Defining Logical Path and File Names (SAP Library

Defining Logical Path and File Names

Use

Archive files are stored in the file system under a physical path and file name that is derived from a user-definable logical path or file name. The definition can be divided into the following steps:

Definition of the logical path name
Definition of the logical file name
Assignment of the logical fine name for the archiving object

The system uses the logical file name ARCHIVE_DATA_FILE and the path name ARCHIVE GLOBAL PATH as defaults, which cover must cases. Consequently, the names only need to be changed if they have to be adjusted to meet special requirements.

Prerequisites

If you intend to transfer the archive files to a storage system using the Content Management Service, note that this storage system must have access to the archive files.

In the case of hierarchical storage management (HSM) systems, you must ensure that the archive files can be written to the file system of the HSM system.

Defining Logical Path Names

Call the transaction FILE.

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

Mark an existing path name, such as ARCHIVE_GLOBAL_PATH, or choose New entries to enter a new path name - this should be as meaningful as possible.

Double click the dialog structure Logical file path definition in the substructure Assignment of Physical Paths to Logical Path. Select a syntax group or create a new syntax group.

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

You can use the F1 key in the Physical path field to obtain a list of all possible parameters.

When assigning path names, the symbol <FILENAME> must appear at the end. This symbol is replaced at runtime by the physical file (or path) name. No part of the physical file name in the path name must be defined.

You have created the subdirectory "data_archiving" for archive files in the global directory. You then specify a path name:

<P=DIR_GLOBAL>/data_archiving/<FILENAME> (Syntax group UNIX)
<P=DIR_GLOBAL>\data_archiving\<FILENAME> (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.

Save your entries.

Defining Logical File Names

Logical file names can be defined as client-specific (transaction SF01) or client specific (transaction FILE). A client-specific definition always overrides a cross-client definition. Ensure, therefore, that in every client any unnecessary client-specific definitions are deleted.

The following describes the procedure for creating a cross-client definition using the transaction FILE. You create the client-specific definition in the same way using transaction SF01.

Call transaction FILE for cross-client file names.

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

For client-specific definitions, from the initial screen for Archive Administration, choose: Customizing à Basis-Customizing à Client-specific File Names

Mark an existing file name, for example ARCHIVE_DATA_FILE, or choose New entries to enter a new file name. The file name should reflect its function.
Double click on the dialog structure Logical file name definition, cross-client.
You access the screen Change View "Logical file name definition, cross-client": Overview
Maintain the fields Physical file and Logical path.

In the Physical file field, enter the required physical file name. For an overview of the possible parameters, refer to the F1 help.

The following parameters are of particular interest here:

PARAM_1: Two-character application abbreviation (for example, HR, CO, MM) for the classification of the archive files in the system. The value of the definition is determined from the relevant archiving object at runtime.

PARAM_2: Single-character alphanumerical code (0-9, A-Z). If, when creating a new archive file, an existing file with an identical physical name would result in a conflict, the ADK increases this value by 1. This value must, therefore, always be a part of the physical name.

PARAM_3: This parameter is filled with the name of the archiving object at runtime. In archive management, this enables you to check the file contents or to store the archive files by archiving objects.

To enable maximum space in the name range for the archive file, the following entry is recommended:

<PARAM_1>_<DATE>_<TIME>_<PARAM_2>.ARCHIVE

In the Logical Path field, you assign the previously defined logical path name to the current logical file names. You can assign a logical path name to several file names.

Save your entries.

To display the path name and file name definitions and their specifications for the relevant syntax groups, go to transaction SF07.

Assigning a logical file name to the archiving object

Once the logical path name and file name have been defined, the logical file name must be assigned to the archiving object. Proceed as follows:

In the Archive Administration initial screen (transaction SARA), enter the name of the archiving object and choose Customizing. Under Archiving object-specific Customizing, choose Technical Settings.
In the Logical file name field, enter the required logical file name.
