• What is the cause and solution for SAP error message PLM_SE_PRS_MESSAGES034 - NetworkRelationship: Predecessor network must be the parent network. ?

  The SAP error message PLM_SE_PRS_MESSAGES034 indicates that there is an issue with the relationship between networks in a project or process. Specifically, the error states that the predecessor network must be the parent network. This typically occurs in the context of project management or process planning within SAP's Project Lifecycle Management (PLM) module.
  Cause:
  The error arises when you attempt to create or modify a network relationship where the predecessor network is not correctly defined as the parent of the successor network. In SAP, networks can have hierarchical relationships, and the system enforces rules to maintain the integrity of these relationships. If the predecessor network is not a direct parent of the successor network, the system will throw this error.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Network Hierarchy: Verify the hierarchy of the networks involved. Ensure that the predecessor network is indeed the parent of the successor network. You can do this by navigating to the network in question and checking its structure.
  
  
  Adjust Network Relationships:
  
  If the predecessor network is not the parent, you may need to adjust the network structure. This could involve changing the parent-child relationships or reassigning networks to ensure that the predecessor is correctly positioned as the parent.
  You can use transaction codes like CN21 (Create Network) or CN22 (Change Network) to modify the network relationships.
  
  
  
  Review Network Assignment: Ensure that the networks are assigned correctly in the project structure. If necessary, reassign the networks to the correct parent network.
  
  
  Consult Documentation: If you are unsure about the network structure or how to make the necessary changes, refer to SAP documentation or consult with your SAP administrator or a functional consultant who specializes in PLM.
  
  
  Testing: After making the necessary adjustments, try to recreate the relationship that caused the error to ensure that it is resolved.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CN21 (Create Network), CN22 (Change Network), and CN41 (Display Network) to manage networks effectively.
  SAP Notes: Check for any SAP Notes related to this error message for additional guidance or patches that may address known issues.
  User Roles and Permissions: Ensure that you have the necessary permissions to make changes to network structures, as restrictions may prevent you from modifying relationships.
  
  By following these steps, you should be able to resolve the error and maintain the integrity of your project or process networks in SAP.
