  The SAP error message CNV_20000204 typically occurs during data deletion processes, particularly in the context of data migration or data cleansing activities. This error is often associated with the SAP Data Migration Cockpit or similar tools used for data transfer and transformation.
  Cause:
  The error message CNV_20000204 usually indicates that there is an issue with the deletion of data in a specific table. Common causes include:
  
  
  Foreign Key Constraints: The data you are trying to delete may be linked to other tables through foreign key relationships. If there are dependent records in other tables, the deletion will fail.
  
  
  Authorization Issues: The user executing the deletion may not have the necessary authorizations to delete records from the specified table.
  
  
  Data Locking: The records you are trying to delete may be locked by another process or user, preventing the deletion.
  
  
  Custom Logic or Enhancements: Custom code or enhancements in the system may be preventing the deletion of certain records.
  
  
  Data Integrity Issues: There may be data integrity issues that prevent the deletion of records, such as invalid data states.
  
  
  Solution:
  To resolve the CNV_20000204 error, you can take the following steps:
  
  
  Check Foreign Key Constraints: Review the table structure and identify any foreign key constraints. Ensure that there are no dependent records in related tables. You may need to delete or update those records first.
  
  
  Review Authorizations: Ensure that the user has the necessary authorizations to perform the deletion. You may need to consult with your SAP security team to verify and adjust user roles.
  
  
  Check for Locks: Use transaction codes like SM12 to check for any locks on the records you are trying to delete. If locks are found, you may need to wait for the locking process to complete or resolve the locking issue.
  
  
  Debug Custom Logic: If there are custom enhancements or logic in place, review the code to ensure that it is not inadvertently preventing the deletion of records.
  
  
  Data Integrity Checks: Perform data integrity checks to ensure that the data is in a valid state for deletion. You may need to clean up or correct any data issues before proceeding.
  
  
  Use Transaction Codes: If applicable, use transaction codes like SE11 (Data Dictionary) to analyze the table structure and constraints, or SE37 to check for function modules that may be involved in the deletion process.
