Use
Data archiving can be used to remove mass data from your productive database so that the data can be used for analysis at a later date. Before beginning to archive data, it is generally a good idea to check if you want to avoid creating data, aggregate data or simply delete data. Archiving is used for data that cannot be avoided and that cannot simply be deleted.
Archiving data at the right time enables you to keep your database to a manageable size, making it faster to save data and thereby improving performance. Data archiving is particularly important for retailers as large amounts of data are generated in a very short period of time.
When implementing SAP Retail, it is recommended that data archiving is productive immediately after an SAP Retail system goes productive. This means that it is a good idea to schedule archiving for your most important background jobs at regular intervals. The duration of an archiving project is normally six months. It is therefore imperative that you trigger your archiving project as soon as possible after going productive with SAP Retail.
Ensure that you start your archiving project at the correct time, if possible immediately after your system goes productive. Archiving projects are often started after a system has gone productive and a high percentage of the database capacity is already filled with data. When this is the case, it is important that the following questions are answered as soon as possible, for example:
Integration
Data archiving in SAP Retail is handled in the same way as data archiving in the non-Retail environment. It is based on SAP archiving objects and generic SAP tools.
