• What is the cause and solution for SAP error message /UI2/FDM_PB_CHIP_XML109 - Property '&1' is declared twice ?

  The SAP error message /UI2/FDM_PB_CHIP_XML109 Property '&1' is declared twice typically occurs in the context of SAP UI5 or Fiori applications when there is a duplicate declaration of a property in a UI5 XML view or component. This can happen when the same property name is defined more than once in the same context, leading to ambiguity in property resolution.
  Cause:
  
  Duplicate Property Declaration: The most common cause is that a property is defined multiple times in the same XML view or component configuration.
  Inheritance Issues: If a component inherits properties from a parent component, and the same property is declared in both the parent and child, this can lead to conflicts.
  Typographical Errors: Sometimes, a simple typo can lead to the same property being declared in a way that the framework interprets as a duplicate.
  
  Solution:
  
  Check XML View/Component: Review the XML view or component where the error is occurring. Look for any properties that are declared more than once. Remove or rename the duplicate property.
  Review Inheritance: If you are using inheritance, ensure that properties are not being declared in both the parent and child components unless intended. If they are, consider whether you need to override the property or simply use the inherited one.
  Use Unique Names: Ensure that all property names are unique within the same context to avoid conflicts.
  Debugging: If the error is not immediately apparent, use debugging tools or logs to trace where the property is being declared and identify the duplicates.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP UI5 documentation for guidelines on property declarations and best practices.
  SAP Community: Engage with the SAP Community forums for insights from other developers who may have encountered similar issues.
  Version Compatibility: Ensure that you are using compatible versions of SAP UI5/Fiori, as certain versions may have specific requirements or bugs related to property declarations.
  
  By following these steps, you should be able to resolve the error and ensure that your SAP UI5/Fiori application functions correctly.
