• What is the cause and solution for SAP error message CNV_00001223 - In table &1 all fields are excluded or read-only; table ignored. ?

  The SAP error message CNV_00001223 indicates that during a data migration or conversion process, the system has encountered a situation where all fields in a specified table (&1) are either excluded from processing or marked as read-only. As a result, the table is ignored in the migration process.
  Cause:
  
  
  Field Exclusion: All fields in the specified table may have been explicitly excluded from the migration process. This can happen if the configuration settings for the migration do not allow for any data to be transferred from that table.
  
  
  Read-Only Fields: The fields in the table may be set to read-only status, meaning that they cannot be modified or populated during the migration process. This can occur if the table is part of a system that is locked or if the fields are defined in such a way that they cannot accept new data.
  
  
  Configuration Issues: There may be issues in the configuration of the migration tool or the specific migration project that lead to all fields being excluded or set to read-only.
  
  
  Solution:
  
  
  Check Configuration: Review the configuration settings for the migration project. Ensure that the fields in the specified table are not excluded from the migration process. This may involve checking the mapping and transformation rules.
  
  
  Field Properties: Investigate the properties of the fields in the table. If they are set to read-only, determine if this is intentional or if it can be changed. You may need to adjust the field definitions or the migration settings to allow for data to be written to these fields.
  
  
  Consult Documentation: Refer to the SAP documentation related to the specific migration tool you are using (e.g., SAP S/4HANA Migration Cockpit, SAP Data Services, etc.) for guidance on how to handle excluded or read-only fields.
  
  
  Testing: After making any changes, perform a test migration to ensure that the table is now being processed correctly and that data can be migrated as expected.
  
  
  Seek Support: If the issue persists, consider reaching out to SAP support or consulting with an SAP expert who can provide more tailored assistance based on your specific system configuration and migration scenario.
