• What is the cause and solution for SAP error message TR_AUSL591 - Object from another namespace (&1 instead of &2): ?

  The SAP error message TR_AUSL591 indicates that there is an issue with the transport of an object that belongs to a different namespace than expected. This typically occurs when you are trying to transport an object (like a program, function module, or class) that is defined in a different namespace than the one you are currently working in.
  Cause:
  
  Namespace Mismatch: The object you are trying to transport is in a different namespace than the one specified in the transport request. For example, if you are working in a custom namespace (like Z or Y) and the object belongs to a standard namespace (like SAP's own namespaces), this error can occur.
  Transport Request Configuration: The transport request may not be configured correctly to include objects from different namespaces.
  Development Class Issues: The object might be assigned to a development class that is not allowed to transport objects from other namespaces.
  
  Solution:
  
  Check Object Namespace: Verify the namespace of the object you are trying to transport. You can do this by checking the properties of the object in the ABAP Workbench (SE80 or SE11).
  Adjust Transport Request: If the object is indeed in a different namespace, you may need to create a new transport request that is appropriate for that namespace or adjust the existing transport request to include the correct namespace.
  Use Correct Development Class: Ensure that the object is assigned to the correct development class that allows for the transport of objects from the desired namespace.
  Consult with Basis Team: If you are unsure about how to proceed, it may be helpful to consult with your SAP Basis team or system administrator, as they can provide guidance on transport configurations and namespace policies.
  
  Related Information:
  
  Namespaces in SAP: SAP uses namespaces to organize objects and avoid naming conflicts. Custom development typically occurs in Z or Y namespaces, while standard SAP objects reside in other namespaces.
  Transport Management System (TMS): Understanding how the TMS works can help in managing transport requests and resolving issues related to object transport.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context or solutions.
  
  By following these steps, you should be able to resolve the TR_AUSL591 error and successfully transport your objects.
