• What is the cause and solution for SAP error message PEP111 - The selected function cannot be used for this task type ?

  The SAP error message PEP111, which states "The selected function cannot be used for this task type," typically occurs in the context of Project System (PS) or Project Management (PM) modules when a user attempts to perform an action that is not compatible with the current task type or project structure.
  Cause:
  
  Incompatible Functionality: The function you are trying to use (e.g., assigning resources, changing status, etc.) is not applicable to the specific task type you are working with. For example, certain functions may only be available for specific types of tasks (like internal or external tasks).
  Task Type Restrictions: The task type may have restrictions based on its configuration or the project structure. For instance, if the task is a milestone, certain functions may not be allowed.
  Project Status: The status of the project or task may prevent certain actions from being performed. For example, if a project is in a closed status, you may not be able to make changes.
  User Authorizations: The user may not have the necessary authorizations to perform the action on that specific task type.
  
  Solution:
  
  Check Task Type: Verify the type of task you are working with and ensure that the function you are trying to use is compatible with that task type.
  Review Project Structure: Look at the overall project structure and ensure that the task is set up correctly. If necessary, consult with a project manager or SAP consultant to confirm the task's configuration.
  Change Project Status: If the project or task is in a status that restricts actions, consider changing the status if appropriate and if you have the necessary permissions.
  User Authorizations: Ensure that you have the required authorizations to perform the action. If not, contact your SAP security administrator to request the necessary permissions.
  Consult Documentation: Refer to SAP documentation or help resources for specific details about the task type and the functions that can be used with it.
