RSMSS_ANALYZER_MSG016 - Overview

• Message type: E = Error

• Message class: RSMSS_ANALYZER_MSG - Messages for RSMSS_ANALYZER

• Message number: 016

• Message text: Unpartitioned F-Fact tables that can be partitioned

Check description
This check returns a list of unpartitioned F-Fact tables. You can
partition selected tables with the repair option. Unpartitioned F-Fact
tables can reside from older BW releases or due to problems during
system copies.
<ZH>Partitioning an F-Fact table should only be executed by SAP Support.
</>
Repair description
With the repair option, you can partition an F-Fact table. The original
table is backed up to a /BI0/06* temporary table that is not
automatically deleted after the partitioning has been completed.
The data of the original table is copied to the new partitioned table in
several data packages based on the cube request. Each package transfer
is committed in the database.
In the event of an error - for example, a full transaction log during
data transfer ? you can re-run the repair. The repair continues with the
package that aborted during the previous run.
After all data has been transferred, a data consistency check is
triggered that compares the number of rows in the new partitioned table
with the number of rows in the backup table.
The complete partitioning process is documented in the application log
and in the repair result. There you can also find the names of the
backup tables as well as the packages that have been transferred.

RSMSS_ANALYZER_MSG016 - Details

• The SAP error message RSMSS_ANALYZER_MSG016 indicates that there are fact tables in your SAP system that are not partitioned but could benefit from partitioning. This message is part of the SAP BW (Business Warehouse) system and is related to the performance optimization of data models.
  
  Cause:
  The primary cause of this error message is that certain fact tables (F-Fact tables) in your data model are not partitioned. Partitioning is a technique used to improve query performance and manageability by dividing large tables into smaller, more manageable pieces (partitions). When a fact table is large and frequently accessed, not partitioning it can lead to performance issues, such as slow query response times.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Analyze the Fact Tables: Identify the specific fact tables that are generating this error message. You can use the SAP BW modeling tools to review the characteristics of these tables.
