  The SAP error message CNVMBTSCRAMBLE023 typically occurs in the context of data migration or transformation processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that you are trying to edit a primary field in a line that is not allowed to be modified.

  Data Migration Restrictions: During data migration processes, certain fields may be locked to prevent changes that could lead to data integrity issues.

  Review the Data Structure: Check the data structure you are working with to identify which fields are designated as primary keys. Ensure that you are not attempting to modify these fields.
  Adjust Your Input Data: If you need to change a primary key value, you may need to delete the existing record and create a new one with the desired key value, if the business logic allows for it.
  Consult Documentation: Refer to the SAP documentation or migration guides for specific instructions on handling primary key fields during data migration.
  Use the Correct Migration Tools: Ensure you are using the appropriate tools and methods for data migration that respect the constraints of the target system.
