• What is the cause and solution for SAP error message /SCWM/MIGRATION_CUST308 - ERP record &1 in table T346L without counting '***' values, exists 2x ?

  The SAP error message /SCWM/MIGRATION_CUST308 indicates that there is a duplicate entry in the table T346L for a specific ERP record. This error typically arises during the migration or data transfer processes, particularly when working with the Extended Warehouse Management (EWM) module in SAP.
  Cause:
  The error occurs because the system has detected that the same record (identified by the key &1) exists more than once in the T346L table, excluding the entries that have '***' values. This can happen due to:
  
  Data Migration Issues: During data migration, if the same record is imported multiple times without proper checks, it can lead to duplicates.
  Configuration Errors: Incorrect configuration settings or manual entries in the system can also lead to duplicate records.
  Inconsistent Data: If data was manually entered or modified in a way that violates the uniqueness constraints of the table.
  
  Solution:
  To resolve this issue, you can follow these steps:
  
  
  Identify Duplicates:
  
  Use a SQL query or transaction code (like SE16 or SE11) to check the T346L table for the specific record. You can filter out the '***' values to focus on the relevant duplicates.
  Example SQL query:
  SELECT * FROM T346L WHERE <your_key_field> = '&1' AND <your_other_conditions>;
  
  
  
  
  Analyze the Data:
  
  Review the duplicate entries to understand why they exist. Check the fields that are supposed to be unique and see if there are any discrepancies.
  
  
  
  Remove or Merge Duplicates:
  
  Depending on your analysis, you may need to delete the duplicate entries or merge them if they contain different data that needs to be preserved.
  Ensure that you have a backup of the data before making any deletions or modifications.
  
  
  
  Check Migration Process:
  
  If this error occurred during a migration process, review the migration scripts or tools used to ensure they are correctly handling duplicates.
  Implement checks in the migration process to prevent duplicates from being created in the future.
