  The SAP error message DPR_FIN_GECCO028, which states "System does not allow switch to manual assignment," typically occurs in the context of project management and resource allocation within the SAP system, particularly in the SAP Project System (PS) or SAP Portfolio and Project Management (PPM) modules.
  Cause:
  This error usually arises due to one of the following reasons:
  
  
  Project Settings: The project or task may be configured to disallow manual assignment of resources. This can be due to settings in the project definition or the work breakdown structure (WBS) element.
  
  
  Resource Assignment Mode: The system may be set to a specific mode of resource assignment (e.g., automatic assignment) that does not permit switching to manual assignment.
  
  
  Status of the Project: The project or task may be in a status that restricts changes to resource assignments. For example, if the project is already in a closed or completed status, manual changes may not be allowed.
  
  
  User Authorizations: The user may not have the necessary authorizations to change the assignment mode for the project or task.
  
  
  Solution:
  To resolve the error, consider the following steps:
  
  
  Check Project Settings:
  
  Navigate to the project or WBS element in question and review the settings related to resource assignment. Ensure that manual assignment is allowed.
  
  
  
  Change Assignment Mode:
  
  If the project is currently set to automatic assignment, check if you can change it to allow manual assignment. This may involve changing settings in the project management configuration.
  
  
  
  Review Project Status:
  
  Check the status of the project or task. If it is in a status that restricts changes, you may need to change the status back to a more flexible state (e.g., "In Progress") to allow for manual assignments.
  
  
  
  User Authorizations:
  
  Verify that you have the necessary authorizations to make changes to resource assignments. If not, contact your SAP security administrator to request the appropriate permissions.
