Logical file names in your application programs

hi all ,
how i used FILE_GET_NAME function module in my program ,to logical file name for platform-independent files.
thank you.

Hi Pawan,
you can use as below:
DATA: gv_physicalpath TYPE path-pathextern.
CONSTANTS: gc_logicalpath TYPE filepath-pathintern
                         VALUE 'MMIM_PHYSICAL_INVENTORY_DOCUMENTS'.
* Get corresponding physical path for the logical path
PERFORM get_physical_path USING gc_logicalpath
                         CHANGING gv_physicalpath.
FORM get_physical_path USING    p_gc_logicalpath
                        CHANGING p_gv_physicalpath.
CALL FUNCTION 'FILE_GET_NAME'
    EXPORTING
      logical_filename = p_gc_logicalpath
      operating_system = sy-opsys

FU FILE_GET_NAME
Text
Assign the Physical File Name Using a Logical File Name
Functionality
R/3 applications run on various platforms with various file systems. This function module enables you to use platform-independent logical file names in your application programs.
Based on definitions maintained in customizing tables for platform-independent file names, the function module 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>
Example 1
Get file name for UNIX platform
(current system: K11)
CALL FUNCTION 'FILE_GET_NAME'
EXPORTING
LOGICAL_FILENAME = 'MONTHLY_SALES_FILE'
IMPORTING
FILE_NAME = FILE
FILE_FORMAT = FORMAT.
Result:
FILE = /usr/K11/VALUES
FORMAT = WK1
Example 2
Get file name for UNIX platform, passing a parameter
(current system: K11)
CALL FUNCTION 'FILE_GET_NAME'
EXPORTING
LOGICAL_FILENAME = 'MONTHLY_SALES_FILE'
PARAMETER_1 = '_TST'
IMPORTING
FILE_NAME = FILE
FILE_FORMAT = FORMAT.
Result:
FILE = /usr/K11/VALUES_TST
FORMAT = WK1
Example 3
Get file name for WINDOWS platform, with file name extension
CALL FUNCTION 'FILE_GET_NAME'
EXPORTING
LOGICAL_FILENAME = 'MONTHLY_SALES_FILE'
WITH_FILE_EXTENSION = 'X'
IMPORTING
FILE_NAME = FILE
FILE_FORMAT = FORMAT.
Result:
FILE = C:\SALES\VALUES.WK1
FORMAT = WK1
Notes
All definitions needed for the platform-independent assignment of file names are maintained client-independently with transaction FILE. Logical file names (but not logical file paths) can also be defined specifically for the current client with transaction SF01. Transaction SF07 generates a list of current definitions.
The following concepts are used in the platform-independent assignment of file names:
Logical file name
A descriptive name for a file which is associated with these values:
physical file name
file format
logical file path.
If no logical file path is specified, the function module returns the physical file name only; placeholders are substituted by current values.
Physical file name
The physical file name may contain placeholders.
Logical file path
A descriptive name for a path which is associated with these values:
syntax groups (groups of operating systems)
physical file paths.
Physical file path
The physical file path is defined for a particular syntax group. It must contain the reserved word <FILENAME> as a placeholder for the file name. It may also contain other placeholders.
Operating system
Presentation server and application server can run under different operating systems. The current value for the application server can be obtained from the system field SY-OPSYS, the value for the presentation server by calling function module WS_QUERY.
Both operating systems must be defined and assigned to a syntax group.
Syntax group
Group of operating systems with a common syntax for file and path names (e.g. HP-UX and SINIX).
Placeholder
Reserved words, set in angle brackets, which can be included in physical file and path names (e.g. <DATE>, <FILENAME>). You can find information on possible reserved words in the online help (F1 help) for the fields physical file name and physical file path when maintaining platform-independent file names with transaction FILE.
If the logical path associated with a logical file name does not specify a physical path for the current operating system (syntax group), the path stored in the profile parameter DIR_GLOBAL of the current system is used for generating a complete platform-specific file name.
Parameters
CLIENT
LOGICAL_FILENAME
OPERATING_SYSTEM
PARAMETER_1
PARAMETER_2
PARAMETER_3
USE_PRESENTATION_SERVER
WITH_FILE_EXTENSION
USE_BUFFER
ELEMINATE_BLANKS
EMERGENCY_FLAG
FILE_FORMAT
FILE_NAME
Exceptions
FILE_NOT_FOUND
Function Group

Assign Logical file name for the physical file path through Program

Hi all,
I am having a physical file which is getting generated dynamically. It is having the date and time stamp in its name which is added at runtime.
Now I need to assign a logical file name for the physical file path through the program.
Is there any FM or any other method to assign the same.
Gaurav

I think it is not possible. becuase the date & time added at runtime. so if you check the table PATH you can find filename and their definitions

How to create the logical file name

Hi All,
    I have requirement where i need to post the Inventory Management data. for this i need to execute std. program RM07MMBL which is having logical file name in the selection screen. but i have placed my input file in application server.
   Can any one tell how to create the Logical filename which refers the physical path. I also tried <b>t-code SF01 & Table - FILENAMEC</b>I and found that we need to add an entry in this table but i really dont know how we have to do since this table cannot be maintained in SM30 also..
Help Me.
Thanks in Advance!...
Regards,
Ramkumar

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
Hope this helps

How to use variables in logical file name definition FILE

Hi Friends,
How can I use variables in logical file name definition (tcode FILE). The requirement is to pass value in these variables (based on selection criteria), and use it as part of file name. You quick response will be highly appreciated.
Thanks,
Kuldeep Joshi

Hi,
Thanks for your reply.
In detail, the scenario is like I have created an Open Hub. Its working fine. Now I am planning to execute this open hub using process chain and for that I have to define the file output on application server along with logical file name (using tcode FILE). The logical file name contains two variables (defined in FILE) i.e. z_dept and z_fiscperiod.
Filter value in DTP ( I will read these values from Ztable using routine )
Dept = R&D
Fisc period = 004/2009
Variables defined in tcode FILE:
z_dept for Dept
z_fiscperiod for Fiscal Period
Logical file name : <z_dept>_<z_fiscperiod>.csv
Now the challenge is to populate filter values in these two variables so that the filter value can be used for naming the output file.
My last option is to read/update SAP standard table used for storing variable values (i.e. PARAMVALUE)
Please let me know if you can help me in this issue OR is there any standard method/FM to populate value in these variables
Thanks,
Kuldeep

Error - Logical file is not part of database. Use RESTORE FILELISTONLY to list the logical file names

I made a script to restore .bak or backup files. It works for some databases, but not for one. How do I make it work for any type of .bak file ? This is in sql server 2008. The error message is -
Msg 3234, Level 16, State 1, Line 1
Logical file 'Northwind_Data' is not part of database 'Northwind'.
Use RESTORE FILELISTONLY to list the logical file names.
Msg 3013, Level 16, State 1, Line 1

Hello,
The issue you are facing might be related to below link
http://support.microsoft.com/kb/2487231/en-us
As per link this is known issue.Can you please check service pack level of SQL Server 2008 .It should be SP3.Please apply SP3 and see if the error subsides.
Also error suggests logical file name 1 which you are giving is not part of the backup set from which you are trying to restore.You should first use below query to determine right file then proceed with restoration of the same.
restore filelistonly from disk='C:\Program Files\Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL\Backup\Northwind.bak'
if file ID is 3 may be your restore script would be like below
F DB_ID('Northwind') IS NULL
BEGIN
RESTORE DATABASE [Northwind]
FILE = N'Northwind_Data'
FROM
DISK = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL\Backup\Northwind.bak'
WITH FILE = 3,
MOVE N'Northwind_Data'
TO N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL\DATA\Northwind.mdf',
MOVE N'Northwind_Log'
TO N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL\DATA\Northwind_0.LDF',

Technical Name of Openhub in logical file name

Hi All,
I am creating a few open hub flatfiles for a client. I want to use logical file names to create the files on the application server.
I want to create one logical file name which creates a file like <"Open Hub Technical name">_<DATE>_<TIME>.csv.
Now i can't find a way to include the openhub technical name in the file name.
It says in F1 that i can use a function module named FILENAME_EXIT_* that will be called in the function module FILE_GET_NAME.
Does anybody know about the coding that can be used for this? I have just basic ABAP knowledge on this one. Or is there perhaps another way on this.
Let me know!
Thanks in advance!
Best regards,
F Geldof.

Hi guys,
Thanks for your answers first of all.
I don't want to store the technical name of the openhub in the logical file name....i want this to be determined dynamically, depending on the openhub that is used with this logical file name.
I was wondering were i can fetch the openhub technical name during the execution of the DTP on the openhub / when also the function module FILE_GET_NAME is being ran.
Let me know!
Thanks in advance!

Freek

Hoe to logical file name using "FILE" transcation

I want to create a logical file name using "FILE" transaction , i have file path '/xfer/OUT/IDD0230 ' that cureently hard coded in program but i want to avoid hard code .

You need to go to FILE transction, create new entry.
You need to specify Physical name i.e value hardcoded in your program
and corresponding new Logical Path which enduser will be entering.
In code u ned to decode Logical path to physical path as its actual path.
Award points if helpful.

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....

To test how can we use the opt 'logical file name' to name the file based

Hi Sir/Madam,
to test how can we use the opt 'logical file name' to name the file based on the selection made in the dtp run for extracting data as flat file.

Hi Vishali,
In the DTP select the file location as application server and give the logical file path. The actual file and logical path can be created using transaction "FILE" and "AL11".
Rest of the process is same as that of extraction from local file.

OHD - Logical File Name

Hello all,
I have a question about using a logical file name in an OHD (BI 7.0). Because we need to transport the OHD to a different server, we cannot use the File option in defining the OHD. We need to use the option, Logical File. In t-Code FILE, we cannot seem to create a physical path that the OHD recognizes.
This is the path in AL11 where we want the file to end up: /usr/sap/BIP/DVEBMGS17/work/GGLF010.CSV with a server of prdsap01. We are creating the OHD in a different system with a different server and path. How should the physical path (mapped to the logical path) be defined. I know we have to use <FILENAME> to represent the OHD output file (GGLF010). What variables do we use for the rest of the path? Do the variables have to be specifically defined or are they delivered by SAP?
Any help would be greatly appreciated!
Sheila

I don't know if this is relevant to this issue, but seems related.
When using OHD I noticed that two files are produced, the data file and the header file, unfortunatly when writing to the application server the file names output are identical. Therefore the header file overwrites the data file - anyone else experience this???
It is not possible to do anything about this using FILE settings so as a workaround (becasue I couldn't find/ an OSS note) I modified the standard class to ensure the data and header files names were unique:
METHOD: DETERMINE_FILENAME of class CL_RSB_FILE_GENERAL
o_filename_ctrl = l_filename.
*{ INSERT
*SAP BUG RENAMING HEADER FILE ELSE DUPLICATE FILES WILL OCCUR!!!
REPLACE '.CSV' IN o_filename_ctrl with '_HDR.CSV'.
*} INSERT
clear n_requid_current.
endmethod.
This assumes that the file output has .CSV as a file extension. This worked and now I get both the header and the data file.
If anyone could let me know if you have experienced this and how you resolved it would be nice.
cheers,
Asep

Regarding assignment of physical path to logical file name

Hi All,
We have created one logical file name and assigned physical path to it in FILE tcode.
IN PATH table also these details got updated with correct logical file name & physical path.
But in my program when i have used FILE_GET_NAME F.M to retrieve physical path from logical file.
Here this F.M is not returning anything.
What is the issue over here.
We are working in ECC 6.0
Can anybody resolve this issue!
