• What is the cause and solution for SAP error message RSL_UI202 - Same field name ?

  The SAP error message RSL_UI202, which indicates "Same field name," typically occurs in the context of SAP UI development, particularly when working with SAP Fiori applications or SAP UI5. This error arises when there are multiple fields in a UI component (like a form or a table) that have the same name or ID, which can lead to ambiguity in data binding and event handling.
  Cause:
  
  Duplicate Field Names: The most common cause of this error is having two or more fields in the same context (like a form or a view) that share the same name or ID.
  Incorrect XML or JSON Configuration: If you are defining your UI elements in XML or JSON, a typo or oversight can lead to duplicate identifiers.
  Dynamic Controls: If you are generating controls dynamically in your code, you might inadvertently create controls with the same ID.
  
  Solution:
  
  Check Field Names: Review the UI component where the error occurs and ensure that all field names or IDs are unique. This includes checking both static and dynamically generated fields.
  Modify IDs: If you find duplicate field names, modify them to ensure uniqueness. This can be done by appending a suffix or prefix to the IDs.
  Use Binding Contexts: If you are using data binding, ensure that the binding contexts are correctly set up to avoid conflicts.
  Debugging: Use debugging tools to trace the creation of UI elements and identify where duplicates might be occurring.
  Review XML/JSON Definitions: If you are using XML or JSON to define your UI, carefully review these files for any duplicate entries.
