• What is the cause and solution for SAP error message UI102 - Data model &1 already exists ?

  The SAP error message UI102, which states "Data model &1 already exists," typically occurs when you are trying to create a new data model in the SAP system, but a data model with the same name or identifier already exists in the system. This can happen in various contexts, such as when working with SAP Fiori, SAP UI5, or other SAP applications that utilize data models.
  Cause:
  
  Duplicate Data Model: The most common cause is that a data model with the same name or identifier already exists in the system.
  Incorrect Configuration: There may be a misconfiguration in the system that is causing the system to recognize an existing data model incorrectly.
  Development Environment Issues: If you are working in a development environment, it is possible that the data model was created in a different transport or package.
  
  Solution:
  
  
  Check Existing Data Models: 
  
  Use transaction codes like SE11 (Data Dictionary) or SE80 (Object Navigator) to check if a data model with the same name already exists.
  If it does exist and you do not need it, consider deleting or renaming it.
  
  
  
  Rename the New Data Model: 
  
  If you need to create a new data model, consider using a different name or identifier that does not conflict with existing models.
  
  
  
  Review Transport Requests: 
  
  If you are working in a development environment, check if the data model was transported from another system and is causing a conflict.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or notes related to the specific application or module you are working with to see if there are any known issues or additional steps required.
