• What is the cause and solution for SAP error message DMU081 - Error inserting table &1: &3 out of &2 records updated ?

  The SAP error message DMU081 typically occurs during data migration or data transfer processes, particularly when using the Data Migration Workbench (DMW) or similar tools. The error message indicates that there was an issue inserting records into a specified table, where the number of records updated exceeds the expected limit.
  Cause:
  The error message DMU081 can be caused by several factors, including:
  
  Data Volume Exceeded: The number of records being processed exceeds the maximum limit allowed for a single transaction or batch.
  Database Constraints: There may be constraints on the database table (such as primary key, foreign key, or unique constraints) that are being violated by the incoming data.
  Data Format Issues: The data being inserted may not conform to the expected format or data types defined in the target table.
  Locking Issues: The table may be locked by another transaction, preventing the insertion of new records.
  Insufficient Authorizations: The user executing the operation may not have the necessary authorizations to perform the insert operation.
  
  Solution:
  To resolve the DMU081 error, you can take the following steps:
  
  Check Data Volume: Review the number of records being processed and ensure it does not exceed the limits set by the system. If necessary, split the data into smaller batches.
  Review Constraints: Check the target table for any constraints that may be causing the insert to fail. Ensure that the incoming data adheres to these constraints.
  Validate Data Format: Ensure that the data being inserted matches the expected data types and formats for each field in the target table.
  Check for Locks: Use transaction codes like SM12 to check for any locks on the table. If locks are found, you may need to wait for the other transaction to complete or resolve the locking issue.
  Authorization Check: Verify that the user has the necessary authorizations to perform the insert operation. You may need to consult with your SAP security team if there are authorization issues.
  Error Logs: Check the application logs (transaction SLG1) for more detailed error messages that may provide additional context on the failure.
  
  Related Information:
