• What is the cause and solution for SAP error message CNV_20100383 - &1: read-only indicator was set ?

  The SAP error message CNV_20100383 with the description "read-only indicator was set" 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 the system is trying to modify data in a table or field that has been marked as read-only, which prevents any changes from being made.
  Cause:
  
  Read-Only Settings: The target table or field is set to read-only due to configuration settings or because it is part of a standard SAP table that should not be modified.
  Data Locking: The data might be locked by another process or transaction, preventing any changes.
  Incorrect Mapping: The mapping of fields during the migration process may be incorrect, leading to attempts to write to read-only fields.
  Authorization Issues: The user executing the migration may not have the necessary authorizations to modify certain fields or tables.
  
  Solution:
  
  Check Table Settings: Verify the settings of the target table or field to ensure it is not set to read-only. This can be done through transaction SE11 (Data Dictionary) or SE14 (Database Utility).
  Review Migration Mapping: Ensure that the mapping of fields in the migration tool is correct and that you are not trying to write to fields that should remain unchanged.
  Check for Locks: Use transaction SM12 to check for any locks on the data that might be preventing changes. If locks are found, they may need to be released.
  User Authorizations: Ensure that the user executing the migration has the necessary authorizations to modify the data in the target system.
  Consult Documentation: Review the SAP documentation related to the specific migration tool you are using for any additional configuration or prerequisites that may need to be addressed.
