• What is the cause and solution for SAP error message DDLS204 - CASE for column &/(&): non-supported data type & ?

  The SAP error message DDLS204 typically indicates that there is an issue with a data type in a database table or view definition. Specifically, the message states that a column is using a non-supported data type, which can occur during the creation or modification of database objects in the Data Dictionary (DDIC).
  Cause:
  The error can arise from several scenarios:
  
  Unsupported Data Type: The column in question is defined with a data type that is not supported by the underlying database system. This can happen if you are using a data type that is specific to a certain database but not recognized by the one you are currently using.
  Database Compatibility: If you are working with a database that has specific limitations or does not support certain data types (e.g., using a data type that is available in HANA but not in Oracle).
  Incorrect Data Type Mapping: When migrating or upgrading systems, there may be discrepancies in how data types are mapped between different database systems.
  
  Solution:
  To resolve the DDLS204 error, you can take the following steps:
  
  
  Check Data Type Compatibility:
  
  Review the data type of the column that is causing the error. Ensure that it is compatible with the database you are using.
  Refer to the SAP documentation for the specific database to see which data types are supported.
  
  
  
  Modify the Data Type:
  
  If the data type is indeed unsupported, you will need to change it to a supported type. This can be done in the Data Dictionary (SE11) by editing the table or view definition.
  Choose a data type that is compatible with your database and meets your application requirements.
  
  
  
  Re-Generate Database Objects:
  
  After making changes to the data type, you may need to regenerate the database objects. This can be done using transaction SE11 or SE14 (for database utility).
  
  
  
  Check for Dependencies:
  
  Ensure that there are no dependent objects (like views, indexes, or foreign keys) that might be affected by the change in data type. You may need to adjust these as well.
  
  
  
  Test Changes:
  
  After making the necessary changes, test the application to ensure that everything is functioning as expected and that the error no longer occurs.
