Logical File

What is the difference between logical file name and Physical file name when we are writing interfaces we will use this.
What is exact use of this ?
Can I have some information regarding this ...
Bye,
Muttu.

Hi Satya,
Hi,
As the name suggest, Logical file name is not the actual file name. It can be assiged dynamically (Transaction FILE).
Physical File name is the name of actual file.
To remove the hardcoding from the program, and also to achive functioanlities such as adding date and time stamp to the file name, Logical filenames are used.
Reward points if useful.
Thanks.

Using a Logical File definition in LSMW

Hi all,
is there any way that we can use a Logical File (defined in transaction FILE) as an application server file in the "specify files" step, instead of having to enter the physical path/file?
Thanks in advance,
Justin

Hello,
Check pages 46 and 47 of the following document :
[http://sapabap.iespana.es/manuales/pdf/lsmw.pdf|http://sapabap.iespana.es/manuales/pdf/lsmw.pdf]
You can only use a logical filename for subsequent programs (example direct input programs) not for the actual input file of your LSMW.

Open Hub: How-to doc "How to Extract data with Open Hub to a Logical File"

Hi all,
We are using open hub to download transaction files from infocubes to application server, and would like to have filename which is dynamic based period and year, i.e. period and year of the transaction data to be downloaded.
I understand we could use logical file for this purpose. However we are not sure how to have the period and year to be dynamically derived in filename.
I have read in sdn a number of posted messages on a similar topic and many have suggested a 'How-to' paper titled "How to Extract data with Open Hub to a Logical Filename". However i could not seem to be able to get document from the link given.
Just wonder if anyone has the correct or latest link to the document, or would appreciate if you could share the document with all in sdn if you have a copy.
Many thanks and best regards,
Victoria

Hi,
After creating open hub press F1 in Application server file name text box from the help window there u Click on Maintain 'Client independent file names and file paths' then u will be taken to the Implementation guide screen > click on Cross client maintanance of file name > create a logical file path by clicking on new entiries > after creating logical file path now go to Logical file name definition there give your Logical file , name , physical file (ur file name followed by month or year what ever is applicable (press f1 for more info)) , data format (ASC) , application area (BW) and logical path (choose from F4 selection which u have created first), now goto Assignment of physical path to logical path > give syntax group >physical path is the path u gave at logical file name definition.
however we have created a logical path file name to identify the file by sys date but ur requirement seems to be of dynamic date of tranaction data...may u can achieve this by creating a variable. U can see the help from F1 that would be of much help to u. All the above steps i have explained will help u create a dynamic logical file.
hope this helps u to some extent.

Hi Ram,
Try using FILE transaction code...
Follow these steps to create:::
Double click on Logical file Path Definition
Click on New Entries,
Give Logical file Path name as Z_LOGICAL PATH and save it
now choose this path and double click on Assignemt of Physical path to Logical path
double click on the OS name
Give some description and give some Physical path name from AL11 transaction and save it
Now Double click on Logical File Name Definition,
Click on New Entries,
Give some logical file name: Z_LOGICAL_FILENAME
Physical file: test
Data Format: BIN
Logical Path: Z_LOGICAL PATH

File system error: The record ID is incorrect. Physical file: . Logical file:

Hi,
I face this error message when I try to 'process update' a dimention, sometime it works but sometime it failed with the error below:
Description: File system error: The record ID is incorrect. Physical file: . Logical file: .
My environment: Window Server 2008 R2+SQL Server 2008 R2.
Note: this issue can be resolved by full cube process, but I can't to that every time if it failed, just want to know what happen at backend of SSAS, It block me neary 2 week without any finding, really appreciate that someone can help on this.
I have do some research with google, I think the root cause here is not TopCount function(It may be a problem with SQL Server2005), also not the size limitation of 4GB size of .astore file.(I check the size of my cube under 'Data\XXX.db\' folder, which only
have few MB size).
Thanks,
Tom

Hi Tom,
Here is a microsoft fix
FIX: "File system error" occurs when you try to run a process update operation on a dimension in Microsoft SQL Server 2008 Analysis Services and in Microsoft SQL Server 2008 R2 Analysis Services
In your acenario, in order to fix this issue, please apply the latest Cumulative update and Service Pack according to your SQL Server version. Besides, there are two workarounds in that fix, plese try it and check if it works or not.

Error while creating logical file using transaction FILE

Hello there,
I am facing an error while creating Logical File name definition using transaction FILE
This is the input which I'm trying to give
Logical file name: ZTEST
Name : ZTEST
Physical file : ZTEST_1<DATE><TIME>.csv
Data format: ASC
Application area: BW
Logical path:ZTEST_1_DATAOUT
when I tried to save it throws me an error like ASSIGN_SUBSTRING_NOT_ALLOWED
Please help.

Hi,
Please check the OSS Notes :
Note 792061 - SP Case Locator: Dump: ASSIGN to a substring isn't allowed.
SAP Note 1297989 - Short dump ASSIGN_SUBSTRING_NOT_ALLOWED
Hope this solves the problem.

LSMW - Logical File Path not pointing to Physical Path

Hi All,
I'm trying to upload some MIGO goods movement transactions through LSMW. I'm to step 7, specifying files, and am getting the error "No logical file path has been specified. I saw another thread which helped me, but I am still stuck after reading it.
Re: Error in Creation of Purchase Requisition through LSMW
I have gone into transaction FILE and created the logical file name MM_GOODS_MOVEMENT, and set the physical file as the .lsmw.conv converted data file as the above thread says. I also tried using the logical path LOCAL_TEMPORARY_FILES for the converted data, but I get the error telling me that the path does not point to a physical directory. I then tried creating my own file path, and setting the path to my desktop where the source file is, and the same error occurred.
Does anyone know why it is not recognizing the physical path maintained in the logical path?
Thanks,
J

Thanks for both replies,
I have full authorization across all transactions in the sandbox system I am working in, so that is not an issue. I filled the logical path field in the MM_GOODS_MOVEMENT logical file with LOCAL_TEMPORARY_FILES, as well as trying my own created file path, and I recieved the same error for each. Here is how the config is currently:
Logical File Path Definition: MM_GOODS_MOVEMENT
Syntax Group: WINDOWS NT
Physical path: C:\Documents and Settings\jchanski\Desktop\<FILENAME>
or,
Logical File Path Definition: LOCAL_TEMPORARY_FILES
Syntax Group: WINDOWS NT
Physical path: C:\temp\<FILENAME>
Logical File Name Definition: MM_GOODS_MOVEMENT
Physical file: MM_MM_MIGO_INVUPLOAD.lsmw.conv
Data format: ASC
Applicat.area: MM
Logical path: LOCAL_TEMPORARY_FILES or MM_GOODS_MOVEMENT
Do you see any error with this Brajvir? Thanks!

Creation of logical file while creating APD

Hello,
I am creating an APD in which Multiprovider as source and flat file as the target with some filter in between.
While defining the target as flat file, I have selected application server and logical file name.
Can any one please let me know how to create this file which should be selected from the list of files.
Thanks in advance..

Hi,
In order to create a file in the directory, you would need to write a ABAP program from your side.. like OPEN DATASET. or else Basis would help you to create this fro you.
Hope I understood your question...

Logical File creation in Logical path

Hi all,
I am after an info, how to create different logical file name in the same physical path.
Suppose I have physical path: X/claims/interface/outbound which is assigned to logical path LP
Now under this path I want to store some logical file say 1, 2, and 3
What would be the naming convention? & how to do it?
Any help would be highly appreciated.
Regards,
Kironmoy Banerjee.

Hi,
Use FM u2018FILE_GET_NAMEu2019 to assign the physical file name using a logical file name.
Remember you need to create u2018logical file nameu2019 using transaction u2013 FILE.
R/3 applications run on various platforms with various file systems. Hence we use platform-independent logical file names in our application programs.
Function module u2018FILE_GET_NAMEu2019 converts a logical file name to the corresponding physical file name and path for the hardware platform concerned.
For this conversion to work for different platforms, the definition of a logical file name must include a logical file path, which in turn is converted to different physical file paths, depending on the particular platform. The platform-specific file name returned by the function module is composed of the physical file path for the current platform and the physical file name associated with the logical file name. Placeholders in physical file and path names are substituted at runtime by the corresponding current values.
Example
logical file name: MONTHLY_SALES_FILE
physical file name: VALUES<PARAM_1>
logical path: SALES_DATA_PATH
physical path (UNIX): /usr/<SYSID>/<FILENAME>
physical path (Windows): C:\SALES\<FILENAME>.

Logical file path problem in lsmw

Hi folks,
I created logical file path in FILE tcode. its created and assigned physical file path to logical file path.
then i am assigning that logical file path into lsmw step (specify file step).
under specify file i am assigning into import data and convert data.
once read data step completed read data must be save under this physical file but data is not saving under this path.
can any one help me out this..
1.can any one help how to create physical file in file tcode
2.how to assigne that physical file to lsmw step specify file

Hi Srikanth,
There is no need to create the logical file path using the FILE transaction.
Under Specify file step, you need to give your local file path in LEGACY DATA Section.
Please check the below link in using the LSMW step by step.

Hope this helps.

In LSMW while executing the specify file step logical file name and path.

Hi ,
In LSMW , while executing the specify file step, logical file name and path is mandatory field to entry, but in some of other LSMW objects, these fields are not mandatory one, i want to know is it possible for me to do hide the logical file name and path field in specify file step.
thanks
Md nisar

Hi,
For some Transactions while executing the Specify file step Logical File and Logical Path are mandatory.
In this case Converted file will be stored in the application server. According to the specified Logical File and Logical path.
Hope this will help you....

Create logical file path and read it in main program

Hello Experts,
My requirement is, I have to read files from application server.
File path/ Directory is different in different system (systid). i have to read all files starting with (xyz*) from mentioned directory.
This path i must define in logical path.
Following are the steps i followed.
1) In FILE (TCODE) i have created a logical path and assigned a physical path to it.
2) I have created logical file ( I am not sure about this, as i dont have to create logical file, i just need to read file from above path starting with xyz*, but FM FILE_GET_NAME requires logical file name so i have created it).
3) I will pass logical file name to FM FILE_GET_NAME and recieve physical file path(with file name which i can ignore).
these all steps i found on SDN. but its not working.
FM FILE_GET_NAME is always returning same file path ( Not even close to what i have defined ).
I can not read data from Table path as it will return physical path as it is, but i need it replaced with system id.
Any suggestion will be really helpful.
Thanks in Advance.
Regards,
Amar

Hi Amar,
one difficulty defining physical path name is to know the right Syntax group.
For example if you habe OS Linux, you need Syntax Group UNIX here. In Table OPSYSTEM you can see, which OS (OPSYS) needs which FILESYS (Syntax Group).
If you always get a wrong physical path, this may be caused ba a wrong choice of the Syntax Group. Only the correct one will lead to the correct path.

Klaus
