Maintaining Collection and Reorganization Schemata (Standard Setting) 

Use

Collection and reorganization schemata specify how long data assigned to this schema are to be stored in the Central Performance History (CPH) with which resolution. Predefined schemata are delivered with the CPH. These fulfill most requirements. You have two options for creating new schemata, or displaying or changing existing schemata:

·        Use the expert setting (see Maintaining Collection and Reorganization Schemata (Expert Setting)).

·        Use the standard setting described here.

In the standard setting, you cannot create new schemata from scratch. Instead, you can use an existing schema as a template for your own schema, by changing the storage period of the various aggregates. If you want to create your own schema, we recommend that you use one of the predefined SAP schemata as a template. You can recognize these templates, as they always have the prefix SAP. You will only have to use the expert setting in rare cases.

Procedure
