• What is the cause and solution for SAP error message PLM_SE_PRS_MESSAGES083 - A network cannot be its own parent. ?

  The SAP error message PLM_SE_PRS_MESSAGES083 ("A network cannot be its own parent") typically occurs in the context of project management or network planning within SAP, particularly when dealing with project structures or dependencies in the Project System (PS) module.
  Cause:
  This error arises when there is an attempt to create a hierarchical relationship where a network (or project) is incorrectly set as its own parent. In project management, a network should not reference itself as a parent because it creates a circular dependency, which is logically inconsistent and can lead to infinite loops in processing.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Network Structure: Review the network structure you are trying to create or modify. Ensure that no network is set as its own parent. 
  
  
  Correct Parent-Child Relationships:
  
  Navigate to the network in question.
  Check the parent network assignment.
  If the network is incorrectly assigned as its own parent, change it to reference a valid parent network.
  
  
  
  Use Transaction Codes: You can use transaction codes like CN21 (Create Network) or CN22 (Change Network) to review and modify the network structure.
  
  
  Validate Dependencies: Ensure that all dependencies and relationships between networks and activities are valid and do not create circular references.
  
  
  Consult Documentation: If you are unsure about the correct structure, refer to SAP documentation or guidelines on network planning and project structures.
  
  
  Testing: After making the necessary changes, test the network creation or modification process again to ensure that the error does not recur.
  
  
  Related Information:

  User Roles and Permissions: Ensure that you have the appropriate permissions to make changes to network structures, as restrictions may also lead to errors.
