• What is the cause and solution for SAP error message FDT_CORE900 - &1 is unnamed and not used by any object ?

  The SAP error message FDT_CORE900 typically indicates that there is an issue with a field or object in the SAP system that is either unnamed or not associated with any existing object. This error is often encountered in the context of SAP Fiori or SAP UI5 applications, particularly when dealing with field definitions in the Fiori Design Time (FDT) framework.
  Cause:
  
  Unnamed Field: The error suggests that there is a field that has not been given a proper name or identifier, which is required for the system to recognize and utilize it.
  Unused Object: The field or object may not be linked to any active or relevant application or data model, making it redundant or orphaned.
  Configuration Issues: There may be issues in the configuration of the Fiori application or the underlying data model that lead to this error.
  Transport Issues: If the object was transported from one system to another, it may not have been properly configured or linked in the target system.

  Check Field Definitions: Review the field definitions in the Fiori application or the relevant data model. Ensure that all fields have proper names and are correctly defined.
  Link Objects: If the field is supposed to be used in a specific context, ensure that it is properly linked to the relevant object or application.
  Review Configuration: Go through the configuration settings of the Fiori application to ensure that all necessary components are correctly set up.
  Delete Unused Fields: If the field is truly not needed, consider removing it from the application or data model to avoid confusion.
  Transport Validation: If the issue arose after a transport, validate that all necessary objects were transported correctly and that there are no missing dependencies.
