• What is the cause and solution for SAP error message SDDIC_ADT_SRVD003 - Multiple entities with same name '&1' not allowed ?

  The SAP error message SDDIC_ADT_SRVD003 indicates that there are multiple entities (such as tables, views, or other database objects) with the same name in the same context, which is not allowed in the SAP system. This error typically occurs when you are trying to create or activate an object in the ABAP Development Tools (ADT) or when working with the Data Dictionary.
  Cause:
  
  Duplicate Names: The most common cause of this error is that there are two or more objects (like tables, views, or structures) with the same name in the same package or namespace.
  Transport Issues: Sometimes, if objects are transported from one system to another, duplicates may inadvertently be created.
  Development Environment: If multiple developers are working on the same object or if there are conflicting changes in the development environment, this can lead to naming conflicts.
  
  Solution:
  
  
  Identify Duplicates: 
  
  Use transaction codes like SE11 (Data Dictionary) or SE80 (Object Navigator) to search for the object name in question. Check if there are multiple entries for the same name.
  You can also use the ABAP report RS_ABAP_SOURCE_SCAN to find duplicate names in your development environment.
  
  
  
  Rename or Delete: 
  
  If you find duplicates, you can either rename the conflicting objects or delete the unnecessary ones. Ensure that you have the necessary authorizations to make these changes.
  If the duplicates are in different packages, consider moving them to avoid conflicts.
  
  
  
  Check Transport Requests: 
  
  If the issue arose after a transport, check the transport requests to ensure that no duplicates were introduced during the transport process.
  
  
  
  Consult Documentation: 
  
  Review the SAP documentation or notes related to the specific error message for any additional guidance or updates.
  
  
  
  Re-activate Objects: 
  
  After resolving the duplicates, try to re-activate the object that was causing the error.
  
  
  
  Related Information:
  
  Namespace Management: Ensure that your development objects are properly organized within namespaces to avoid naming conflicts.
  Naming Conventions: Follow SAP's naming conventions and guidelines to minimize the risk of duplicate names.
  Version Control: Use version control systems to manage changes and avoid conflicts when multiple developers are working on the same objects.
