Flat FIle loading - 80Million Records at atime

Hi Folks
Our Requirement is to load a flat file with 80 million records at one time.Now,what could be the best way to load the data in this case?
We have to report based on Region : (East,West,North n South)
i have two ideas n please correct me if i am wrong :
1. Create Infopackages for each region and load the flatfile to one Infocube
2. Create four infocubes one for each region and build a multiprovider on it for reporting
Please suggest me if there s any other way to go for
Thanks
Sriman

Hi,
Dividing into 4 will also be loading approx. 20 miliion records each...is there any other char value by which you can decide the Infopackage selections?
You can load through a process chain but in this case the file needs to be placed on your App Server.
Hope this helps...

Issue with flat file loading timing out

Hello
I have a scenario, where I am loading a flat file with 65k records into a cube. The problem is, in the loading process, I have to look up the 0Material table which has a million records.
I do have an internal table in the program, where I select a subset of the Material table ie around 20k to 30k records. But my extraction process takes more than 1 1/2 hrs and is failing (timed out).
How can i address this issue? I tried building indexes on the Material table and its not helping.
Thanks,
Srinivas.

Unfortunately, this is BW 3.5, so there is no END routine option here. And I tried both .csv and notepad file methods, and both are creating problems for us.
This is the total code, do you guyz see any potential issues:
Start Routine (main code)
refresh i_oldmats.
refresh ZI_MATL.
data: wa_datapak type transfer_structure.
loop at datapak into wa_datapak. (** I collect all the old material numbers from my flat file into an internal table i_oldmats**)
   i_oldmats-/BIC/ZZOLDMATL = wa_datapak-/BIC/ZZOLDMATL.
   collect i_oldmats.
endloop.
sort i_oldmats.
SELECT /BIC/ZZOLDMATL MATERIAL (** ZI_MATL only has recs. where old materials exist, this gets about 300k records out of 1M**)
         FROM /BI0/PMATERIAL
         INTO ZI_MATL FOR ALL
         ENTRIES in i_oldmats WHERE
          /BIC/ZZOLDMATL = i_oldmats-/BIC/ZZOLDMATL .
            collect    ZI_MATL.
Endselect.
Sort ZI_MATL.
Transfer rule routine (main code)
IF TRAN_STRUCTURE-MATERIAL = 'NA'.
    READ TABLE ZI_MATL INTO ZW_MATL
    WITH KEY /BIC/ZZOLDMATL = TRAN_STRUCTURE-/BIC/ZZOLDMATL
    BINARY SEARCH.
    IF SY-SUBRC = 0.
      RESULT = ZW_MATL-MATERIAL.
    ENDIF.
ELSE.
    RESULT = TRAN_STRUCTURE-MATERIAL.
ENDIF.

Transformation not generating-Flat file loading

Hello guys, I hope you can help me with this little confusion I have on BI7 Flat file loading.
I got a File (CSV) on my workstation. I am trying to load Master Data. Here is the example of my file and issues:
Lets say, I have CSV file named "CarModel.CSV" on my PC.
This excel file has 10 Records and No atributes for this Field.
So the records should show like this and it is showing correctly in PSA level, DS level.
A
B
C
D
E
F
My goal is to load Flat file data to InfoObject (inserted in Infoprovider)
I created Source system, DS, all thats stuffs.
I am now on Display DS screen under Proposal Tab. I am putting 10 Records to show and hitting Load example data....it works fine by showing all 10 records. However in the bottom part of this screen, what should show as a Field ?In my case , First it was showing the First Record ("A")...i didnt think it was correct but i prceeded anyways. Transformation could not be generated.
I tried by deleting "1" from the field "No. of header rows to be ignored" and its the same result ..No transformations.. I mean i know its very simple to load this data but i am not sure what i am doing wrong..My question is:
1) What should show under Field/propasal tab in my case?am i supposed to create this Field?
2) Should the system to propse the field which is from my flat file header ?in my case i dont have any header..should i have include header in my csv file like "car model"? i am confused please give me some info thanks
dk

Hi,
In filed tab, u have to enter ur infoobject names in an order...and press enter it'll automatically give the description and its other factors...
i guess u shuld have some header in the sense eg: customer,cust ID like this..this only u have to enter as fields...in proposal tab...try that

Flat file load changes in key figures

Hello,
I have a weird issue when i try to load some data into a cube(Flat File) with 1900 records only 1668 records gets loaded into the cube and also when i try to validate it the numbers doesnt match.Can you guys suggest me if i am missing anything here.Do i have to double check anything.Please let me know.Any help greatly appreciated.
Thanks,
Vinay

nothing problem for your cube model.
there are some records with same charectertic values. you can validate it, calculate sum of 1 KF in cube and calculate sum of 1 KF colomn. you can compare both values.
both values should match.
assume...flat file data
customer amount
1000 10
1001 20
1002 30
1000 10.
cube will have
customer amount
1000 20
1001 20
1002 30
hope this helps.

Flat File with multiple record types (OWB 10.2.0.2)

Hi!
I`m using OWB 10.2.0.2 and I`m trying to load a flat file with multiple record types, using SQL LOADER.
In the flat file editor in the Record tab, I`ve set the type values and the corresponding record names like this:
Type Value Record Name
======== ===========
T TRAILER
0 DETAILS
1 DETAILS
2 DETAILS
When using this flat file in a mapping to load the data in a staging table, the generated code looks like this:
INTO TABLE TRAILER
TRUNCATE
REENABLE DISABLED_CONSTRAINTS
WHEN (1:1) = 'T'
INTO TABLE DETAILS
APPEND
REENABLE DISABLED_CONSTRAINTS
WHEN (1:1) = '0,1,2'
The above clause (WHEN (1:1) = '0,1,2') is wrong as I expect one "INTO TABLE..." clause for each record type.
Could this be a bug or am I doing something wrong?
Thanks a lot for your help,
Yorgos

We`re using two target tables, one for the trailer record and the other for the details records.
We are facing this problem from the moment we upgraded from OWB 10.1 to OWB 10.2.0.2, so we think it must be something with the way the sql loader code is generated in the new version.
As our data sources are mainly flat files coming from mainframes, this is a huge problem for us. We even asked an expert in DW from Oracle to help us on this, but still haven`t found a solution.
Is there any workaround for this or should we forget sql loader and go with an external tables + custom PL/SQL code solution?
Your help is greatly appreciated Jean-Pierre.

Yorgos

Unit Code, Commercial Code - Flat File loading vs BPS Loading

Hi SDN Community,
Recently, we have moved our flat file loading to be performed by BPS interfaces.
During flat file loads, the Commercial code of all units of measures, are verified.
eg.DAY
But when loaded by BPS, the UNIT code is verified.
eg. TAG.
In the display of the BPS upload, it displays DAY which is the commercial code.
The only thing, is the customer is forced to use TAG in the BPS upload files.
They wish to create another record in the transaction
CUNI to be
Unit code = DAY
Commercial code = DAY.
However, i have found that we cannot allocate the same commercial code to another unit code.
Is this a design constraint, or a process error that i am doing.
Thank you.
Simon

Dear customer,
As i do not fully understand how this works, but the base table T006A
has 2 entries, 1 for english, 1 for German, should it not be that the
English EN entry field be working rather that the German DE, hence DAY
should be used? Can you please confirm my understanding on this?
>>> If you check my attachment "SE16.xls", you can see that it's for
language >>English<<, and the internal format is TAG while the external
format is DAY.
- Are there any plans to modify the BPS functionality in newer SAP BW
versions to allow the customer to indicate the same UOM as per flat
file laods? Or is an upgraded Support Pack that allows this?
- If not, would it be possible to make any customer enhancements to
allow this to take place depending on customer requirements.
>>> There is no plan at this moment to change this BPS functionality
in newer SAP BW versions or support packages.
We really recommend you to use internal format TAG in the upload file
in BPS which I think should be acceptable and feasible to you. All
other ways trying to use external format is risky and we cannot assure
you that it will work well as it's not SAP standard function. (I think
it's not worth the risk as the standard function which requires
internal format should not be too unacceptable)
Thanks for your understanding.
I also don't think my BC-SRV-ASF-UOM colleague would be able to help
you a lot regarding this.

Problem in flat file loading(bulk data)

Hi,
I am populating a flat file with 3lac records. I am getting error due to buffer space problem.
"Error during target file write "
around 2 lac records are getting inserted after that the above error is coming..
Now temporarily I am populating 1.5 lac and 1.5 lac in two times.
Could anyone please tell me how to solve this issue .
Thanks in Advance.

I am using owb 10.2 version.
In the map source is a Oracle table, Target is a flat file.
Source table contains 3lac records.
I executed the map. During execution it is throwing the following error .
"Error during target file write "
But it has inserted 2lac records in the target file.

Best practise around handling time dependency for flat file loads

Hi folks,
This is a fairly common situation - handling time dependency for flat file loads. Please can anyone share their experience around handling this. One common approach is to handle the time validity changes within the flat file where it is easily changeable by the user but then again is prone to input errors by the user. Another would be to handle this via a DSO. Possibly, also have this data entered directly in BI using IP planning layouts. There is a IP planning function that allows for loading flat file data but then again, it only works without the time dependency factor.
It would be great to hear thoughts or if anyone can point to a best practise document for such a scenario.
Thanks.

Urgent: Flat file load issue

Hi Guru's,
Doing loading in data target ODS via flat file, problem is that flat files shows date field values correct of 8 characters but when we do preview it shows 7 characters and loading is not going through.
Anyone knows where the problem is why in the preview screen it shows 7 characters of date when flat file has 8 characters.
Thanks
MK

Hi Bhanu,
How do i check if conversion is specified or not and another thing is it is not just one field we have 6 date fields and all of them are showing 7 characters in PSA after loading where as flat file have 8 characters in all of the 6 date fields.
In PSA I checked the error message it shows 2 error messages:
First Error message:
The value '1# ' from field /BIC/ZACTDAYS is not convertible into the
DDIC data type QUAN of the InfoObject in data record 7 . The field
content could not be transferred into the communication structure
format.
em Response
The data to be loaded has a data error or field /BIC/ZACTDAYS in the
transfer structure is not mapped to a suitable InfoObject.
The conversion of the transfer structure to the communication structure
was terminated. The processing of data records with errors was continued
in accordance with the settings in error handling for the InfoPackage
(tab page: Update Parameters).
Check the data conformity of your data source in the source system.
On the 'Assignment IOBJ - Field' tab page in the transfer rules, check
the InfoObject-field assignment for transfer-structure field
/BIC/ZACTDAYS .
If the data was temporarily saved in the PSA, you can also check the
received data for consistency in the PSA.
If the data is available and is correct in the source system and in the
PSA, you can activate debugging in the transfer rules by using update
simulation on the Detail   tab page in the monitor. This enables you to
perform an error analysis for the transfer rules. You need experience of
ABAP to do this.
2nd Error Message:
Diagnosis
The transfer program attempted to execute an invalid arithmetic
    operation.
System Response
Processing was terminated, and indicated as incorrect. You can carry out
    the update again any time you choose.
Procedure
1. Check that the data is accurate.
-   In particular, check that the data types, and lengths of the
            transferred data, agree with the definitions of the InfoSource,
            and that fixed values and routines defined in the transfer rules
-   The error may have arisen because you didn't specify the
         existing headers.
2. If necessary, correct the data error and start processing again.
Thanks

Flat file load - Cube

Hi Experts,
I have loaded data to cube through Flat file in BI7. The request is in green at manage option and reportable but the transferred and added records are 0. Please help me out.
Regards,
Ravi

Did you run delta dtp from PSA to Cube ? which was already loaded I guess check in cube
If the request from PSA already loaded to cube and next time when you run delta dtp again it will fetch 0/0 records...
Are you sure you have loaded PSA with new request which was not yet loaded to cube?

Flat File Load Issue - Cannot convert character sets for one or more charac

We have recently upgraded our production BW system to SPS 17 (BW SP19)
and we have issues loading flat files (contain Chinese, Japanese and
Korean characters) which worked fine before the upgrade. The Asian
languages appear as invalid characters (garbled) as we can see in PSA. The Character Set
Settings was previously set as Default Setting and it worked fine until
the upgrade abd we referred to note 1130965 and with the code page 1100
the load went through (without the Cannot convert character sets for one or more characters error) however the Asian language characters will appear
as invalid characters. We tried all the code pages suggested in the note e.g.
4102, 4103 etc on the info packages but it did not work. Note that the
flat files are encoded in UTF-8.

I checked lower case option for all IO
When i checked the PSA failed log no of records processed is "0 of 0" my question is with out processing single record system is througing this error message.
When i use same file loading from local workstation no error message
I am thinking when I FTP the file from AS/400 to BI Application Server(Linex) some invalid characters are adding but how can we track that invalid char?
Gurus please share your thoughts on this I will assign full points.
Thanks,
