Logical File names for OHS

Hi all,
I wanted to create the files names dynamically
I know we can use transaction file and define a logical name with variables and assign value sto the variables to get the physical name.
my requirement is to fetch different values for the variables as well. for example : let ssay I have to create two data files using a process chain . both should have same time stamp at the end of the file.
I 'm planning to store this timestamp in a table. so during run time I want FILEname1_timestamp and Filename2_timestamp.
wher etimestamp is the same value for both files. but the prefix is different.
please let me know a optimum way to create this in BI7.0

I store this as a variable in PARAMVALUE table and us ethis in the logical file name of the File in transaction FILE.

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

Infpackage with logical file name having current year and month

Hello all,
I am using the FILE transaction to maintain the logical file name for infopackage loads in BW.This logicalfile name is to be assigned to physical csv file in AL11 directory.
This csv file would be having the current month and date at the end of the name for e.g for the month of April 2008,the file name would be say xx_200804.csv.I wanted to know if by using the palceholder <YEAR><MONTH> in the physical file name ,would the current month date and month be automatically concatenated at the end of file name ?Has anyone used this option before?

yes it does work,i tried out finally and the system picks current month and year

LSMW - Create Logical File Name so that the physical file name is automatic

Hello,
In LSMW, I do not want to create a logical file name for each project. I would like the logical file name to automatically assign the physical file to the *.lsmw.conv of the project being executed. Is there a way of doing that? If so, could someone share?
Regards, Dean.

not possible to create the logical file name to physical file name automatiically.
because the logical file name created like PROJECT name + SUB PROJECT name +OBJECT NAME .*.lsmw.conv
if you change the object name the file will be change....

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

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....

Logical file name or logical path name incorrectly defined

Dear All,
We are doing archival in our IDES for test purpose before we do it to our Production.
Steps Performed
Copied AM_ASSET archive object to ZAM_ASSET
Logical Path
Logical path    ZAM_ASSET
Name            Asset
Syntax group    UNIX       Unix compatible
Physical path   /archive/test/<FILENAME>
Logical File Name
   Logical file    ZAMASSET
   Name            Asset
   Physical file   FI_<MONTH>_<DAY>.txt
   Data format     ASC
   Applicat.area   AM
   Logical path    ZAM_ASSET
But when we run the WRITE though SARA , in the job log we get the following
Logical file name or logical path name incorrectly defined
When generating a file name for an archive file that is to be created, the system determined that the logical file name FIAA_ARCHIVE_DATA_FILE or the logical path name ARCHIVE_GLOBAL_PATH was defined incorrectly.
But we have maintained a Logical name ZAMASSET , so we are unable to change the location of archived file and as well as the format.
So is there any setting we need to maintain apart from the logical file name and logical file path.
Suggestions are highly appreciated.
Thanks in anticipation

hi,
follow this steps :
- transaction SARA
- enter authorization objects, eg SD_VBAK
- hit button CUSTOMIZING
- Archiving Object-Specific Customizing: execute Technical Setting
- field Logical File Name enter or select ARCHIVE_DATA_FILE
- leave CONTENT REPOSITORY as blank if you are not using 3rd party for storing (eg. IBM Tivoli)
- back to customizing
- from Basis Customizing, execute : Cross-Client File Names/Paths
- on Logical FIle Path Definition, highlight (select) ARCHIVE_GLOBAL_PATH on the right pane
- double click on the Assignment of Physical Paths to Logical Path on the left pane
- double click on OS used, eg. UNIX, define Physical Path where archive file (on WRITE process) will be stored
- save changes made
- double click Logical File Definition, Cross Client on the left pane
- double click ARCHIVE_DATA_FILE on the right pane
- make sure that logical path is already set to ARCHIVE_GLOBAL_PATH
- save changes made
this setting also can be done using transaction FILE
we have experienced on this case using SAP standard archiving (SARA, SARI) and everything is fine with this setting above.
hope it 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.

Durgesh.

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

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
SFIL

Archiving : Change of Logical File Name & physical path

Hello friends,
We are doing archiving for a Z* archiving object.
We run a write job(not delete job till now) for this archiving object and it created archive files in .../SYS/GLOBAL directory as was expected from settings of Logical File Name and hence physical path corresponding to it. So far no problem..
Now, requirement is to change this path and for this i created a new Logical File Name with a different physical path.
My concern is, about already archived data in older path. Should i only run delete job for that session ?
Or should i copy the archive files to new path and then start delete job OR do a write job once again..
please suggest.
thanks
ashish

Hello Juan,
Ok, i can copy the files, those are not too many as we did it only for 2 months selection.
Can i go for write job again for same selection ? If yes, probably it will create a new session.. correct ? and then i will go for deletion for new session.
If this is also correct way, i want to do this.. as till now this has been one for only 2 months and we are going to do for 8 yrs.
One more question, will the be any problem for having 2 sessions for same selection.. means 2 write or archive job for same selection.
thanks
ashish
