Build daily Big flat file using SAP R/3 material master data

Hi all,
I must build an interface between SAP R/3 4.7 and an external application
Daily a flat file must be generated contaning Material data in full exchange mode
(volume 100 000 materials, <10 fields => ~ File of 30Mo)
No complex mapping, only format mapping (Ex : Price quantity...)
I don't know yet if I will use Idocs or BAPI to extract data. However, I'm sure I must use multiple inbound messages because of volume
After reading documentation, I consider the both following solutions to manage it :
1) A simple asynchronous interface with a file adapter in construction mode APPEND to build flat file progressively with arrival of SAP messages
=>
viable solution ?
Is there problem of concurrent access to file in such a solution ?
(idocs or bapi data will be processed ones following the others )
2) BPM Collecting and Bundling Messages - One Interface
(Unlimited Loop with Deadline trigger correspondint to time I must build flat file)
=>
Each SAP message is a small message but the outbound XML will represent a 30 Mo flat file => Is it a problem ??
Which solution do you advise ?
Is there another ?
Last question : (more general one)
In such scenario, I can't see XI-value added comparing a creation of flat file directly with R/3.
I will generate a big number of idocs, use a big part of XI memory ...
Can you give me your opinion about it ?
Thanks a lot
Best regards
Jean-Charles

Hi Jean-Charles,
>>>volume 100 000 materials, <10 fields => ~ File of 30Mo
You have a performance task...
>>>Is there problem of concurrent access to file in such a solution ?
No, the adapter framework has its own queueing, the message would be stored and executed later. If sequence is important, you can use EOIO as well.
>>>BPM Collecting and Bundling Messages - One Interface
BPM is not required in your case, you should avoid becoz of performance task. You can append at file adapter, no problem. Bundling and splitting is even possible at Integration Server without BPM.
>>>Each SAP message is a small message but the outbound XML will represent a 30 Mo flat file => Is it a problem ??
Avoid using BAD words
>>>Each SAP message is a small message but the outbound XML will represent a 30 Mo flat file => Is it a problem ??

Transferring MATERIAL MASTER DATA USING lsmw

I am using LSMW to transfer material master data from text file using direct input program RMDATIND. The problem is that the field WRKST in screen is of 48 characters while the batch data structure BMMH1 of field WRKST contains 14 characters. How can we transfer the full 48 characters in text file to THE FIELD BMMH1 IN DIRECT INPUT PROGRAM. Can we write any translation or routines . If yes, how is it possible. I can do the same using BDC but our client is already using the LSMW , only the new field WRKST for material has to be inserted. It is picking only 14 characters.

Hi Subrat ,
u can upload the data either ( Master /Transaction) data with the help of lsmw. for that all u need to do is go through the lsmw and do it. in that u can go Batch input recording/ BAPI/ IDOC any of that. here i am sending the LSMW Notes go through it and do the work.
once u create the LSMW project then u can ask the data from user or u can explain the user about the program and can run the flat file to upload the data.
if u require LSMW material Just send me blank mail from u. my mail id is [email protected]

How to seperate a big flat file

Hi Everyone,
I have a performance issue with loading a very big flat file. I have a 200 million flat file and I am trying to load it via Oracle Data Integrator to Sql server 2005. Oracle data integrator is trying to execute a bcp tool like below.
bcp CDWH_DW.dbo.Campaign_History_Outbound in "\\server\CDWH\FlatFile2Send \FILES\ailing_active.txt" -f"\\Server\Campaign\Campaign_Response_Outbound.fmt" -o"\\server\CDWH\FlatFile2Send\ \LOG\sony_mailing.log" -T -S"sqlserver " -C"RAW" -m 1
If I have a problem with data in this huge file it is very difficult to find what is wrong. So I am trying to find out a solution for this issue. Do you have a suggestion? I am thinking to separate this huge file a lot of small piece and loading them in a loop but I am thinking about how to separate this big file to a small piece.
Thank You for your Helps
Kind Regards
Caner Sahan

Hi Caner...
I believe that is possible.
There is any column, from text file, that can be used as PK?
What is the type of this text, delimited? positional?
Do you want this only for development or will keep it for production?

Idoc to flat file using Integration process does not show up at all

Hello All,
I created a scenario IDOC to Flat File using Integration Process and one without IntegrationProcess. I am able to execute the one without Integration Process easily.
However when I send the IDOC from SAP then the Integration Process scenario just does not work.
I Checked SXMB_MONI There is no entry for the Integration Process.I can see entry for other without Integration Process.
SXI_CACHE : I can see my Integration Process active
SWEQADM : I have activated the Event Queue and Background job
SWF_XI_ADM_BPE : ALL BPE is showing green status.
All syntax check on IP are fine.
There is no Basis Help for me so there could be some additional basis steps which need to be configured. Has anyone faced such an issue with Integration Process?
Regards
Prashanta

Hope this might help you. when u configure an IDoc as Sender with BPM this is how you proceed.
1. let us split the scenario into two.
a. Sender to BPM ( Integration Process).
b. BPM to Receiver.
2. First let us configure the first Sender to BPM.
a. Sender Agreement( Not required ).
b. Receiver Agreement( NOT Required).
c. Receiver Determination( Sender Service, Outbound Interface, Receiver Service(Integration Process).
d. Interface Determination( Inbound Interface(Sender Abstract Interface), Message Mapping(NOT Required if your using transformation stepin Integration Process)).
3. Now let us configure the Second BPM to Receiver.
a. Sender Agreement( NOT Required)
b. Receiver Agreement( Sender Service(Integration process), Receiver Abstarct Interface,Receiver service, Inbound Interface).
c. Receiver Determination( Sender Service(Integration Process), Receiver Abstarct Interface,Receiver Service).
d. Interface Determination( Inbound Interface, Message Mapping(NOT Required)).
So Finally we have One Receiver Agreement, Two Receiver Determinations, Two Interface Determinations.
Please let me know if you have any more queries.

How to import a logo from flat file to SAP in SMARTFORM.

how to import a logo from flat file to SAP in SMARTFORM. i need to know whether TIFF format is used and also the full steps.
Thanks,

Hi,
You can not directly use a logo from a file into a Smart form. First you will have to upload it to SAP. This has to be done only once. Once it is imported into SAP then you can use it in smart form. To import a logo to SAP, goto SE78. Open the tree under GRAPHICS. Select the file type and click on the Import (first button on the toolbar, just before delete button). Select the logo file and give it some appropriate name along with description. Select appropriate type of the image and click Continue. Your logo will be uploaded into SAP from a file. Now in your smartform, Create a Graphic Node, give the name of the logo along with other properties. In this way you can import a logo from a flat file into SAP and consequently in a smart form.
Reward points if the answer is helpful.

Time taken to upload a flat file in SAP BI

Hello Experts,
Want to know , about how much time it will generally take to upload a flat file in SAP BI having data volume near about 10 million .
OR what is standard time taken to upload the data from a flat file what ever be the size of the the flat file in terms of records ,
please provide me the detaild information regarding the time taken , plz clarify it , and thanks in advance

Hi,
there are some other points that you need to consider while trying to evaluate your question:
- how wide is your file/how many columns it has?
- what's the type of interface you using for flat file upload? is it: flat file loaded from user workstation? from application server? from web interface (like planning app)?
- how complex is login used to transform the data from flat file before data is saved in BW objects?
In general 10mil of records is not a problem is not a problem if you using upload from application server. If you using load from user workstation thsi can be an issue. Even less performant is load of that much data via web interface.

Delete data from a flat file using PL/SQL -- Please help.. urgent

Hi All,
We are writing data to a flat file using Text_IO.Put_Line command. We want to delete data / record from that file after data is written onto it.
Please let us know if this is possible.
Thanks in advance.
Vaishali

There's nothing in UTL_FILE to do this, so your options are either to write a Java stored procedure to do it or to use whatever mechanism the host operating system supports for editing files.
Alternatively, you could write a PL/SQL procedure to read each line in from the file and then write them out to a second file, discarding the line you don't want along the way.

/It fails as soon as it encounters the V_FLAG in the V_flat_file_line. The data in the table has nulls for the FLAG, and some -ve numbers for the ELC_COST,ADJ_ELC..but that should'nt cause any problems does it?

How to Create a Flat File using FTP/File Adapter

Can any body done workaround on creating the Flat file using FTP/File Adapter?.
I need to create a simple FlatFile either using of delimiter/Fixed length. using the above said adapters we can create XML file, i tried concatinating all the values into a single String and writing into a file, but it does not have proper structure
Can any body help me out on this..
Thanks
Ram

You can create a text schema while creating a File Adapter. If schema is specified for File Adapter, it takes care of converting XML into fixed length or delimited format.
Thanks,
