• What is the cause and solution for SAP error message CUMTX286 - Table & contains at least two lines (line no. &) with the same values ?

  The SAP error message CUMTX286 indicates that a specific table contains at least two lines (or entries) with the same values for a particular field or set of fields that are expected to be unique. This typically occurs in scenarios where data integrity is enforced, such as when trying to create or update records in a database table that has a unique constraint.
  Cause:
  
  
  Duplicate Entries: The most common cause of this error is that there are duplicate entries in the table for the specified field(s). This can happen due to:
  
  Incorrect data entry.
  Data import processes that do not check for existing records.
  Issues in data migration or synchronization processes.
  
  
  
  Unique Constraints: The table may have a unique constraint defined on one or more fields, and the system is trying to insert or update a record that would violate this constraint.
  
  
  Solution:
  
  
  Identify Duplicates: 
  
  Use SQL queries or SAP transaction codes (like SE16 or SE11) to check the table for duplicate entries. You can group by the relevant fields to find duplicates.
  Example SQL query:
  SELECT field1, field2, COUNT(*)
  FROM your_table
  GROUP BY field1, field2
  HAVING COUNT(*) > 1;
  
  
  
  
  Remove or Update Duplicates: 
  
  Once you identify the duplicate entries, you can either delete the duplicates or update them to ensure that each entry is unique.
  Ensure that you have a backup of the data before making any deletions or updates.
  
  
  
  Check Data Entry Processes: 
  
  Review the processes that lead to data entry in the table to ensure that they include checks for existing records to prevent duplicates in the future.
  
  
  
  Adjust Unique Constraints: 
  
  If the business logic allows for duplicates in certain scenarios, you may need to reconsider the unique constraints on the table. However, this should be done with caution and a clear understanding of the implications.
