Regarding OOABAP

Hi
 I was created 1 class and in attributes I was given:
AI_DEFAULTS type YFIIF_EFUND_INPUT.
The Problem is while executing the report which uses this class, I am getting the error message that :
The following syntax error was found in the program
ZCL_FI_EFUND_LINE_MAPPER======CP :
""AI_DEFAULTS" has already been declared."
Can u please guide me where i was wrong.
Points are assured for Correct answers.
Regards,
Sree

Hello Sree
Apparently the attribute has been declared already. The class builder should not allow you to define duplicate attributes having the same name.
If you do not see where the first definition of AI_DEFAULTS is simply use the following approach:
1. Rename your second implementation, e.g. _AI_DEFAULTS.
2. Use the AI_DEFAULTS attribute in one of your method
3. Double-click on AI_DEFAULTS within your method -> should jump to the attribute definition

Uwe

hi ,
if u r chosing a single database table ,u will create a node name and its attribute in component controller or in view controller.example mara as node name and its attribute as matnr ersda and ernam.then right clicking on the UI element click create binding and select ur mode of display by selecting text view or dropdownbyindex.but in dynamic case, at runtime user will give any table name and any filter condition of selecting its field .so it is impossible to create 88000 table as node and select all fields. so now give child node name as 'tablename' with type string .
in component controller it has one parent node by default.if we create a new node it comes as child of patent node 'context'.
class cl_wd_dynamic_tool contain 4 methods in that method create_nodeinfo_from_struct has all importing parameter
1. give the reference parent node name which is stored in a varible rootnode_info.
(rootnode_info = wd_context->get_node_info( ). if u go to attribute column, u can found 3 interfaces with respective data refernces like wd_this,wd_context. if u dblclick if_wd_context_node u can find all info regarding the name of context, and any other newly created parameters.)
2.give structure name or table name which is is given at runtime.
3. for accepting many fields or with only one field.
in abap oops dynamic condition is attained by 2 ways 1. data reference and 2.field symbols.
data reference alias name is "address of".
field symbol alias name is "value at".(place holder)
DATA: stru_tab TYPE REF TO data.
this means u r creating a variable stru_tab which is having a properties of data.
assume "data" is a type or class , .here only u declare only variable ,it has no content till the statement create data.(memory space will allocate only after the execution of create data.)
FIELD-SYMBOLS:
<tab> TYPE table.
u can declare a field symbol with generic type "any " keyword or "table" keyword.
dynamic means u should mention within parenthesis (table name).
conventiontional way of declaring internal table is
data: <internal table name > type table of <table name>.
here u dont know the type table u r going to pass.
but definetly ,it contain data, so declare stru_tab as data .
DATA: stru_tab TYPE REF TO data.
in this step only variable name name is create not space.
CREATE DATA stru_tab TYPE TABLE OF (tablename).
in this step space is create for variable but only internal table name is declared.but no space
ASSIGN stru_tab->* TO <tab>.
internal table is of table format .so u declared field symbol as table.
stru_tab is address of data
<tab> is value at table.
then select query

Hello Raj
Actually all the code is described in PBO module, so you need to invoke this module in PBO when defining the screen.
For example, access transaction SE51, start in Change mode and inser line
 MODULE PBO.
Then activate the object

Regarding "Friend Function" in Object oriented Abap.

Hi! Every Body,
I need to know about this friend function in ooabap.
1. Clear Definition.
2. i need program too.
3. What is the use Of friend function?
4. wht is the difference from java and ooabap using this function.
if any body replies for my query , i really thank full to u.
regards,
M.swapna.
[email protected]

Hi Swapna,
Usually private components of a class can be accessed by methods of that class only..Sometimes, it is necessary for two classes to work so close to each other that one class needs to access the private attributes of the other.
In that case, you can make the former class, a friend of the latter class.
Suppose class A is made as a friend of class B.
Then A and its subclasses can access the private or protected components of the class B.
But they cannot access the private or protected components of subclasses of class B.
You can refer this link for more help.

OOABAP Report

Are there any GOOD standard programs / REPORTS to refer for OOABAP done already in SAP ?
Rgds,
Ö

Hi
ABAP Objects is a new concept in R/3 Release 4.0. The term has two meanings. On the one hand, it stands for the entire ABAP runtime environment. On the other hand, it represents the object-oriented extension of the ABAP language.
The following is a simple example shows the object-oriented aspect of function groups in the simple case of a counter.
Suppose we have a function group called COUNTER:
Create an abap program with this code :-
FUNCTION-POOL COUNTER.
DATA COUNT TYPE I.
FUNCTION SET_COUNTER.
Local Interface IMPORTING VALUE(SET_VALUE)
COUNT = SET_VALUE.
ENDFUNCTION.
FUNCTION INCREMENT_COUNTER.
ADD 1 TO COUNT.
ENDFUNCTION.
FUNCTION GET_COUNTER.
Local Interface: EXPORTING VALUE(GET_VALUE)
GET_VALUE = COUNT.
ENDFUNCTION.
End of program code
The function group has a global integer field COUNT, and three function modules,
- SET_COUNTER,
- INCREMENT_COUNTER, and
- GET_COUNTER, that work with the field.
Two of the function modules have input and output parameters. These form the data interface of the function group.
Any ABAP program can then work with this function group. For example:
REPORT ZABAPOO.
DATA NUMBER TYPE I VALUE 5.
CALL FUNCTION 'SET_COUNTER' EXPORTING SET_VALUE = NUMBER.
DO 3 TIMES.
CALL FUNCTION 'INCREMENT_COUNTER'.
ENDDO.
CALL FUNCTION 'GET_COUNTER' IMPORTING GET_VALUE = NUMBER.
WRITE: / 'After processing NUMBER is :- ', NUMBER.
End of program code
After this section of the program has been processed, the program variable NUMBER will have the value 8.
The program itself cannot access the COUNT field in the function group. Operations on this field are fully encapsulated in the function module. The program can only communicate with the function group by calling its function modules.

Issue regarding ABAP/4 language.

Dear All,
Can any body tell me that ABAP is fully object oriented language? Plz explain.
Regards,
Chandramohan.N

Hi,
ABAP is not Fully object oriented programming.
You can add normal procedural programming with Object oriented programming i.e. you can combine classical ABAP with ABAP Objects.
ABAP Objects is not entirely a new language, it is just an enhancement or added functionalities with in ABAP.

Difference between ooabap and java

eventhough both java and ooabap are oops languages there may be some difference between them as c++ and java in using the oops concepts or may be there is an advantage in using ooabap than java .
any one pls reply to the above asked question.

hi
OOPs ABAP uses Classes and Interfaces which uses Methods and events.
If you have Java skills it is advantage for you.
There are Local classes as well as Global Classes.
Local classes we can work in SE38 straight away.
But mostly it is better to use the Global classes.
Global Classes or Interfaces are to be created in SE24.
SAP already given some predefined classes and Interfaces.
This OOPS concepts very useful for writing BADI's also.
So first create a class in SE 24.
Define attributes, Methods for that class.
Define parameters for that Method.
You can define event handlers also to handle the messages.
After creation in each method write the code.
Methods are similar to ABAP PERFORM -FORM statements.
After the creation of CLass and methods come to SE38 and create the program.
In the program create a object type ref to that class and with the help of that Object call the methods of that Class and display the data.
Example:
REPORT sapmz_hf_alv_grid .
Type pool for icons - used in the toolbar
TYPE-POOLS: icon.
TABLES: zsflight.
To allow the declaration of o_event_receiver before the
lcl_event_receiver class is defined, decale it as deferred in the

Regarding sy-index and sy-tabix

Hi,
What is the major difference between sy-index and sy-tabix ,
can you give me one good example with code..
Regards,
Reddy.

Hi,
SY-TABIX - Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.
APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.
COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.
LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.
READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.
SEARCH FOR sets SY-TABIX to the index of the table line in which the search string is found.
SY_INDEX - In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.
sy-tabix is the tab index - the index of the record in the internal table you are accessing,
sy-index is the loop counter.
If you use a condition in LOOP the sy-index will go from 1 to n, but sy-tabix will refer to the line in the internal table.
Hope this helps u.
Thanks,
Ruthra
