• What is the cause and solution for SAP error message DT571 - Full-text index &-&: & and data type RAWSTRING cannot be combined ?

  The SAP error message DT571 indicates that there is an issue with the combination of data types in a full-text index. Specifically, it suggests that the data type RAWSTRING cannot be used in conjunction with the full-text index. This error typically arises when you are trying to create or modify a full-text index on a database table that includes a field of type RAWSTRING.
  Cause:
  
  Data Type Incompatibility: The RAWSTRING data type is not supported for full-text indexing. Full-text indexes are designed to work with character-based data types (like CHAR, VARCHAR, TEXT, etc.) that can be tokenized and searched effectively.
  Index Definition: The definition of the full-text index may include fields that are not compatible with full-text search capabilities.
  
  Solution:
  
  Change Data Type: If possible, consider changing the data type of the field from RAWSTRING to a compatible character type (e.g., VARCHAR, TEXT). This may involve altering the database schema and ensuring that the data can be converted appropriately.
  Modify Full-Text Index: If changing the data type is not feasible, you may need to modify the full-text index definition to exclude the RAWSTRING field. Ensure that only compatible fields are included in the full-text index.
  Review Index Requirements: Reassess the requirements for full-text search in your application. If the RAWSTRING field is essential for your search functionality, consider alternative approaches, such as using a different indexing strategy or storing the data in a different format.
  
  Related Information:
  
  SAP Documentation: Refer to the SAP Help Portal or the specific documentation for your version of SAP to understand the limitations and requirements for full-text indexing.
  Database Compatibility: Check the compatibility of the database you are using with SAP, as different databases may have different rules regarding data types and indexing.
  Testing: After making changes, thoroughly test the full-text search functionality to ensure that it meets your application's requirements.
  
  If you continue to encounter issues or if the solution requires more complex changes, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.
