SAP Error Message - Details

• Message type: E = Error

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

• Message number: 548

• Message text: DSO &1: Non-unique index &2 is defined as unique in metadata

What causes this issue?

For this DataStore object, an attempt was made to create a unique
user-defined index. However, there was already a distribution key with
the same fields available. The system therefore created the user-defined
index as non-unique.

System Response

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

• What is the cause and solution for SAP error message RS_DB_DB6548 - DSO &1: Non-unique index &2 is defined as unique in metadata ?

  The SAP error message RS_DB_DB6548 indicates that there is a discrepancy between the metadata definition of a DataStore Object (DSO) and the actual data in the database. Specifically, it suggests that a non-unique index is defined as unique in the metadata for the DSO. This can lead to issues when trying to load or process data in the DSO.
  Cause:
  
  Metadata Mismatch: The metadata for the DSO indicates that a certain index should be unique, but the actual data in the DSO contains duplicate entries for that index.
  Data Load Issues: If data was loaded into the DSO without proper checks for uniqueness, it could lead to this error.
  Changes in Data Model: If the DSO was modified (e.g., fields were added or changed) without properly adjusting the data or the metadata, this could lead to inconsistencies.
  
  Solution:
  
  
  Check Data for Duplicates:
  
  Query the DSO table in the database to identify any duplicate entries that violate the uniqueness constraint.
  Use SQL queries to find duplicates based on the fields that are supposed to be unique.
  
  
  
  Adjust Metadata:
  
  If the duplicates are valid and should be allowed, consider adjusting the metadata to remove the uniqueness constraint.
  This can be done in the Data Warehousing Workbench (transaction RSA1) by modifying the DSO definition.
  
  
  
  Data Cleansing:
  
  If duplicates are not valid, you will need to cleanse the data. This may involve deleting or merging duplicate records to ensure that the DSO contains only unique entries.
  
  
  
  Re-activate the DSO:
  
  After making the necessary changes, you may need to re-activate the DSO to ensure that the changes take effect.
  
  
  
  Test Data Load:
  
  After resolving the issue, perform a test data load to ensure that the error does not reoccur.
  
  
  
  Related Information:
  
  Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench) to manage DSOs and check their definitions.
  Database Tools: Use database tools or SQL queries to analyze the data directly in the underlying database.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common problems.
  Documentation: Refer to SAP documentation for best practices on managing DSOs and ensuring data integrity.
  
  By following these steps, you should be able to resolve the RS_DB_DB6548 error and ensure that your DSO is functioning correctly.
