Dynamic Physical File names on AL11

Question

Hi,
I have the following requirement.
I have almost 25 files to be exported onto AL11 using OpenHub from various infoproviders and I used the "Logical File name" option to do it.
I would like to have the physical file names as " ZINFOPROV_<DATE>_<TIME> " and Infoprovider tech. name should get populated dynamically somehow.
I was looking at the following thread for the same req : Re: Open Hub File name Change
I defined my logical file name definition as
Logical file    Z_SALES
Name            Used for SALES
Physical file   ZINFOPROV_<DATE>_<TIME>
Data format     ASC
Applicat.area   BW
Logical path    Z_SALES
I would like this ZINFOPROV populated dynamically.
Any have any inputs/suggestions.
Regards,
Kumar

Hi Kumar,
You have a very good question and also shown the viewer of your post the way forward. Well i got your answer from your question only. Considering <DATE> as one kind of literals, you need a literal to identify the infoprovider as one part of your filename. Now my answer is not direct resolution but it may lead you to your answer. Here are the list of other literals that might be of use to you.....
Extract from the help.......
Physical path name
Platform-specific physical path under which files are stored. It most contain the reserved word <FILENAME> as a placeholder for the file name. IT can also contain further reserved words (see below).
Use
The physical path name is used by the function module FILE_GET_NAME at run time to create a complete platform-specific file name.
Procedure
Specify a path. You can include the following reserved words in pointed brackets. These are replaced with current values at runtime.
Reserved Word    Replacement Text
<OPSYS> Operating system in call
<INSTANCE> R/3 application instance
<SYSID> R/3 application name in SY-SYSID
<DBSYS> Database system in SY-DBSYS
<SAPRL> R/3 release in SY-SAPRL
<HOST> Host name in SY-HOST
<CLIENT> Client in SY-MANDT
<LANGUAGE> Log on language in SY-LANGU
<DATE> Date in SY-DATUM
<YEAR> Year in SY-DATUM, 4-character
<SYEAR> Year in SY-DATUM, 2-character
<MONTH> Month in SY-DATUM
<DAY> Day in SY-DATUM
<WEEKDAY> Day of the week in SY-FDAYW
<TIME> Time in SY-UZEIT
<STIME> Hour and minute in SY-UZEIT
<HOUR> Hour in SY-UZEIT
<MINUTE> Minute in SY-UZEIT
<SECOND> Seconds in SY-UZEIT
<PARAM_1> External parameter 1
<PARAM_2> External parameter 2
<PARAM_3> External parameter 3
<P=name> Name of a profile parameter (see Report RSPARAM for valid values)
<V=name> Name of a variable (stored in variable table)
<F=name> Return value of a function module Naming convention for this function module: FILENAME_EXIT_name
<Y=name> Return value of a function module Naming convention for this function module: Y_FILENAME_EXIT_name
<Z=name> Return value of a function module Naming convention for this function module: Z_FILENAME_EXIT_name
Examples
Local directory for temporary files under Windows NT: D:\GLOBAL\ARCHIVE\<PARAM_1>\<FILENAME>
Local directory for temporary files under DOS:C:\TMP\<FILENAME>
Local directory for temporary files under UNIX: /usr/<SYSID>/local/tmp/<CLIENT>/<FILENAME>
Dependencies
The function module for the run-time variable <F=name> must meet the following requirements:
Name
The name must begin with "FILENAME_EXIT_".
Parameter
An export parameter with the name "OUTPUT" must exist.  No structure may exist for this parameters.
Import parameters are only supported if they have default values.
Table parameters are not supported.
Valid example: FILENAME_EXIT_EXAMPLE.
I hope this leads you to your resolution.
Regards
Raj
