  The SAP error message R9E059 indicates that there is a duplication of technical names in the system. This typically occurs when two or more objects (like tables, fields, or other entities) are assigned the same technical name, which is not allowed in SAP.
  Cause:
  
  Duplicate Technical Names: The most common cause of this error is that two objects are trying to use the same technical name. This can happen during the creation of new objects or when transporting objects from one system to another.
  Transport Issues: If objects are transported from a development environment to a production environment, and there are naming conflicts, this error can occur.
  Custom Development: In custom development scenarios, developers might inadvertently create objects with the same technical name.
  
  Solution:
  
  Identify Duplicates: Use transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), or SE37 (Function Module) to search for the objects with the conflicting technical names. You can also use the table TADIR to check for existing objects.
  Rename Objects: Once you identify the duplicates, you will need to rename one of the objects to ensure that all technical names are unique. This can involve changing the name of a table, field, or other object types.
  Check Transport Requests: If the issue arises from a transport request, check the transport logs and ensure that the objects being transported do not conflict with existing objects in the target system.
  Consistency Check: After making changes, perform a consistency check to ensure that there are no further conflicts. You can use transaction code SE14 (Database Utility) to check for inconsistencies in database objects.
  Re-transport: If the issue was caused by a transport, you may need to re-transport the objects after resolving the naming conflict.
