• What is the cause and solution for SAP error message DPR_OBJ_LINK009 - No link allowed between object type '&1' (&2) and &3 ?

  The SAP error message DPR_OBJ_LINK009 indicates that there is an attempt to create a link between two objects that are not allowed to be linked in the context of SAP's Project Management (DPR - Dynamic Project Management). The message typically appears when you are trying to link incompatible object types, such as a task to a project or a project to a milestone, where the system does not permit such relationships.
  Cause:
  The error occurs due to one of the following reasons:
  
  Incompatible Object Types: The object types you are trying to link do not have a defined relationship in the system. For example, you might be trying to link a task to a project in a way that is not supported.
  Configuration Issues: The system configuration may not allow certain types of links between objects based on the project structure or settings.
  Incorrect Object Status: One of the objects may be in a status that does not allow linking (e.g., a completed task).
  
  Solution:
  To resolve the error, you can take the following steps:
  
  Check Object Types: Verify the object types you are trying to link. Ensure that they are compatible and that the link you are trying to create is allowed by the system.
  Review Project Structure: Look at the project structure and ensure that the objects are correctly defined and that their statuses allow for linking.
  Consult Documentation: Refer to SAP documentation or help resources to understand the allowed relationships between different object types in your specific version of SAP.
  Adjust Configuration: If necessary, consult with your SAP administrator or a functional consultant to adjust the configuration settings that govern object linking.
  Use Alternative Linking Methods: If direct linking is not allowed, consider using alternative methods to achieve the desired relationship, such as creating a higher-level object that can encompass both.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context.
  Transaction Codes: Familiarize yourself with transaction codes related to project management (e.g., CJ20N for project planning) to better navigate the system.
  User Roles and Permissions: Ensure that your user role has the necessary permissions to create links between the objects in question.
  
  If the issue persists after following these steps, it may be beneficial to reach out to SAP support or your internal SAP support team for further assistance.
