• What is the cause and solution for SAP error message FDT_CORE490 - Data objects that are part of a bound data structure cannot be renamed ?

  The SAP error message FDT_CORE490 indicates that there is an attempt to rename a data object that is part of a bound data structure in the SAP system. This error typically occurs in the context of SAP Fiori or SAP UI5 applications, where data binding is used to connect UI elements to data models.
  Cause:
  The error arises when you try to rename a data object (like a field or property) that is already bound to a data structure. In SAP, bound data structures are those that have a defined relationship with other data objects, and renaming them can lead to inconsistencies or break the binding logic.

  Identify the Bound Data Structure: Determine which data structure the object belongs to. You can do this by checking the data model or the binding context in your application.
  
  
  Check for Dependencies: Look for any dependencies or references to the data object you are trying to rename. This includes checking for any UI elements, controllers, or other data models that may be using this object.
  
  
  Rename Carefully: If you still need to rename the data object, you should:
  
  Unbind the data object from any UI elements or data models.
  Rename the data object.
  Re-establish the bindings to the new name.
  
  
  
  Update References: After renaming, ensure that all references to the old name are updated to the new name throughout your application.
  
  
  Test the Application: After making changes, thoroughly test the application to ensure that everything works as expected and that there are no broken bindings or references.
