• What is the cause and solution for SAP error message CJ594 - You selected some activities which are in header-assigned networks ?

  The SAP error message CJ594 indicates that you are trying to select activities that are part of a header-assigned network in a project, but the system does not allow this action. This typically occurs in the context of project management within SAP, particularly when dealing with networks and activities in Project System (PS).
  Cause:
  The error occurs because:
  
  Header-Assigned Networks: The activities you are trying to select are linked to a network that is assigned to a project header. In SAP, header-assigned networks are designed to manage activities at a higher level, and certain operations (like certain types of changes or selections) are restricted to maintain data integrity.
  Incorrect Selection: You may be trying to perform an operation that is not permitted on header-assigned networks, such as trying to change or delete activities that are not directly editable.
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Network Assignment: Verify if the activities you are trying to select are indeed part of a header-assigned network. You can do this by checking the network assignment in the project structure.
  
  
  Use the Correct Transaction: Ensure you are using the appropriate transaction code for the operation you want to perform. For example, if you need to change or display network activities, use transactions like CN22 (Change Network) or CN41 (Display Network).
  
  
  Modify the Network Structure: If you need to make changes to the activities, you may need to first detach them from the header-assigned network or change the network assignment. This can be done by:
  
  Changing the network type to a non-header assigned network if applicable.
  Creating a new network that is not header-assigned and moving the activities there.
  
  
  
  Consult Documentation: Review SAP documentation or help files related to Project System and network management for more detailed guidance on handling header-assigned networks.
  
  
  Seek Help from SAP Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting SAP Notes for any known issues or patches related to this error.
