• What is the cause and solution for SAP error message CNV_10996056 - Error &1 when writing table &2. ?

  The SAP error message CNV_10996056 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that there is an issue when trying to write data to a specific table in the database.
  Cause:
  The error message CNV_10996056 can be caused by several factors, including:
  
  
  Data Integrity Issues: The data being written may violate constraints or rules defined in the target table, such as primary key violations, foreign key constraints, or unique constraints.
  
  
  Data Type Mismatches: The data types of the fields in the source data may not match the expected data types in the target table.
  
  
  Missing Required Fields: Required fields in the target table may not be populated in the source data.
  
  
  Database Locking Issues: The target table may be locked by another process, preventing the write operation.
  
  
  Authorization Issues: The user executing the migration may not have the necessary permissions to write to the target table.
  
  
  Solution:
  To resolve the CNV_10996056 error, you can take the following steps:
  
  
  Check Data Integrity: Review the data being migrated to ensure it adheres to the constraints of the target table. Look for duplicate entries, null values in required fields, and ensure that foreign key relationships are maintained.
  
  
  Validate Data Types: Ensure that the data types in the source data match those expected in the target table. You may need to transform the data accordingly.
  
  
  Populate Required Fields: Make sure that all required fields in the target table are being populated with valid data.
  
  
  Check for Locks: Investigate if the target table is locked by another transaction. You can use transaction codes like SM12 to check for locks and SM21 for system logs.
  
  
  Review Authorizations: Ensure that the user executing the migration has the necessary authorizations to write to the target table. You may need to adjust roles and permissions.
  
  
  Consult Logs: Check the application logs (transaction SLG1) for more detailed error messages that can provide additional context about the failure.
  
  
  Test with Smaller Data Sets: If possible, try migrating a smaller subset of data to isolate the issue and identify specific records that may be causing the error.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide guidance on data migration issues.
