• What is the cause and solution for SAP error message CNV_IUUC_REPL_ADV_SE221 - The 'LIKE' operator can only be used with character-like data types ?

  The SAP error message CNV_IUUC_REPL_ADV_SE221 indicates that there is an issue with the use of the LIKE operator in a SQL statement or a data transformation process. This error specifically states that the LIKE operator can only be used with character-like data types, meaning that it cannot be applied to numeric or other non-character data types.
  Cause:
  
  Data Type Mismatch: The most common cause of this error is that the SQL query or transformation logic is attempting to use the LIKE operator on a field that is not of a character-like data type (e.g., VARCHAR, CHAR, etc.). This could happen if the field is of type INTEGER, FLOAT, or any other non-character type.
  Incorrect Field Mapping: In data replication or transformation scenarios, there might be a mapping issue where a non-character field is being compared using LIKE.
  Data Model Issues: If the underlying data model has changed (e.g., a field type was altered), it could lead to this error if the logic has not been updated accordingly.
  
  Solution:
  
  Check Data Types: Review the SQL query or the transformation logic to ensure that the LIKE operator is only being used with character-like data types. If you find a non-character field being used, you will need to modify the logic.
  Modify the Query: If you need to perform a pattern match on a non-character field, consider converting the field to a character type using a function like CAST or CONVERT (if supported by your database).
  SELECT * FROM your_table WHERE CAST(your_numeric_field AS VARCHAR) LIKE 'pattern%'
  
  Update Field Mapping: If this error occurs during data replication or transformation, check the field mappings in your configuration. Ensure that the fields being compared or filtered are of compatible types.
  Consult Documentation: Review the SAP documentation or notes related to the specific transaction or process you are working with to see if there are any known issues or updates regarding this error.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context.
  Data Replication: If this error occurs during data replication, ensure that the source and target data structures are aligned and that the data types are compatible.
  Testing: After making changes, test the query or transformation to ensure that the error is resolved and that the expected results are returned.
  
  By addressing the data type issue and ensuring that the LIKE operator is used correctly, you should be able to resolve the CNV_IUUC_REPL_ADV_SE221 error.
