• What is the cause and solution for SAP error message DDLS804 - Namespace of DDL '&1' does not match namespace of VIEWNAME '&2' ?

  The SAP error message DDLS804 indicates a namespace mismatch between a Data Definition Language (DDL) object and a view in the SAP system. This typically occurs when you are trying to create or modify a database object (like a view) that is expected to belong to a specific namespace, but the object you are working with is in a different namespace.
  Cause:
  
  Namespace Mismatch: The DDL object (e.g., a view) is defined in a different namespace than what is expected. In SAP, namespaces are used to organize objects and prevent naming conflicts.
  Incorrect Object Reference: The DDL statement may be referencing an object that is not in the correct namespace.
  Transport Issues: If the object was transported from one system to another, it may not have been properly assigned to the correct namespace.
  
  Solution:
  
  Check Namespaces: Verify the namespaces of both the DDL object and the view. Ensure that they match. You can do this by checking the object properties in the ABAP Dictionary (transaction SE11).
  Modify DDL Statement: If you are creating or modifying the DDL, ensure that you are using the correct namespace. Adjust the DDL statement to reference the correct view or object.
  Recreate Object: If the object is incorrectly defined, you may need to drop and recreate it in the correct namespace.
  Transport Request: If the issue arose due to a transport, check the transport request to ensure that the objects are correctly assigned to the appropriate namespace.
  Consult Documentation: Review SAP documentation or notes related to namespaces and DDL objects for any specific guidelines or best practices.
  
  Related Information:
  
  Namespaces in SAP: SAP uses namespaces to categorize objects. Custom objects typically reside in a customer namespace (e.g., Z or Y), while standard SAP objects reside in the SAP namespace.
  ABAP Dictionary: Use transaction SE11 to view and manage database objects, including tables, views, and data elements.
  Transport Management System (TMS): Use transaction STMS to manage transports and ensure that objects are correctly transported between systems.
