BDC Releated Doubts

Dear All ,
I have few doubts regarding BDC
1) What are the parameters to be considered while selection the method of BDC ie session method or Call Transaction .
2) suppose I running BDC in background And i have 100 records.Assume my 41 , 47 record contains some junk data . what will happenn to other data after 47th record.

Hi Raghu,
You can decide based on the data volume that your BDC is processing. If data volume is high go for session else call transaction will do.The call transaction updates will be instantaneous where as session needs to be processed explictly after creation.
http://www.sappoint.com/abap/bdcconcept.pdf
you can do it both manually and by using program RSBDCSUB.

BDC/LSMW Doubt!

Hi Friends!
1) Could u pls tell me when to use BDC & When to use LSMW I am a technical Person i want to load data using LSMW Then when to do that? apart from doent need programming effort.
2) My Second Doubt is From LSMW, Suppose i am doing lsmw in development system can i transport the lSMW to Production & upload data to prod server just like BDC
or
I ve to do lSMW in production System to upload data in prod server
Since I am saving i am nor getting development class & transport req, that why.
Could u pls help me to solve my issue.
Thanks
Rahul.

BDC is for loading master data and LSMW for transaction data
BDC
BDC is basically for customized applications.
In bdc we have to give mapping concept explicitly.
It basically uses recording.
BDC is used by technical consultants , who do coding.
Coding can be done flexibly to customize applications.
LSMW
In lsmw mapping is take care by sap.
lsmw is basically for standard sap application.
LSMW offers different techniques for migrating data say : Direct input , Batch input recording , BAPI , IDOC
LSMW is basically designed for Functional consultants who do no coding .
Coding cannot be done flexibily as BDC.
Yes you can transport in LSMW! There is an import export option in extras of LSMW initial screen.

HI SOORYA,
1)SELECTION-SCREEN BEGIN OF BLOCK blk2 WITH FRAME TITLE text-002.
PARAMETERS: p_ifile LIKE dynpread-fieldname OBLIGATORY, " Input file
p_efile LIKE dynpread-fieldname OBLIGATORY. " Error file
SELECTION-SCREEN END OF BLOCK blk2.
It is a selection screen where u give filepath for the input file and also for the error file.
2)DATA : fm_file LIKE ibipparms-path .
its data transfer parameter for a local file to be uploaded or downloaded
3)DATA : v_file LIKE rlgrap-filename.

Doubt in BDC

I have a doubt in BDC,
They used a standard SAP program (RSBDCBTC_SUB and RFBIBL00) for upload the data for the transaction FBB1. they dont want the particular record .
They used a session method for upload the data.
I know only the session name. how I can delete the particular record.
Once processed the session.
Is it possible to delete the delete the record.
Help me regard this.

Priya,
here i can suggest u one thing
if u want to know the program r report related to that session
just go to sm35
select the session then go with analysis
then in the screen u will get the screens used in that particular program
when u double click on those screens control leads to that respected screen
in that if u go with system - > status u will get all the details of the program
when u double click on the program control leads into that program
then there u can find all the details related to tables and everything
i think it helps for u

Doubt in BDC (Creation of Production order)

Hi experts,
I have a doubt in my bdc, in my bdc i am going to create production order in CO01. its working properly but after entered the date i want to click operation overview and change one particular routing workcenter. But all the workcenter have the same field name of ARBPL, if anyone have a idea plz help its urgent. Point will be sure.
gowri

Dear Mr.Gowri Sankar,
As you have created a BDC for creating production order,
once after the order creation is over u can goto CO02 and change the work centre,routing details before release.
Please tell us when do u want to change the work centre & routing details?
If I'm wrong,please correct me.Also please share the concept of your BDC.

When execute this code it is just showing the empty screen of transaction vk13. It is not filling the condition type field with whatever value i am passing. When go in debugg mode i am not getting the logic again and again it is going to the first screen of vk13 and asking to enter the value whwn the statement CALL TRANSACTION is getting executed. It is clear to me.
My main doubt is we are clearing the internal table i_bdc_tbl before calling the transaction once we move the value to the specific field.I am not getting what they tried to do there.Simply moving one record to internal table and again clearing it then moving a next record and clearing it again before calling the transaction.
What we are trying to do by this?Can any one explain me.
Please help me out in understanding this.

Beginner ABAPer asking Doubts in BDC

Hi Guyz,
I am a beginner in ABAP. Here i am sending some doubts on BDC . Any Kind of help will be highly Appreciated.
Thanks,
SAM
1>How do we handle all the scrolling funcions(page ups, page downs atc), and values entered into table controls in BDC ?
2> How do you take care of screen resolution in BDC?

1) page up and page down ... i donno the actual procedure but this is one of the method...
i hope this answers both of ur questions...
After encountering the screen, say u need to select a field in a table. One of the methods is to press Control F on that screen then enter the field name which u want.. and press enter.. then that field will be the first field in the screen resolution ....
just try this for a normal table like spfli... after going to the table display in SE11 press control F or the Binoculars icon.. then u will get a small window u just type in the name of the field u want.. and press enter .. see what happens,
suppose ..
have opened this spfli in se11 transaction and in display mode..
Now 'PERIOD' is the field which is not there in the resolution..
so i have opened the find option ,provided the field name PERIOD in the field of search window.
then pressed enter. Now i will get the same screen( spfli display screen ) with period as the first field in that resolution .. Now i can do whatever is i want with this field.. here i have double clicked on the domain of the field PERIOD.
so u analyse this code....
*spfli display screen..
perform bdc_dynpro using 'SAPLSD41' '2200'. ( * spfli display screen , u can use ur screen number here )
perform bdc_field using 'BDC_OKCODE'
'=FIND'. (* To open the find window )
perform bdc_dynpro using 'SAPLSD41' '0114'. ( * This is the find window )
perform bdc_field using 'BDC_CURSOR'
'RSDXX-FINDSTR'.
perform bdc_field using 'BDC_OKCODE'
'=CANC'. (* OK_CODE for enter )
perform bdc_field using 'RSDXX-FINDSTR'
'PERIOD'. ( * Here i am giving the field name which i want to search or which is not there in the resolution or u can give a vaiable name which contains the value <FIELD NAME> ).
( Now i got the spfli display screen with period as the first field in the screen resolution )
perform bdc_dynpro using 'SAPLSD41' '2200'. (*The previous spfli display screen )
perform bdc_field using 'BDC_OKCODE'
'=WB_SELECT_OBJECT'. (* OK_CODE to double click on the domain of the field PERIOD )
perform bdc_field using 'BDC_CURSOR'
'DD03D-ROLLNAME(01)'.

Doubt in uploading purchase order data using BDC

Hi friends,
how to upload purchase order data.
1) In both BDC and BAPI which one is preferable?
2) for suppose if it is through BDC, how to use? what are the transactions that we can use(SHDB, ME21N,ME21)?
3) To execute the job in background, is it possible for both call transaction and session method.
Thanks in advance
Sreenivas k

It really depends on the number of records you have. Still for a set of 5,000 records my answer to your questions will be:
1) In both BDC and BAPI which one is preferable? - Go with BDC
2) for suppose if it is through BDC, how to use? what are the transactions that we can use(SHDB, ME21N,ME21)? - Yes, its SHDB for recording, SE38 for abap program and ME21 for PO. Avoid SAP Enjoy transactions for recording as you may end up having problems wiht it.
3) To execute the job in background, is it possible for both call transaction and session method. - If you use call transaction method then you have to schedule the job to run in background or simply run it through F9 instead of F8. In case of session method you can chose to process the session in background. However I would suggest you go with BDC Session method for this.

Doubt in bdc and ale reg

using we can transfer the data from one system and another system. in ale also we can do same thing. what is the need of using ale

BDC is used in scenarios where a company decides to do away with an existing ERP system and choses to use a SAP R/3 system in its place(Like from Oracle to SAP, or from any legacy system to SAP).
In the process, the company wil store all the legacy data in flat files before discarding the original system.
The flat file data, will have to be uploaded into the R/3 System again. It such cases BDCs/ Batch Iput programs are used.
ALEs are used in a totally different scenario.
If the company is using two loosely coupled sap systems, and the same data is to be maintained in both the systems, then you will use ALE concept.
It is like latching them together and changes made to one system are automatically refelected in the other system as well.

Ravi

Doubt in BDC ( Material master)

Hi frnds,
I am creating BDC for material master.In that BDC if i load the data in 'A' mode its work properly. In 'E' Mode in the last page its asking every time for Save, In 'N' Mode its not upload how to do this.
This is my code :
perform bdc_dynpro      using 'SAPLSPO1' '0300'.
perform bdc_field       using 'BDC_OKCODE'
                              '=YES'.
***********CALL TRANSACTION************************
CALL TRANSACTION 'MM01' USING bdcdata MODE 'E'
         UPDATE 'A'
        MESSAGES INTO it_bdcmsg.
Thanks,
Gowri.

Hi
May be in 'A' mode you are manually hitting the SAVE and saving
The function code/OK code for SAVE is 'BU' like
    PERFORM bdc_field       USING 'BDC_OKCODE'
                                  '=BU'.
so you have to write this in the last, then it won't ask in E and N modes
may be this is missing in the program see and correct.

Doubt in BDC direct input method

Hi experts
I dont know how to upload data in SAP data base by using BDC direct input coding method. Can u people explain this with coding?
Thanks in advance.
Regards
Antony

Hi,
DI is used when u r going upload large amount of data for single application.
Better example where direct input method will be used is... uploading the data for material master.....it includes lot of views so its very much difficult to capture all the views and record the tcode and map the data in such conditions its better to go with DI methods
advantages:
in session method or CT method while uploading the data u do the validation by fallowing the screen sequence and field sequence where as in DI validations can be done set of code so this make the process very fast so its advantageous to upload large amout of data.
you always use the standard sap provided program for this.
Here in DI method very important thing is structure of flat file... so to know the structure first of all you have to download the data for one record into the internal table with the use of the same program then with the use of that structure u have to desing the flat file and upload the data.
Re: re: direct input method

Simple doubt in BDC Call Transaction Method

Hi Friends,
When i try to call vk13 transaction and pass the screen field values for the second screen and execute it it is displaying properly.But when i try to pass the different value in the bcddata internal table it is changing properly but in the screen it not updating that value.Alawly the screen fields are taking the values passed the first time.But in the internal table which we are oassing to the calltransaction it is changing correctly but not in the corresponding screen fields. Why it is happening so. Can any one help me out of this problem.
Thanks in Advance.

I am not passing through the selection screen . It is like iteractive report. when i select the particular line in the list output then the screen fields should take the values from that selected line. First time when i select the line it is taking properly.
But next time when i select the line the content of the i_bdc_tbl is changing correctly but when it enter in to the transaction it is not taking the values from the i_bdc_tbl. Simply it is displaying the screen fields with the old values. It is not updating the screen fields with the values from the i_bdc_tbl. Why the screen fields are not replaced with the value of i_bdc_tbl? Why it is not getting refreshed with the new values?
Just i am posting the bdc portion of my code here. So you can help me out on this.

Hi
Look out for the error in the flat file which you are uploading. I have seen this error and I found it in Flat file. its a conversion error.
Just copy few lines from the original file, make a new file and upload it. In this way, you will be able to say whether there is an error in file or in code.

Doubts in BDC

hi friends ,
i have some questions regarding BDC`s
1)What is the difference between asynchronous processing & updating???
2)how can we use programe defined function module in bdc?
3)purpose of leave-to-transaction ? where it is used ?
4)when & how is direct input used?
regards
Rishi

Hi Rushikesh,
Here it is answers for oyu....
1)What is the difference between asynchronous processing & updating???
sol: Asynchronous process means first when ever data ispopulsting from the file it is processing the data means dealing out with the data nothing but check the all the data at a time. Asynchronous updating means update all the data at a time means controller doesn't wait for confirmation from the DB.
2)how can we use programe defined function module in bdc?
Sol: i think your asking about BDC-OPEN_GROUP, BDC_INSERT,BDC_Close.
If it is then first upload the data from file to internatl table and then data populated to DB through t-code by using bdcdata strucutre.
3)purpose of leave-to-transaction ? where it is used ?
Sol: Suppose your doing the at selection screen validation then we have ti use ths statement like
IF P_BUKRS IS INITIAL.
MESSAGE E(001) WITH 'XXXXXXXXXXXXXXXXXX'
LEAVE TO TRANSACTION ZVAL.
ENDIF.
4)when & how is direct input used?
Sol: Suppose we need ti uplaod the huge (nearly 1 or 2lakksh) records at a time then we can go for direct input method. This means directly hit to DB. First data can be populated to itab then by submitting two standard programs we can uplaod the data to DB.But problem is direct input have restart mechanism means suppose if you will ge error at 99999 record then we have to start agign the process.
Hope this helps you, reply for queries, Shall post you the updates.
