• What is the cause and solution for SAP error message CNV_20700048 - For material class &1, multi-object classification is active ?

  The SAP error message CNV_20700048 indicates that multi-object classification is active for a specific material class, which can lead to issues during data migration or processing in SAP systems. This error typically arises in the context of data conversion or migration projects, particularly when using the SAP S/4HANA Migration Cockpit or similar tools.
  Cause:
  The error occurs because the material class specified in the error message has multi-object classification enabled. This means that the system expects certain data structures or configurations that are not being met during the operation you are trying to perform.
