How To Fix SMMSS_DDIC009 - FILEGROUP is not set for the table and the clustered index

SAP Error Message - Details

• Message type: E = Error

• Message class: SMMSS_DDIC - DDIC Messages for Microsoft SQL Server

• Message number: 009

• Message text: FILEGROUP is not set for the table and the clustered index

What causes this issue?

You have set CLUSTERED YES for an index; FILEGROUP is neither set for
the index nor the table. However, the table and index exist in the
database and are located in different filegroups. During conversion,
the table would first be created in its current filegroup and then
moved to the filegroup selected for the index. Depending on the size of
the table, this could be very expensive.

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?

If you do not want to convert the table, but rather move it into the
filegroup you selected for the index by creating a new index (activate
and adjust database) for which you have set CLUSTERED YES, you do not
have to do anything. However, if you want to convert the table, you
should set CLUSTERED YES for the filegroup of the index.

• What is the cause and solution for SAP error message SMMSS_DDIC009 - FILEGROUP is not set for the table and the clustered index ?

  The SAP error message SMMSS_DDIC009 indicates that there is an issue with the database configuration related to a specific table and its clustered index. The error message states that the FILEGROUP is not set for the table and the clustered index, which is typically encountered in the context of SAP systems that use Microsoft SQL Server as the database.
  Cause:
  This error usually arises due to one of the following reasons:
  
  
  Missing Filegroup Configuration: The table or its clustered index is not assigned to a specific filegroup in the SQL Server database. In SQL Server, a filegroup is a logical structure that groups database files for data storage.
  
  
  Database Migration or Upgrade: If the database was migrated or upgraded, the filegroup settings may not have been properly configured for the new environment.
  
  
  Database Corruption: In rare cases, database corruption or misconfiguration can lead to this error.
  
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Check Filegroup Configuration:
  
  Open SQL Server Management Studio (SSMS).
  Connect to the database instance.
  Navigate to the database in question.
  Check the properties of the table and its clustered index to see if they are assigned to a filegroup.
  
  
  
  Assign Filegroup:
  
  
  If the table or index is not assigned to a filegroup, you can create a new filegroup or use an existing one.
  
  
  Use the following SQL command to create a new filegroup (if needed):
  ALTER DATABASE [YourDatabaseName] ADD FILEGROUP [YourFileGroupName] DEFAULT;
  
  
  Then, you can create or alter the table/index to specify the filegroup:
  CREATE TABLE [YourTableName] (
      [Column1] INT,
      [Column2] VARCHAR(100),
      ...
  ) ON [YourFileGroupName];
  
  CREATE CLUSTERED INDEX [YourIndexName] ON [YourTableName] ([Column1]) ON [YourFileGroupName];
  
  
  
  
  Recreate the Table/Index:
  
  If the above steps do not resolve the issue, you may need to drop and recreate the table or index with the correct filegroup settings.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes or documentation that may provide additional guidance or specific instructions related to this error.
  
  
  
  Backup and Test:
  
  Always ensure you have a backup of your database before making structural changes.
  Test the changes in a development or test environment before applying them to production.
