Flat File load best practice

Hi,
I'm looking for a Flat File best practice for data loading.
The need is to load a flat fle data into BI 7. The flat file structure has been standardized, but contains 4 slightly different flavors of data. Thus, some fields may be empty while others are mandatory. The idea is to have separate cubes at the end of the data flow.
Onto the loading of said file:
Is it best to load all data flavors into 1 PSA and then separate into 4 specific DSOs based on data type?
Or should data be separated into separate file loads as early as PSA? So, have 4 DSources/PSAs and have separate flows from there-on up to cube?
I guess pros/cons may come down to where the maintenance falls: separate files vs separate PSA/DSOs...??
Appreciate any suggestions/advice.
Thanks,
Gregg

I'm not sure if there is any best practise for this scenario (Or may be there is one). As this is more data related to a specific customer needs. But if I were you, I would handle one file into PSA and source the data according to its respective ODS. As that would give me more flexibility within BI to manipulate the data as needed without having to involve business for 4 different files (chances are that they will get them wrong - splitting the files). So in case of any issue, your trouble shooting would start from PSA rather than going thru the file (very painful and frustating) to see which records in the file screwed up the report. I'm more comfortable handling BI objects rather than data files - coz you know where exactly you have look.

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.

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.

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.

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 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...

FDM file format best practice

All, We are beginning to implement an Oracle GL and I have been asked to provide input as to the file format provided from the ledger to process through FDM (I know, processing directly into HFM is out..at least for now..).
Is there a "Best Practice" for file formats to load through FDM into HFM. I'm really looking for efficiency (fastest to load, easiest to maintain, etc..)
Yes, we will have to use maps in FDM, so that is part of the consideration.
Questions: Fix or delimited, concatenate fields or not, security, minimize the use of scripts, Is it better to have the GL consolidate etc...?
Thoughts appreciated
Edited by: Wtrdev on Mar 14, 2013 10:02 AM

If possible a Comma or Semi-Colon Delimited File would be easy to maintain and easy to load.
The less use of scripting on the file, the better import performance.

Essbase unix file system best practice

Is there such thing in essbase as storing files in different file system to avoid i/o contention? Like for example in Oracle, it is best practice to store index files and data files indifferent location to avoid i/o contention. If everything in essbase server is stored under one file directory structure as it is now, then the unix team is afraid that there may run into performance issue. Can you please share your thought?
Thanks

In an environment with many users (200+) or those with planning apps where users can run large long-running rules I would recommend you separate the application on separate volume groups if possible, each volume group having multiple spindles available.
The alternative to planning for load up front would be to analyze the load during peak times -- although I've had mixed results in getting the server/disk SME's to assist in these kind of efforts.
Some more advanced things to worry about is on journaling filesystems where they share a common cache for all disks within a VG.

One Time Flat File load in a Cube that extracts from ECC

Hi,
I have a cube that is already extracting data from ECC on a daily basis. I am asked to load some historical data into the cube from their legacy system. My question is, how do i prepare that file from the legacy system to match the fields in the Cube? What are the technicalities that i need to look at?
For Example:
0MATERIAL in the Cube: Material Number in the Flat File
ZAMOUNT in the Cube: Cost of Product in the Flat File
How do I arrange to match these?
Thanks

Hi
Create DS and enter the required objects
Preview the Data
Create Transformations (Map DS fields to Targets Objects - direct assignemnt)
Create Infopack and extract data upto PSA
Create DTP and run - it will extract data from PSA to Target
No of Heade rows to be ignored : 1
File type : CSV
Data seperator : ;
Escape Sign: "

Error while creating process chain for flat file loading

Hi All,
I had Created a process Chain to load Transactiion data(Full load) form flat file which is in my computer.
start>Load>DTP>DeleteIndex>DTP loading CUBE--> Create Index
but the system is throwing an error as "An upload from the client workstation in the background is not possible."
I dont know why this error is coming?
Can some one help me
Regards
Mamta

Hi Mamta,
Basically if you want to load the DS through FF using process chain, the FF has to be placed in Application server. We cant load the FF when it is located in the client local workstation(FF On your PC).
So better you remove the Infopackage step from the PC. Load the IP manually. Once it is completed you can start the process chain with the following steps:
start>DTP>DeleteIndex>DTP loading CUBE> Create Index
Hope it is clear & helpful!

Thanks,
Suryam.

Hi All,
Thank you.
Khaja,
I got the data upto PSA is fine and I am able to load the data in to DSO but I got the error while activating DSO
Ashok,
I loaded master data before loading Transactional data.May be it problem with file format.How can I check these format issues.
Brian,
We are using Transformation in BI7.0.I tried put conversion in DataSource level i.e Alpha for the field.But still I am getting same error.
Pls advice me on the above issue.

Regarding flat file load to DSO...

Hi Experts,
I am trying to load transaction data from flat file to DSO in BI7.0 that comprises two characteristics and one keyfigure. The characteristics type is char and keyfigure's type is int. Till PSA, data is fine. In transformation, I have just done one-to-one mapping with source field and target field, but while executing DTP, the error popped up as follows,
Data package 1:Errors during processing
Extraction completed, processing termination
Please help. I tried various combinations, but not able to schedule. Valuable answers would be awarded remarkably.
Thanks,

Hi there...
Here are some ideas to Ur problem
Assuming that u defined info objects correctly, length and types... and u mapped transformations correctly
And ur data in flat file is absolutely correct...
Of course very common but suggestible is plz check the data lengths in flat file and defined length of the info object.. If yes
Come to Data source and check the settings for the flat file ,separater and escape sign and rows to ignored..and check the data preview...
Plz compare the data in PSA and Flat file... plz do this very carefully... If yes...
Go to data source and at the FIELDS tab and check whether u assigned info objects correctly...if yes...
Check the conversion routines in the same screen of the tab FIELDS.. if for key figure u see PER16.. Remove it and try to load to PSA and do load the cube..
Hope this can give u an idea...
Regrds...KP
