ADM100 Lesson: Fundamentals of <strong>SAP</strong> Data Archiving<br />

hand, must, among other things, clarify which data can be archived, when<br />

this archiving should be performed (for example, not before a year end)<br />

and whether (possibly also how) the archived data is to be accessed.<br />

Schematic Process of a Data Archiving<br />

The actual data archiving is a process in three steps:<br />

1. Creating the archive file(s): In the first step, the write program creates<br />

one (or more) archive file(s). The data to be archived is then read from<br />

the database and written to the archive file(s).<br />

2. Storing the archive file(s): After the write program has completed the<br />

creation of the archive files, these can be stored.<br />

Up to <strong>SAP</strong> <strong>Basis</strong> 4.6B (inclusive), it is only possible to use the delete<br />

program to delete data from the database that it was first possible to<br />

read from the archive file in the File system. As of <strong>SAP</strong> <strong>Basis</strong> 4.6C, it<br />

is also possible to read the data to be deleted from the archive file of<br />

the storage system; that is, to store the data before the deletion.<br />

3. Deletingthedata-thedeleteprogramfirstreadsthedatainthe<br />

archive file and then deletes the corresponding records from the<br />

database.<br />

It is possible to run a preprocessing program before the actual archiving.<br />

Preprocessing programs can, for example, set deletion indicators (such as<br />

in PPPM/CO), or can also provide information about whether data can<br />

be archived (SD).<br />
