logical file path

The (platform-independent) logical file path is evaluated at runtime to get the (platform-dependent) physical path (see Assignment of Physical Paths to Logical Path).

Two examples of this are:

· Logical file path: BW_OLAP_CACHE

Name: BW OLAP Cache

· Logical file path: BW_OLAP_CACHE_SPAN

Name: BW OLAP cache cross-application server

Assignment of Physical Paths to Logical Path

At runtime, the physical path assigned for the corresponding operating system platform is generated from the logical file path.

Since the physical path is platform-dependent, the customer must set it her/himself. The closer the file is to the application server or, with the cross-application server cache mode, to the application server, the faster it can be found and read.

Log(ical) path: BW_OLAP_CACHE

Name: BW OLAP Cache

Syntax group: UNIX (all Unix platforms)

Phys(ical) path: /usr/

External parameter 1 (sequence number in HEX)

how to create logical file path

1. Call transaction FILE.

Alternatively, from the initial screen for Archive Administration (transaction SARA), choose: Customizing ® Basis-Customizing ® Cross-Client File Name/Paths .

2. Mark an existing file name, for example, ARCHIVE_GLOBAL_PATH, or choose New entries to enter a path name. The name should reflect its function.

3. Double click the dialog structure Logical File Path Definition in the substructure Assignment of Physical Paths to Logical Path. Double click to select a syntax group or create a new syntax group.

4. Assign a physical path name to the logical path name.

When assigning path names, the symbol (Syntax group WINDOWS NT)

In a heterogeneous system landscape (such as UNIX and Windows NT servers) all system-specific syntax groups must be maintained. Ensure that the definitions for the various syntax groups point to the same directory.

5. Save your entries

hi,

you can creat logical file path & name & assign a physical file path &

name using FILE transaction.

then in abap using function modules like

FILE_GET_NAME Assign the Physical File Name Using a

Logical File Name

FILE_GET_NAME_AND_LOGICAL_PATH Assign physical file names and get logical

path

FILE_GET_NAME_USING_PATH Generate a complete file name with file

name and logical path

get physical path & file name, so in case of change in dir structure don't

need to change ABAP.

Hope this helps, Do reward.
