• What is the cause and solution for SAP error message FDT_CORE161 - Maximum length of 255 is exceeded ?

  The SAP error message FDT_CORE161: Maximum length of 255 is exceeded typically occurs in the context of SAP Fiori or SAP UI5 applications, particularly when dealing with field lengths in data models or when binding data to UI elements. This error indicates that a string or data field exceeds the maximum allowed length of 255 characters.
  Cause:
  
  Data Model Definition: The data model may have a field defined with a maximum length of 255 characters, but the actual data being processed exceeds this limit.
  UI Element Binding: When binding data to UI elements, if the data being bound exceeds the defined length in the model, this error can occur.
  Database Constraints: If the underlying database table has a field with a length restriction, and the application tries to insert or update a record with a longer string, this error may arise.
  
  Solution:
  
  Check Data Length: Review the data being processed to ensure that it does not exceed the 255-character limit. You may need to truncate or modify the data before processing.
  Adjust Data Model: If the application requires longer strings, consider adjusting the data model to allow for longer lengths. This may involve changing the field definition in the OData service or the underlying database schema.
  Modify UI Bindings: Ensure that the UI elements are correctly bound to the data model and that the data being passed does not exceed the defined limits.
  Error Handling: Implement error handling in your application to catch this error and provide user-friendly feedback or logging for further analysis.
