How To Fix RSCV588 - DB2/UDB: The representative primary index &1 is not unique.

SAP Error Message - Details

• Message type: E = Error

• Message class: RSCV - Analysis of BW objects (InfoCubes...)

• Message number: 588

• Message text: DB2/UDB: The representative primary index &1 is not unique.

What causes this issue?

Index &V1& is not unique as required.
A possible cause is the availability of data records with the same key
values in fact table &V2& for the time of the creation of the index.

System Response

Data records having the same key values after compression or after
rolling-up data is an inconsistency of data. This can lead to incorrect
reporting.

How to fix this error?

Check whether duplicate data records occur in the table and delete
these. Proceed as described in SAP Note 481450.
If duplicate data records no longer occur in the table, you can correct
the index in which you execute the action "Repair Indexes (Now)". You
can also activate the InfoCube in the background processing in
transaction RSDCUBE in "InfoCube Utilities" (recommended for very large
fact tables and when the timeout for foreground actions is exceeded
with "Repair Indexes (Now)".
Note that index &V1& needs to be deleted and recreated with each
repair. With large fact tables, this can lead to long run times. If
duplicate data records still occur in the table, the index is recreated
as not being unique.

  The SAP error message RSCV588 indicates that there is an issue with the primary index in a DB2/UDB database. Specifically, it states that the representative primary index is not unique, which means that there are duplicate values in the column(s) that are supposed to be unique.
  Cause:
  
  Duplicate Data: The most common cause of this error is that the data in the table has duplicates in the column(s) that are defined as the primary key or unique index.
  Incorrect Index Definition: The primary index may have been defined incorrectly, leading to a situation where it does not enforce uniqueness as expected.
  Data Migration Issues: If data was migrated from another system or imported, it may have introduced duplicates that violate the uniqueness constraint.
  
  Solution:
  
  
  Identify Duplicates: 
  
  Run a SQL query to identify the duplicate entries in the table. For example:
  SELECT column_name, COUNT(*)
  FROM table_name
  GROUP BY column_name
  HAVING COUNT(*) > 1;
  
  Replace column_name and table_name with the actual names used in your database.
  
  
  
  Resolve Duplicates: 
  
  Once you have identified the duplicates, you will need to decide how to handle them. Options include:
  
  Deleting duplicate records.
  Merging records if they contain complementary information.
  Modifying the data to ensure uniqueness.
  
  
  
  
  
  Check Index Definition: 
  
  Review the definition of the primary index to ensure it is set up correctly. You may need to drop and recreate the index if it is not defined properly.
  
  
  
  Rebuild Index: 
  
  After resolving duplicates, you may need to rebuild the index to ensure it reflects the current state of the data.
  
  
  
  Data Validation:
