• What is the cause and solution for SAP error message CNV_OR_PE_GEN004 - Table &1 already has data; adjustment is not possible ?

  The SAP error message CNV_OR_PE_GEN004 indicates that a specific table (denoted as &1) already contains data, which prevents the adjustment or operation you are trying to perform. This error typically arises during data migration or conversion processes, particularly when using SAP's Conversion Tools or during the execution of certain programs that modify or adjust data in specific tables.
  Cause:
  
  Existing Data: The primary cause of this error is that the target table already has data in it, which conflicts with the operation you are trying to perform (e.g., inserting or adjusting data).
  Incorrect Sequence of Operations: The operation may be executed in the wrong sequence, where the table should be empty before the adjustment.
  Configuration Issues: There may be configuration settings that are not aligned with the expected state of the database.
  
  Solution:
  
  Check Table Contents: Verify the contents of the table specified in the error message. If it contains data that should not be there, you may need to clear it out or adjust your migration strategy.
  Data Deletion: If appropriate, you can delete the existing data in the table before running the adjustment. Be cautious with this approach, as it may lead to data loss.
  
  Use transaction codes like SE14 (Database Utility) or SE11 (Data Dictionary) to manage the data.
  
  
  Adjust Migration Steps: Review the migration or conversion steps to ensure that they are executed in the correct order. Ensure that any prerequisites for the operation are met.
  Consult Documentation: Refer to the SAP documentation related to the specific migration or conversion tool you are using. There may be specific guidelines or prerequisites that need to be followed.
