Hi,
*Just declare it in string data type with large value in bracket like this,
data : loc_var(250) type string,
*Make sure that you last value should be saved in this local variable(loc_var) and append this variable in to a internal table and use that internal table for uploading data in the transaction.
Thanks,
Sakthi C
That answers my question.
Thank u all once again for replying,
regards,

Question in BDC session method.

Hi guys,
I am trying to upload BOM using BDC session method.
While doing this, i have learnt the steps by heart. But i do not understrand the logic behind the steps. For example, why do we include this statement
Data: IT-BDC like BDCDATA occurs 0 with headerline.
What if we don't include this statement?

Hello Dhirendra,
Thanks for immediate reply. I want to understand BDC method conceptually. What exactly happens by performing each step.
I am putting up the BDC i made. I copied some of the code from here and there. It works fine but i don't understand the purpose of BDCDATA,
call transaction 'cs01'
and form bdc_dynpro and form bdc_field.
I am quite new to ABAP. Please don't mind if i ask dumb questions.
I am unable to understand how control flows through the code logic.

Questions on BDC program statements.....

Hi,
Currently i am checking below BDC program for packing material use.
But there is a statement that i am not very clear what it is for...
    PERFORM bdc_field       USING 'BDC_CURSOR'

And if this is a BDC running in background, or a call transaction, then placing the cursor on a given field has no effect unless it is needed for navigation to the next screen.
When you record a BDC using SHDB there are a lot of statements like this that are added in but are not needed for the BDC to work.
Another example is the "BDC_SUBSCR" field name - this does not in most cases appear to have any effect on how the BDC is processed.
Also, the recording will include fields which have default values on the screen that you do not need to overwrite with the same value from the BDC.
I often delete these statements from the recording, taking care that I understand what the impact is. You can try commenting out the line and see what difference it makes to processing.
When using a BDC for updating a lot of records, having less of these types of lines in the BDCDATA table will speed performance a bit.

Question for BDC about tcode VK12

Hi, everyone, i encounter a problem when i use BDC to transfer data about vk12.
when i usd BDC to transfer value to the field F001,F002, F003 and F004-LOW then click run, the detail record are be chosed and displayed, then i must chose them and click delete. if there is only one record accord to the condition, it is easy to deal with it, but, if there are more than one record, what should i do the deal with the detail records, especially how to deal with it dynamicly acoording to the condition.
for example:
when i enter first condition through BDC .(see the first record)
ZPR0|X||RENT-L1-M03||100001||1000|00|01.01.2008|
the condition value are: zpro, x , rent-l1-m03, 100001,1000, 00 ,01.01.2008 and then i will find only detail record according to this condition, it like this:
RENT-L1-M03
2,000.12
sgd
1
ea
01.01.2008
31.12.9999
then flag this detail record and click delete.it is successful
when i enter second condition through BDC .(see the second record)
ZPR0
X
RENT-L1-M00
100021
1000
00
01.01.2008
the condition value are: zpro, x , rent-l1-m00, 100021,1000, 00 ,01.01.2008 and then i will find three detail records according to this condition, like this:
|RENT-L1-M00|2,000.12|sgd|1|ea|01.01.2008|31.12.9999
|RENT-L1-M00|2,000|sgd|1|ea|01.01.2008|31.12.9999
|RENT-L1-M00|1,000|sgd|1|ea|01.01.2008|31.12.9999
then if i use the same BDC record program to deal with this detail record, it is deal with only one detail record, so what should i do to deal with the others.(because all of them should be flaged and deleted)

Just check if you have a Select All button when you select the record you want to delete.

Interview Question in BDC

hi all,
i need to know the control commands available in BDC.

Hi Suresh
<b>BDCDATA structure might be asked very frequently.
BDC modes like A,E,N etc asked very frequently.

One interview question in BDC

there r 10,000 records in a flatfile and first record contains error, if i upload to the bdc pgm,and run in session method what will happen.

Hello Selva,
In case of session method, you create a session that is available in SM35. You can process the session thru SM35. In session log, all the records that have errors shows up as in error state and others are as processed/success status.
The session can be re-processed to clear the records in error state. On re-processing of the session system will only pick the records in error state and successful records are not touched.
Thatz the beauty of session method, tell me if you have more doubts

Question about BDC program

I wanna to write a program for creating profit center (KE51). Here are part of the codes:
form create_profit_center.
refresh bdctab.
perform fill_screen using:
    'SAPLRKPM' '0200' 'X' space space,
    space space space 'PRCT_V-PRCTR' 'TEST1',
    space space space 'BDC_OKCODE' '/0',
    'SAPLRKPM' '0298' 'X' space space,
    space space space 'PRCT_V-DATAB' '01.01.2005',
    space space space 'PRCT_V-DATBI' '31.12.9999',
    space space space 'PRCT_V-KTEXT' 'Test Profit Center 3',
    space space space 'PRCT_V-LTEXT' 'Test Profit Center 3',
    space space space 'PRCT_V-VERAK' 'ABC',
    space space space 'PRCT_V-KHINR' '1001',
    space space space 'BDC_OKCODE' 'PRCT_SCREEN_CC'.
    call transaction 'KE51' using bdctab mode 'A' update 'S'.
    if sy-subrc <> 0.
      write :/ 'Error when creating profit center.'.
    endif.
endform.
form fill_screen using program
                       dynpro
                       dynbegin
                       fnam
                       fval.
clear bdctab.
bdctab-program = program.
bdctab-dynpro = dynpro.
bdctab-dynbegin = dynbegin.
bdctab-fnam = fnam.
bdctab-fval = fval.
append bdctab.
endform.
When I execute the program in mode 'A' (view all the input screen), the program got stuck to the first screen. I can't see any fields (at least I expected the field 'PRCT_V-PRCTR is filled with the value 'Test1')being filled but only an error 'Make an entry in all required fields'.
Can anyone please help? Thanks!

Thanks for your reply.
I have tried to add
Data: V_kokrs like csks-kokrs value 'CA01'.
SET PARAMETER ID 'CIC' FIELD V_KOKRS.
OR
perform fill_screen using:
'SAPLSPO4' '0300' 'X' space space,
space space space 'SVALD-VALUE'<Controlling Area>,
space space space 'BDC_OKCODE' 'FURT'.
but it does not work. The error still exists.
I know that it is required to enter the controlling area before creating profit center. But when you have once saved the controlling area, it will no longer automatically prompt out when using t-code ke51 again. You need to go to the menu 'Extras -> set controlling area' if you wanna to set the controlling area again. So during recording, the starting screen is 'SAPLRKPM' '0200' instead of 'SAPLSPO4' '0300'. I just wonder in normal case you got stuck in a screen, your input value will be colored in red. But in my case, even I have set the value of profit center, the field is still blank.
I will now try to do it via BAPI. But I am still have interest in what's wrong with the BDC. Thanks!

QUESTION ON BDC

whats disadvantage of batch input session OVER call tranction method?
Note:Answer shuold be with respect to calltransaction method.

hi
good
Session method.
1) synchronous processing.
2) can tranfer large amount of data.
3) processing is slower.
4) error log is created
5) data is not updated until session is processed.
Call transaction.
1) asynchronous processing
2) can transfer small amount of data
3) processing is faster.
4) errors need to be handled explicitly
5) data is updated automatically
Batch Input (BI) programs still use the classical BDC approach but doesnt require an ABAP program to be written to format the BDCDATA. The user has to format the data using predefined structures and store it in a flat file. The BI program then reads this and invokes the transaction mentioned in the header record of the file.

BDC Questions

Hi
Can you give answers for these questions?
1)What are the transactions we should use in BDC? How do we use it?
2)How would you use BDC program to transfer material master record using MM01 transaction? Give me steps.
3)Could we use ME21N transaction, and XK01 transaction, either which one of the transaction, or could we use both the transactions for creating purchase information.
4)How can we use XD02 transaction to change the customer data for updating KNA1 table? Give the steps.
5)How the transaction ME21N is used for to upload the purchase order in BDC?
6)How many transaction we can used in BDC at a time?

Hi,
BDC:
Batch Data Communication (BDC) is the process of transferring data from one SAP System to another SAP system or from a non-SAP system to SAP System.
Features :
BDC is an automatic procedure.
This method is used to transfer large amount of data that is available in electronic medium.
BDC can be used primarily when installing the SAP system and when transferring data from a legacy system (external system).
BDC uses normal transaction codes to transfer data.
Types of BDC :
CLASSICAL BATCH INPUT (Session Method)
CALL TRANSACTION
BATCH INPUT METHOD:
This method is also called as CLASSICAL METHOD.
Features:
Asynchronous processing.
Synchronous Processing in database update.
Transfer data for more than one transaction.
Batch input processing log will be generated.
During processing, no transaction is started until the previous transaction has been written to the database.
CALL TRANSACTION METHOD :
This is another method to transfer data from the legacy system.
Features:
Synchronous processing. The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.
Updating the database can be either synchronous or asynchronous. The program specifies the update type.
Transfer data for a single transaction.
Transfers data for a sequence of dialog screens.
No batch input processing log is generated.

BDC Intervew Question.

Hai Gurs.
One intervew Question
In BDC requriment which one you going to choose to do
1) session method or
2) Call Tranaction method.
if you choose perticually -
that one mean why ?

Hi,
Depending on the requiremnet u need to go for the type of the method read below given breif discription about different methods:
To perform data migration from legacy database to new SAP database, BDCs are used. There are three methods in BDC as follows:
1. DIRECT INPUT METHOD
2. CALL TRANSACTION METHOD
3. SESSION METHOD
There are predefined tools used to perform data migration in SAP. They are:
1. RECORDING METHOD (SHDB)
2. LEGACY SYSTEM MIGRATION WORKBENCH (LSMW)
FUNCTION MODULES USED IN BDC:
1. UPLOAD
2. BDC_OPEN_GROUP
3. BDC_INSERT
4. BDC_CLOSE_GROUP
DIRECT INPUT METHOD:
This method is used to perform bulk data transfer from the flat file into the database table.
During data transfer, no manual intervention is required.
ERROR RECORDS:
Records already existing in the database table are called as Error Records. Such Error Records can be handled efficiently using CALL TRANSACTION statement.
ADVANTAGES OF DIRECT INPUT METHOD:
1. We can perform data migration for large number of records.
2. No manual intervention is required during data transfer.
3. Data migration is very fast using this method.
DISADVANTAGES:
1. Error Records cannot be modified during runtime.
CALL TRANSACTION METHOD:
The error records from the flat file can be handled using this method. Whenever SAP comes across error records, these are displayed in a user-defined screen.
CALL TRANSACTION <tcode> statement is used to call the user-defined screen to populate the error records.
3. BDC SESSION METHOD:
Function modules used in SESSION METHOD are:
1. BDC_OPEN_GROUP - This FM is used to create a session with flat file records in the Application Server. While creating session using this FM, we have to specify the CLIENT NUMBER, USERNAME and SESSION NAME.
2. BDC_INSERT - This FM is used to insert the internal table records into the session created in AS.
3. BDC_CLOSE_GROUP - This FM is used to save and activate the session to be processed later.
