CNV_MBT333 - Details

• The SAP error message CNV_MBT333: Document already exists typically occurs during data migration or data transfer processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that the system is attempting to create a document (such as a financial document, material document, etc.) that already exists in the target system.
  Causes:
  
  Duplicate Data: The most common cause is that the data being migrated contains duplicates, meaning that the same document is being attempted to be created more than once.
  Incorrect Mapping: There may be issues with the mapping of source data to target fields, leading to conflicts.
  Previous Migration Attempts: If a previous migration attempt was partially successful, it may have left behind documents that are now causing conflicts.
  Data Integrity Issues: There may be issues with the integrity of the data being migrated, such as missing keys or references.
  
  Solutions:
  
  Check for Duplicates: Review the source data for duplicates.
