• What is the cause and solution for SAP error message WER030 - Element name &1 of the same type already exists ?

  The SAP error message:
  WER030: Element name &1 of the same type already exists
  
  Cause:
  This error occurs when you try to create or insert an element (such as a field, structure, table, or any other repository object) with a name that already exists in the same namespace or context and is of the same type. SAP enforces unique names for elements of the same type within a given scope to avoid conflicts and ambiguity.
  For example:
  
  Trying to create a data element or domain with a name that already exists.
  Adding a field to a structure or table where a field with the same name already exists.
  Creating a function module, program, or object with a name that is already taken.
  
  
  Solution:
  
  
  Check for existing elements:
  
  Use transaction SE11 (Data Dictionary) or SE80 (Object Navigator) to search for the element name you want to create.
  Verify if an element with the same name and type already exists.
  
  
  
  Rename the new element:
  
  Choose a unique name for the new element that does not conflict with existing ones.
  Follow your organization's naming conventions to avoid future conflicts.
  
  
  
  If you intended to modify an existing element:
  
  Instead of creating a new element, open the existing one and make the necessary changes.
  
  
  
  Check the namespace:
  
  Ensure you are working in the correct package or namespace.
  Sometimes, elements with the same name can exist in different namespaces, but within the same namespace, names must be unique.
