• What is the cause and solution for SAP error message /UI5/APP_API145 - Indexing of SAPUI5 repository &1 rejected because of duplicate id ?

  The SAP error message /UI5/APP_API145 Indexing of SAPUI5 repository &1 rejected because of duplicate id indicates that there is a problem with duplicate IDs in the SAPUI5 application repository. This typically occurs when there are multiple components or resources in your SAPUI5 application that have the same ID, which violates the uniqueness requirement for IDs in the SAPUI5 framework.
  Cause:
  
  
  Duplicate IDs: The most common cause of this error is that two or more UI5 components, views, or controls are defined with the same ID. This can happen if:
  
  You have copied and pasted code without changing the IDs.
  You are dynamically generating IDs but not ensuring their uniqueness.
  There are multiple versions of the same component or library loaded.
  
  
  
  Incorrect Configuration: Sometimes, the configuration of the application might lead to the same ID being generated for different components.
  
  
  Solution:
  
  
  Identify Duplicate IDs: 
  
  Review your application code to find where IDs are defined. Look for any hardcoded IDs or dynamically generated IDs that might conflict.
  Use tools like the browser's developer console to inspect the rendered HTML and identify duplicate IDs.
  
  
  
  Modify IDs: 
  
  Change the IDs of the conflicting components to ensure they are unique. This can be done by appending a suffix or prefix to the IDs or by using a unique identifier from your data model.
  
  
  
  Dynamic ID Generation: 
  
  If you are generating IDs dynamically, ensure that the logic used to create these IDs guarantees uniqueness. You can use a combination of the component name and a unique identifier (like a timestamp or a counter).
  
  
  
  Check for Libraries: 
  
  If you are using third-party libraries or components, ensure that they do not introduce duplicate IDs. If they do, consider modifying them or using alternative libraries.
  
  
  
  Re-index the Application: 
  
  After resolving the duplicate ID issues, re-index the SAPUI5 application to ensure that the changes are recognized by the system.
  
  
  
  Related Information:
  
  SAPUI5 Documentation: Refer to the official SAPUI5 documentation for best practices on ID management and component creation.
  Debugging Tools: Use browser developer tools to inspect the DOM and identify duplicate IDs.
  SAP Community: Engage with the SAP Community forums for additional insights and solutions from other developers who may have faced similar issues.
  
  By addressing the duplicate ID issue, you should be able to resolve the error and successfully index your SAPUI5 application.
