• What is the cause and solution for SAP error message CN708 - No relationships to superior activity & must be created ?

  The SAP error message CN708 ("No relationships to superior activity & must be created") typically occurs in the context of project management and network planning within SAP. This error indicates that a subordinate activity does not have a defined relationship with its superior (or predecessor) activity, which is necessary for proper scheduling and planning.
  Cause:
  
  
  Missing Relationships: The primary cause of this error is that the subordinate activity (the one you are trying to create or modify) does not have any defined relationships (dependencies) with its superior activity. In project management, activities often depend on one another, and these dependencies must be explicitly defined in the system.
  
  
  Incorrect Activity Status: The status of the activities may not allow for the creation of relationships. For example, if an activity is marked as completed or has a status that prevents changes, you may encounter this error.
  
  
  Data Entry Errors: There may be data entry errors or inconsistencies in the project structure that lead to this issue.
  
  
  Solution:
  
  
  Create Relationships: To resolve the error, you need to create the necessary relationships between the subordinate activity and its superior activity. This can typically be done in the project planning screen:
  
  Navigate to the activity in question.
  Use the "Relationships" tab or section to define the required relationships (e.g., Finish-to-Start, Start-to-Start, etc.) with the superior activity.
  
  
  
  Check Activity Status: Ensure that both the superior and subordinate activities are in a status that allows for relationship creation. If an activity is completed or locked, you may need to change its status.
  
  
  Review Project Structure: Check the overall project structure to ensure that all activities are correctly defined and that there are no missing links or inconsistencies.
  
  
  Use Transaction Codes: You can use transaction codes like CJ20N (Project Builder) or CN21 (Create Network) to manage and review the project activities and their relationships.
  
  
  Consult Documentation: If you are unsure about the relationships needed, consult the project documentation or guidelines that outline the dependencies between activities.
  
  
  Related Information:
  
  SAP Documentation: Refer to SAP Help documentation for detailed information on project management and network planning.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CJ20N, CN21, CN22, and CN24 for managing project activities and networks.
  User Roles: Ensure that you have the necessary permissions to create or modify relationships in the project.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in project systems.
