can we display messages?

Ans:- 2 ways.

1) MESSAGE E001(message class).

2) MESSAGE ‘message text’ type ‘E’.

Q10)+How to create message class?

Ans:- We can create message class, by using transaction code SE91.

Q11)+How to validate the group of fields?

Ans:- We can validate the group of fields by using ‘chain’ and ‘endchain’.

That is, If the validation has to be done for more than one field, then, in

That situation, those fields are placed between ‘chain’ and ‘endchain’.

Q12) What are the control break events?

Ans:- 1) AT FIRST: to display the starting text

2) AT LAST: to display the ending text

3) AT NEW: to display the starting text of the subgroup

4) AT END: to display the ending text of the subgroup

5) ON CHANGE OF:

       AT FIRST---->this is used for system field heading in

                      ABAP  program.

         AT NEW------>this is used to display the fields.

         AT END------>this is used for row-wise calculation i.e,
