• What is the cause and solution for SAP error message DDLS120 - & & is defined in multiple DDL sources (&) ?

  The SAP error message DDLS120 indicates that a particular object (like a table, view, or other database object) is defined in multiple Data Definition Language (DDL) sources. This typically occurs when there are conflicting definitions for the same object in different DDL sources, which can lead to ambiguity in the system.
  Cause:
  
  
  Multiple Definitions: The same object is defined in more than one DDL source, which can happen if:
  
  There are multiple transport requests that contain the same object.
  Different development environments have conflicting definitions.
  Manual changes were made to the DDL sources without proper synchronization.
  
  
  
  Transport Issues: If objects are transported from one system to another (e.g., from development to production), and the same object exists in both systems with different definitions, this error can occur.
  
  
  Namespace Conflicts: If the object is defined in different namespaces or packages, it can lead to conflicts.
  
  
  Solution:
  
  
  Identify Conflicting Definitions: Use transaction codes like SE11 (Data Dictionary) or SE80 (Object Navigator) to check the definitions of the object in question. Look for the object in different packages or namespaces.
  
  
  Remove Duplicates: Once you identify the conflicting definitions, you need to decide which definition to keep. You may need to:
  
  Delete or modify the duplicate definitions.
  Ensure that only one version of the object exists in the system.
  
  
  
  Transport Management: If the issue arises from transport requests, ensure that the transport requests are properly managed. You may need to:
  
  Adjust the transport sequence.
  Re-import the correct version of the object.
  
  
  
  Check for Active Versions: Ensure that there are no active versions of the object in different states. You can use transaction SE03 (Transport Organizer Tools) to analyze the transport logs.
  
  
  Consistency Check: After resolving the conflicts, perform a consistency check to ensure that the definitions are now aligned and that there are no further issues.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SE11 (Data Dictionary), SE80 (Object Navigator), SE03 (Transport Organizer), and SE37 (Function Module).
  Documentation: Review SAP documentation or notes related to DDL sources and object definitions for best practices.
  SAP Notes: Check for any SAP Notes that might address specific issues related to DDLS120 or similar errors.
  
  By following these steps, you should be able to resolve the DDLS120 error and ensure that your DDL sources are correctly defined without conflicts.
