• What is the cause and solution for SAP error message CNV_MBT_CWB034 - Object &1 is to be converted but does not use cluster technique ?

  The SAP error message CNV_MBT_CWB034 indicates that an object is set to be converted, but it does not utilize the cluster technique, which is often required for certain types of data migration or conversion processes in SAP systems. This error typically arises during data migration activities, especially when using the SAP S/4HANA Migration Cockpit or other data conversion tools.
  Cause:
  
  Non-Clustered Data Structure: The object in question is likely a table or data structure that is not designed to use the cluster technique. In SAP, clustered tables are used to store related data in a single physical table, which can improve performance and data integrity.
  Configuration Issues: There may be configuration settings in the migration tool or the source system that do not align with the requirements for using the cluster technique.
  Data Model Changes: If the data model has changed (for example, moving from an older version of SAP to S/4HANA), certain objects may no longer be compatible with the expected clustered format.
  
  Solution:
  
  Review Object Configuration: Check the configuration of the object that is causing the error. Ensure that it is set up correctly and that it is intended to use the cluster technique.
  Modify Data Structure: If possible, consider modifying the data structure to use a clustered format. This may involve changing the way data is stored or accessed.
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration or conversion process you are undertaking. There may be specific guidelines or prerequisites for the objects you are working with.
  Use Alternative Migration Methods: If the object cannot be converted using the cluster technique, consider using alternative methods for data migration that do not require clustering.
  Engage SAP Support: If the issue persists, consider reaching out to SAP support for assistance. They may provide insights or patches that can resolve the issue.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that address this specific error message or provide guidance on data migration and conversion processes.
  Migration Cockpit Documentation: Review the official SAP documentation for the Migration Cockpit, which may provide additional context on how to handle objects that do not use the cluster technique.
  Data Model Changes: Familiarize yourself with the changes in data models between different SAP versions, especially if migrating to S/4HANA, as this can impact how data is structured and converted.
  
  By addressing the underlying causes and following the suggested solutions, you should be able to resolve the CNV_MBT_CWB034 error and successfully complete your data migration or conversion process.
