Details About Smart forms in SAP ABAP

Details About Smart forms in SAP ABAP

Smart forms are used to design the business documents such as purchase order, sales order, 

invoice, Performa etc.

Smart forms are introduced from 4.6c version onwards. It also supports output mode as ‗EMAIL‘.

Components of Smart forms:

1. Smart form layout.

2. Function module.

3. Print layout.

Components of the smart forms layout:

1. Global settings.

2. Pages and windows.

Components of Global settings:

1. Form attributes

2. Form interface

3. Global definition

Form attributes:

Form attributes contain header information i.e.

Form name

Language 

Page format 

Created by…………..

Form interface: this is used to declare the variables, work area and internal tables which we need to 

transfer the data from print program to layout.

Global definition: this is used to declare the variables, work-area and internal table which are used to 

implement the logic in the layout.

PAGES: page is the physical area where we place the window. We can‘t print the text in the page.

WINDOWS: we can place the same window in ‗n‘ number of pages but we can‘t print the data directly 

on the window.

Procedure of Smart Form:

1. Based on the client requirement we design the smart form layout by using SMARTFORMS t-

code.

2. After activating the smart form it generates a function module.

3. Based on the function module we develop the print program.

NOTE: Printing the data on the page window is always through symbols.

There are four types of symbols.

1. Program symbols

2. System symbols

3. Standard symbols

4. Text symbols.

Each symbol starts with ‗&‘ ends with ‗&‘.

Differences between function module & subroutine in SAP ABAP.

Differences between function module & subroutine in SAP ABAP. 

 Function module

 Subroutine 

1. Function modules are global, i.e., 

we can access the function module 

with in the server as well as outside 

the server also.

2. We can test the function module 

independently.

3. We can handle the errors in 

function module.

4. Function modules are defined by 

using SE37 transaction code.

1. Subroutines are local, i.e., we can 

access the subroutine with in the 

server only.

2. We can‘t test the subroutine 

independently without calling the 

subroutine.

3. We can‘t handle the errors in 

Subroutine.

4. Subroutines are defined by using 

SE38 transaction code.

Steps to create function module:-

 Execute SE37.

 Provide your function module name.

 Create.

 Provide function group name & short description.

 Save.

Differences between Macros & Subroutines:-

Differences between Macros & Subroutines:-

 Macros

 Subroutines

1. In macro definition should be the 

first & the calling should be the next. 

2. The definition of the macro as 

well as the calling of the macro in 

the same program.

3. Macros can take up to 9 place 

holders. 

4. We can place any executable 

statements after the definition of the 

macro.

5. Macros are used in HR ABAP.

1. In subroutine calling should be the 

first & definition should be the next.

2. The definition of the subroutine as 

well as the calling of the subroutine 

may or may not be in the same 

program.

3. Subroutines can take any number 

of place holders.

4. We can‘t place any executable 

statements after the definition of the 

macro.

5. Subroutines are used in both 

ABAP & HR ABAP.

Differences between single select &select up to 1 in SAP ABAP.

Differences between single select &select up to 1 rows:- 

 Select single

 Select up to 1 rows 

1. It always retrieves only one record 

at a time.

2. Here we must pass entire primary 

key combination in the where 

condition.

3. This is used to retrieve particular 

record.

Syntax:-

1. It always retrieves only one 

record.

2. Enough to pass a part of key 

combination in the where condition. 

It always picks the first record 

among the matched records.

3. This is used for validation.

This is how we have to design the page. The no of windows in the page depends on page layout. Now I want to keep a logo in one of the windows of page. For that we first have to upload the logo into sap. For uploading logo into sap the T-code is SE78.

      It is used to upload only Bitmap images.

SCRIPTS IN SAP ABAP.

 SCRIPTS IN SAP ABAP. 

It is the integrated text management system of SAP. The output of  scripts and normal report will be same. But formatting is very easy using scripts. Usually scripts are used for external purpose and reports are used for internal purpose. When specific format is required in output we go for scripts.

In scripts we require layout set and print program. Layout set is used for designing the output. That is page designing is done here. For this Transaction code is SE71 (form painter).

Print program is used for writing the logic to get the data from data base. It is an executable program which is written in SE38 T-code.

Attributes of form painter (SE71)

Header

Pages

Windows

Page windows

Paragraph Formats

Character Formats

HEADER:- It contains Basic settings and administrative data. Administrative data gives history of the form and basic settings gives technical information about the form.

PAGES:- It is a logical memory area where output is formatted. It is a repository of pages.

WINDOWS:- I t is a place on the page where output or data is formatted. Page has to be divided into windows in order to hold the output. We cant format the output outside the windows. Windows  is repository of windows.

Paragraph formats and Character formats are used for alignment or beautifying the output.

SESSION METHOD IN SAP ABAP. 

Differences between call transaction and session method.

In call transaction updation is immediate but in session method updation is not immediate.

In call transaction user has to handle errors but in session system handles the errors.

In call transaction updation can be synchronous or asynchronous or local but in session method updation by default synchronous.

Call transaction returns sy-subrc value but session will not return sy-subrc value.

In session method the data will be stored intermediately in session. After processing the session only the data will be moved into data base. For processing the session the T-code is SM35.

SESSION:- It is an intermediate memory area where data with flow logic is stored. It is intermediate between internal table and data base table. A session can not be processed on the date on which it is created. A session can not be processed if it is processed successfully. If session is having error it can be processed any number of times.

In session method we have to use 3 function modules.

BDC_OPEN_GROUP

BDC_INSERT

BDC_CLOSE_GROUP

BDC_OPEN_GROUP: -  This function module is used to create a session with particular name.

BDC_INSERT:-  This function module is used to move flow logic and data into session. This function module should be called between the loop and endloop after recording steps.

BDC_CLOSE_GROUP:- This function module should be used to close the session. If this function module is not used the session will be created but we cant process the session.

CONTROL STATEMENTS IN SAP ABAP

 CONTROL STATEMENTS IN SAP ABAP. 

Control statements are nothing but loops. The property of the loop is to rotate by it self until loop is terminated. There are 4 types of control statements in SAP. They are

DO.

..

..

ENDDO.

DO N  TIMES.

..

..

ENDDO.

WHILE  <CONDITION>.

..

..

ENDWHILE.

CASE  <VARIABLE>.

WHEN <VALUE1>.

 ..

 ..

WHEN <VALUE2>.

 ..

WHEN OTHERS.

 ..

ENDCASE.

Exit statement is used to terminate the loop. SY-INDEX is a system variable which gives present loop iteration number. These both things we use in coming program to see how they act in the loop.

SMART FORMS IN SAP ABAP

 SMART FORMS IN SAP ABAP. 

It is enhanced version to SAP scripts. Transaction code is smartforms.

First we discuss about the differences scripts and smart forms.

Scripts are client dependent but smart forms are client independent.

Scripts are not self executable i.e. print program is compulsory, but smart forms are self executable. On executing the smart form system generates function module.

We can not write the logic in scripts but we can write the logic in smart forms.

Main window is compulsory in scripts but it is optional in smart forms.

Background logo is not possible in scripts but it is possible in smart forms.

There are character and paragraph formats in scripts but there are no character and  paragraph formats in smart forms

Labels are present in scripts but no labels in smart forms.

When ever you enter into smartforms under global settings you get three things.

Form attributes

Form interface

Global definitions

FORM ATTRIBUTES:-  It gives the history and technical attributes of smart form

FORM INTERFACE: - The variables that are needed to be populated at run time should be declared here.

GLOBAL DEFINITIONS:-  The variables that are needed in the smart form should be declared here. 

  

Now we discuss about the steps in creation of smart forms.

T-code smartforms

Press create button

To create logo window right click o page create( Graphic

Give the logo name

The variables that are needed to be populated at run time should be declared under form interface

What is ENHANCEMENTS in SAP.

 ENHANCEMENTS in SAP ABAP. 

These are used to add extra intelligence to SAP standard programs to suit the business requirements. If we want to add extra code to SAP standard programs, if we go for change mode system asks for access key. Instead of this, SAP has provided hooks where we can write the code. These hooks are enhancement spots. If a code is written in theses spots along with the normal program the code written in these spots is also executed. There are two ways to enhance the SAP standard code.

User Exits

BADIS (Business Addins)

If user exits are used one time in any project it can not be reused. But Badis can 

be used any no of times.

There are 4 types user exits.

Function module exit

Field exit

screen exit

Menu exit

Exits are defined at package level. So we want to enhance any T-code first we 

have to find out the package for that T-code. Then we have to find out the exits present in that package. For finding the exits present in a package we have to use SMOD T-code. After finding the suitable exit for writing the code we have to use CMOD T-code.

USER EXITS I N SAP ABAP.

USER EXITS IN SAP ABAP. 

There are four types of USER EXITS

Function Module exits

Screen exits

Menu exits

Fields exits

Function Module exits:

In this we will use FUNCTION MODULE, to enhance, SAP standard program.

Screen exits:

They are used to add extra FIELDS in SAP standard screens.

Menu exits:

It is used to add extra MENU ITEMS to SAP standard screens.

Field exits:

It is used to add extra VALIDATIONS to SAP standard screen fields

TYPES OF TABLES IN SAP ABA

TYPES OF TABLES IN SAP ABAP. 

There are three types of tables.

1. Transparent Tables

2. Clustered Tables

3. Pooled Tables.

TRANSPARENT TABLES:-  For every table created in Data dictionary (DDIC) there will be table created in database with same name, same no of fields, fields having same names and the order of the fields will be same. That means for every same replica of table or mirror image will be created in Data base. That means it is having one to one relation. By default every table created will be Transparent Table.

CLUSTERED TABLES:- Many tables created in DDIC are stored in single table in data base called table cluster. That means it is having many to one relation. All the tables present in table cluster will have primary key in common.

POOLED TABLES:- In  case also many tables created in DDIC are stored in single table in database called table pool. Hence it also  having many to one relation. Here the tables present in table pool many have primary key in common.

EVENTS IN MODULE POOL PROGRAM IN SAP ABAP.

EVENTS IN MODULE POOL PROGRAM IN SAP ABAP. 

Process before output (PBO)

Process after input (PAI)

Process on value-request (POV)

Process on help-request (POH)

PROCESS BEFORE OUTPUT:-  This event is triggered before the screen is displayed. This event is used to assign some default values to screen fields. With those values the field will be displayed.

PROCESS AFTER INPUT:-  This event is triggered after giving input to the screen fields. This is used to handle user action actions on the screen.

PROCESS ON VALUE-REQUEST:- This is used to give F4 help to screen fields.

PROCESS ON HELP-REQUEST:- This is used to give F1 help to screen fields.

The in the module pool program should be written between module and endmodule.

AT EXIT-COMMAND:- It is used to go to the leave the screen or process some logic even though some of the mandatory fields of a screen not filled.

SY-UCOMM:- It is a system variable used to catch the  function code that is triggered for user actions on the screen.

OK_CODE:- It is used as substitute for sy-ucomm.

Pre-requisites for using Control break statements

Pre-requisites for using Control break statements in sap. 

Pre-requisites for using Control break statements Control break statements should be used in side the loop but on change of can be used outside the loop. Before using the control break statement the internal table should be sorted by the field on which control break statement is going to be used.

 

AT FIRST:- This is triggered at the first record of the internal table. This is triggered only once. It is usually used to write the heading to columns while displaying the records of internal table.

AT LAST:- This is also triggered only once at the last record of the internal table. This is used to find out grand totals of numeric values.

AT NEW <FIELD>:- This is triggered at the starting of every new record based on a particular field. It is used to calculate sub totals.

AT END OF <FIELD>:- This is triggered at the end of every new record based on a particular field. It is also used to find out sub totals.
