How To Fix RS_DB_DB6621 - Table &1 without modification state index, but secondary indexes enabled

SAP Error Message - Details

• Message type: E = Error

• Message class: RS_DB_DB6 - DB6-Specific Messages in SAP BW

• Message number: 621

• Message text: Table &1 without modification state index, but secondary indexes enabled

What causes this issue?

The BW check program has detected a BW object that has no modification
state index. However, in your system, secondary indexes for
column-organized BW objects are enabled, which means that every
column-organized BW object should have a modification state index.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

You can use program <NP>DB6CONV </>to generate the missing modification
state indexes. Before you use the program, familiarize yourself with its
functions, as the program does not only generate indexes for selected
objects, but, depending on your selections, also for the entire system.
For more information about secondary indexes and the program, see SAP
Note 2555566.

• What is the cause and solution for SAP error message RS_DB_DB6621 - Table &1 without modification state index, but secondary indexes enabled ?

  The SAP error message RS_DB_DB6621 indicates that there is an issue with a database table in the context of the SAP BW (Business Warehouse) system. Specifically, the message states that the table (denoted as &1) does not have a modification state index, but secondary indexes are enabled. This can lead to performance issues or data inconsistencies when querying the table.
  Cause:
  
  Modification State Index Missing: The modification state index is crucial for tracking changes in the data. If it is missing, the system cannot efficiently manage updates or changes to the data in the table.
  Secondary Indexes Enabled: The presence of secondary indexes implies that the system expects to optimize data retrieval based on certain fields. However, without a modification state index, the system may not be able to maintain these indexes properly.
  Table Configuration: The table may not have been configured correctly during its creation or modification, leading to the absence of the required modification state index.
  
  Solution:
  
  Check Table Configuration: Review the configuration of the table in question. Ensure that it is set up correctly to include a modification state index.
  Recreate the Modification State Index: If the modification state index is missing, you may need to recreate it. This can typically be done through the Data Warehousing Workbench (transaction RSA1) or using specific database administration tools.
  Adjust Index Settings: If secondary indexes are not needed, consider disabling them to avoid the error. However, this may impact performance, so it should be done with caution.
  Data Consistency Check: Run consistency checks on the data to ensure that there are no underlying issues that could be causing the error.
  SAP Notes and Support: Check for any relevant SAP Notes that may address this specific error. SAP frequently releases updates and patches that can resolve known issues.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench) or SE11 (Data Dictionary) to manage and configure database tables.
  SAP BW Documentation: Refer to SAP BW documentation for best practices on table management and index configuration.
  Performance Monitoring: Monitor the performance of the BW system after making changes to ensure that the issue is resolved and that there are no new performance bottlenecks.
  
  If the problem persists after trying the above solutions, it may be necessary to consult with SAP support or a database administrator for further assistance.
