Description
So that the database optimizer can find the best access strategy to thedata, the statistics have to be kept as up-to-date as possible. This isdone with update statistics. So that the database administrator doesnot have to provide the statistics, ADABAS for R/3 works with implicitupdate statistics. As soon as the database kernel detects obsoletestatistics when a database object is accessed, they are updatedimplicitly.
So that the current statistics can be viewed from R/3, regardless ofthe database system, non-database-specific R/3 tables are created byCCMS.
These CCMS tables are not maintained directly from the database kernel.This means that the ABAP RSADAUPD must view the database system tablesat regular intervals, and log the implicit statistics runs in the CCMStables. There is no explicit update statistics.

Precondition
Use transaction SM36 to schedule ABAP RSADAUPD at regular intervals,(for example, monthly).

Output
For the following information on the adjustment, see the job log intransaction SM37
- When was the last adjustment
- How many tables were affected by the adjustment
- Which tables were adjusted
